Chapter 1 - Introduction
This guide’s purpose
The aim of this Technical guide No. 2* is to give a straight-forward
explanation of how the various EU Council Directives relate to
power drive systems (PDSs). For an explanation of the terminolo-
gy of PDSs, see pages 21 and 22.
While Electromagnetic Compatibility (EMC) is the subject of
most concern within the industry, it must be realised that the
EMC Directive is only part of the overall EU initiative on common
safety standards.
It is the intention of this guide to offer users of AC or DC power
drive systems - whether machine builders, system designers,
distributors, OEMs, end-users or installers - some clear practical
guidelines and courses of action.
*Notes
1 The content of this technical guide is ABB Oy’s, Drives in-
terpretation of events as of July 2007. However, we reserve
the right to develop and evolve these interpretations as more
details become available from notified bodies (see chapter 6),
competent authorities (see chapter 6), organisations and from
our own tests.

How to use this guide
The guide is divided into 7 sections.
Section 4 looks at purchasing decisions for PDSs. Please note
the following about the structure of this section:
Responsibilities and actions
Each type of purchaser is offered an explanation of their respon-
sibilities. This is for awareness. No action is needed.
Following the responsibilities is a set of actions. If the purchaser
follows these actions, step-by-step, then conforming to the
relevant directives will be straightforward.
Tickboxes
Alongside the actions are tickboxes. Purchasers can photocopy
the relevant pages and use them as a checklist with each item
being ticked off as it is achieved.
Cross-referencing
Because of the complexity of conforming to each directive, this
guide inevitably carries a lot of cross-references to other sec-
tions. In the margin you will come across:

Chapter 2 - General questions and answers
It is very important that users of PDSs fully understand all the
various rules and regulations and how they apply to PDSs. That
is the purpose of this guide.
What are these EU Council Directives?
It is important to realise that EMC cannot be divorced from other
European legislation. So before answering this question, we need
to look at the other legislation and how it affects the purchase
and installation of drives.
Quite simply there are three directives that mainly affect a drive’s
safety against risks and hazards. These are:
But more on each of these directives later. Let us first explain
EMC and look at some concerns of the industry.
How does EMC affect me?
From January 1, 1996 the EU Council’s Electromagnetic Com-
patibility Directive (89/336/EEC and it’s successor 2004/108/EC)
has been compulsory. It applies to all electrical and electronic
equipment sold within the EU and affects virtually all manufactur-
ers and importers of electrical and electronic goods.
Key point:
Electrical equipment that does not conform to the regulations
may not be sold anywhere in the EEA (European Economic Area).
What is EMC?
EMC stands for Electromagnetic Compatibility. It is the ability of
electrical/electronic equipment to operate problem-free within
an electromagnetic environment. Likewise, the equipment must
not disturb or interfere with any other products or systems within
its locality.

General questions and answers
What is an electromagnetic environment?
The electromagnetic environment is everywhere but it varies
from place to place. The reason is that there are many different
sources of disturbance which can be natural or man-made.
Natural sources consist of electrical discharge between clouds,
lightning or other atmospheric disturbances. While we cannot
influence these sources we can protect our products and sys-
tems from their effects.
Man-made disturbances are those generated by, for example,
electrical contacts and semiconductors, digital systems like mi-
croprocessors, mobile radio transmitters, walkie-talkies, portable
car telephones and power drive systems.
Such a variety of equipment, each with its own emission char-
acteristics, is often used so near to other electrical equipment
that the field strengths they create may cause interferences.
Key point:
It is important that all PDSs are immune to these natural and
man-made disturbances. While drives manufacturers strive to
make their products immune, the directive lays down minimum
standards for immunity, thereby ensuring all manufacturers
achieve the same basic level.
How does electromagnetic interference show up?
Electromagnetic interference shows up in a variety of ways.
Typical examples of interference include a poorly suppressed
automobile engine or dynamo; an electric drill causing patterning
on the TV screen; or crackling from an AM radio.
The microprocessor and power electronic component, switch
rapidly and therefore, can cause interference at high frequencies,
unless proper precautions are taken.
What emissions can drives cause?
The normal operation of any drive involves rapid switching of
high voltages and this can produce radio frequency emission. It
is this radiation and emission that have been seen to have the
potential to disturb other circuits at frequencies below 200 MHz.
Modern equipment contains considerable communications and
other digital electronics. This can cause considerable emissions
at frequencies above 200 MHz.

How is this emission seen?
The main emission is via conduction to the mains. Radiation
from the converter and conducting cables is another type of
emission and it is especially demanding to achieve the radiated
emission limits.
How do I avoid electromagnetic interference?
You need to ensure two things:
– that the equipment generates minimum emission.
– that the equipment is immune to outside effects.
Key point:
In the case of power drive systems, a lot hinges on the quality
of the installation.
Electromagnetic interference needs to be conducted to earth
(ground potential) and no system can work unless it is properly
connected.
Drives manufacturers must comply with EMC standards then?
Unfortunately, the process is not that simple. Virtually everyone
in the supply chain has a responsibility to ensure a product, a
system and an installation complies with the essential require-
ments of the EMC Directive.
The key is to clearly understand who has responsibility for what.
In the forthcoming pages we take a look at various types of
purchasers and examine the steps each should take to meet all
three directives mentioned on page 11.
Everyone from manufacturer to installer to user has a responsi-
bility in complying with EMC rules.
If a drive is CE marked, I need not worry. True?
Again this is a big misconception. Just because a drive has CE
marking does not necessarily mean it meets the EMC Directive.

Key point:
This will all become clear by referring to the section purchasing
decisions for PDSs, page 21.
CE marking according to the EMC Directive cannot normally be
applied to a module that is no more than a chassis with exposed
terminals.

Chapter 3 - CE marking
What is CE marking and how relevant is it for drives?
CE marking, shown below, is the official signature of the Dec-
laration of conformity (see pages 43 and 44) as governed by
the European Commission. It is a very specific graphic symbol
and must be separated from other marks.
CE marking is a system of self certification to identify equipment
that complies with the relevant applicable directives.
If a drive is the subject of several directives and, for example,
conforms with the Low Voltage Directive (see page 56), then,
from 1997, it is compulsory that it shows CE marking. That
marking shall indicate that the drive also conforms to the EMC
Directive (page 57). CE marking shall indicate conformity only
to the directive(s) applied by the manufacturer.
Key point:
NOTE: There must be technical documentation supporting the
Declaration of conformity.
For more on technical documentation, please refer to pages
from 36 to 40.
What is CE marking for?
CE marking is mainly for the benefit of authorities throughout
the EU and EEA countries who control the movement of goods.
CE marking shows that the product complies with the essential
requirements of all relevant directives, mainly in the area of techni-
cal safety, compatibility issues and conformity assessment. There
are three directives that are relevant to drives, but CE marking
may be attached to indicate compliance with one of them only
(see the previous page).

CE marking
Is CE marking a quality mark?
Most definitely not. As CE marking is self certification, you can
be assured that certification has been carried out.
What is the legal position regarding CE marking?
Anyone applying CE marking is legally liable and must be able
to prove the validity of his actions to the authorities. CE marking
confirms compliance with the directives listed in the Declaration
of conformity (see pages 43 and 44).
What is the importance of CE marking for purchasers of drives?
As far as a purchaser of a drive is concerned, anything that car-
ries the CE mark must have a functional value to him.
Thus, a complete drive product, which can be safely cabled and
powered up on its own, shall carry the CE marking.
If I buy a CE marked drive, will I meet the technical requirements of the
directives?
In practice, you will see drive products with CE marking. But it
is important to understand just why the product was given CE
marking in the first place.
Basically a drive has no functional value. It is only of practical
use when connected to, say, a motor which in turn is connected
to a load.
Therefore, as far as the Machinery Directive is concerned a drive
cannot have CE marking unless it is part of a “process” compris-
ing the drive, motor and load.
As for the EMC Directive, the equipment that make up a “proc-
ess” include cabling, drives and motor. CE marking can only be
affixed if all items forming such a “process” conform to the re-
quirements of the directive. Therefore, the drive manuals include
detailed instructions for installation.
However, in the eyes of the Low Voltage Directive, a built drive
does have functionality. That is, through the drive’s parameters
you can program the drive and obtain an input and output signal.
Thus, if a drive conforms to the Low Voltage Directive it can carry
CE marking. Refer to pages from 58 to 60 for explanations of
the three directives.

CE marking
What happens if, as an end-user, I put together a system -
do I have to put CE marking on?
Yes. Anyone putting together a system and commissioning it is
responsible for the appropriate CE marking.
Key point:
Turn to page 31 for more details about the end-user’s respon-
sibilities.
What about spare parts that I buy for a drive? Do I negate the CE mark if
I replace a component?
Equipment supplied before the application of the directives,
can be repaired and supplied with spare parts to bring it back
to the original specification. However, it cannot be enhanced or
reinstalled without meeting the directives.
For equipment supplied after the application of the directives,
the use of the manufacturer’s spare parts should not negate the
CE marking. However, the manufacturer or supplier should be
consulted about upgrading, as some actions could affect the
CE marking criteria.
If drives are classed as components, on subassemlies they cannot be
EMC certified or carry a CE mark. Is this true?
You need to first understand the terminology now being applied
to drives. See below and pages 21 and 22 for this.
A complete drive module (CDM) is normally a component in a
system and as such has no functional value unless it is connected
to the motor when it becomes a PDS.
The CDM shall be CE marked if it is to be installed with simple
connections and adjustments that do not require any EMC-
knowledge.
If awareness of the EMC implication is needed in order to install
a CDM, it is not considered as an apparatus. Thus, it shall not
be CE marked according to the EMC directives.
If a CDM or BDM is intended for incorporation in PDS by profes-
sional manufacturers only (panel builders, machine builders), it
shall not be CE marked, nor is Declaration of conformity given
by the CDM/BDM manufacturer. Instead installation instructions
shall be supplied in order to help the professional manufacturers.

In summary
The EMC Directive defines equipment as any apparatus or fixed
installation. As there are separate provisions for apparatus and
fixed installations, it is important that the correct category of the
equipment is determined.
In technical-commercial classifications the following terminol-
ogy is frequently used: components, sub-assemblies, finished
appliances (ie, finished products), a combination of finished
appliances (ie, a system), apparatus, fixed installations and
equipment.
The key issue here is whether the item to be considered is for
end users or not:
– If it meant for end users, the EMC directive applies
– If it meant for manufacturers or assemblers, the EMC direc-
tive does not apply
apparatus by the end users
A manufacturer may place components or sub-assemblies on
the market which are:
– For incorporation into an apparatus by the end-user,
– Available to end users and likely to be used by them.
These components or sub-assemblies are to be considered as
apparatus with regard to the application of the EMC. The instruc-
tions for use accompanying the component or sub-assembly
should include all relevant information, and should assume that
adjustments or connections can be performed by an end-user
not aware of the EMC implications.
In such case the component is considered equivalent to appa-
ratus. Some variable speed power drive products fall into this
category, eg, a drive with enclosure and sold as a complete unit
(CDM) to the enduser who installs it into his own system. All
provisions of the EMC Directive will apply (CE mark, Declaration
of conformity and technical documentation).
apparatus by the other manufacturer or assembler
Components or sub-assemblies intended for incorporation into
an apparatus or an other sub-assembly by other manufacturers
or assemblers are not considered to be “apparatus” and are
therefore not covered by the EMC Directive. These components
include resistors, cables, terminal blocks, etc.
CE marking

Some variable speed power drive products fall into this category
as well, eg, basic drive module (BDM). These are meant to be
assembled by a professional assembler (eg, panel builder or
system manufacturer) into a cabinet not in the scope of delivery
of the manufacturer of the BDM. According to the EMC Directive,
the requirement for the BDM supplier is to provide instructions
for installation and use.
Note:
The manufacturer or assembler of the panel or system is re-
sponsible for CE mark, Declaration of conformity and technical
documentation.
Finished appliance
A finished appliance is any device or unit containing electrical
and/or electronic components or sub-assemblies that delivers a
function and has its own enclosure. Similarly than components,
the interpretation finished appliance can be divided into two
categories: it can be intended for the end users, or for the other
manufacturers or assemblers.
Finished appliance intended for the end users
A finished appliance is considered as apparatus in the sense of
the EMC Directive, if it is intended for the end-user and thus has
to fulfill all the applicable provisions of the Directive.
Finished appliance intended for the other manufacturer or assembler
When the finished appliance is intended exclusively for an in-
dustrial assembly operation for incorporation into other appa-
ratus, it is not an apparatus in the sense of the EMC Directive
and consequently the EMC Directive does not apply for such
finished appliances.
Systems (Combination of finished appliances)
A combination of several finished appliances which is combined,
and/or designed and/or put together by the same person (ie,
the system manufacturer) and is intended to be placed on the
market for distribution as a single functional unit for an end-user
and intended to be installed and operated together to perform
a specific task.
All provisions of the EMC Directive, as defined for apparatus, apply to the
combination as a whole.
CE marking

CE marking
Apparatus
Apparatus means any finished appliance or combination thereof
made commercially available (ie, placed on the market) as a
single functional unit, intended for the end-user, and liable to
generate electromagnetic disturbance, or the performance of
which is liable to be affected by such disturbance.
Fixed installation
A particular combination of several types of apparatus, equip-
ment and/or components, which are assembled, installed and
intended to be used permanently at a predefined location.
Equipment
Any apparatus or fixed installation

Chapter 4 - Purchasing decisions for PDSs
What you need to know and do
Starting on page 23, we offer a step-by-step guide relating
to your purchasing requirements for power drive systems.
Key point:
Before turning to page 23, you need to know the following terms
for PDSs and their component parts, which may be unfamiliar
to many users.
1. Basic drive module (BDM) consists of the converter
section and the control circuits needed for torque or
speed. A BDM is the essential part of the power drive
system taking electrical power from a 50 Hz constant
frequency supply and converting it into a variable form
for an electric motor.
2. Complete drive module (CDM) consists of the drive
system without the motor and the sensors mechanically
coupled to the motor shaft. The CDM also includes
the Basic Drive Module (BDM) and a feeder section.
Devices such as an incoming phase-shift transformer
for a 12-pulse drive are considered part of the CDM.
3. Power drive system, or PDS, is a term used through-
out this technical guide. A PDS includes the frequency
converter and feeding section (the CDM and BDM), mo-
tors, sensors, all cabling, filters, panels and any other
components needed to make the PDS work effectively.
Note: The load is not considered part of the PDS, but the
CDM can incorporate the supply sections and ventilation.

Machine builder
is a person who buys either a PDS, CDM or BDM and
other mechanical or electrical component parts, such as a
pump, and assembles these into a machine.
Note: A machine is defined as an assembly of linked parts
or components, at least one of which moves. It includes
the appropriate actuators, control and power circuits
joined together for a specific application, in particular for
processing, treatment, moving or packaging of a material.
System designer
carries out all the electrical design of the power drive
system, specifying all component parts which comprise a
PDS.
28
End-user
is the final customer who will actually use the machine,
PDS or CDM/BDM.
31
Panel builder
constructs enclosures into which a panel builder will
install a variety of components, including a CDM/BDM
and sometimes the motor. However, the built enclosure
does not constitute a machine.

WHO ARE YOU?

NOTE: Before reading this section we strongly urge you to
familiarise yourself with the terms explained on pages 21-24.
If you are a machine builder buying a PDS...
...You have the following responsibilities:
1. Because you are building a complete machine, which in-
cludes coupling up the motors to the PDS and providing the
mechanical guarding and so on, you are liable for the total
mechanical and electrical safety of the machine as specified
in the Machinery Directive.
Therefore, the PDS is ultimately your responsibility. You need
to ensure that the entire PDS meets the Machinery Directive.
Only then can CE marking be applied to the whole machine.
2. You are also responsible for the electrical safety of all parts of
the PDS as specified in the Low Voltage Directive.
3. You must ensure electrical equipment and components are
manufactured in accordance with the EMC Directive. The
manufacturer of these parts is responsible for EMC for that
particular part. Nevertheless you are responsible for EMC for
the machine. You may choose electrical parts not in accord-
ance with the EMC directive, but then you have the respon-
sibility for compliance of parts.
Note: Be aware that combining CE marked sub-assemblies
may not automatically produce an apparatus that meets the
requirements.
4. You must ensure that the PDS or its component parts carry
declarations of conformity in accordance with the electrical
safety requirements of the Low Voltage Directive.
5. You must be able to assure an authority and customers
that the machine has been built according to the Machinery
Directive, the Low Voltage Directive and the EMC Direc-
tive. It may be necessary to issue technical documentation to
demonstrate compliance. You must keep in mind that you and
only you have responsibility for compliance with directives.
6. A Declaration of conformity according to the directives above
must be issued by the machine builder and CE marking must
then be affixed to the machine or system.
7. Any machine that does not comply must be withdrawn from
the market.

Actions you must take
To meet the Machinery Directive (see page 55) you need to:
a. Comply with the following mechanical safety checklist.
The aim is to eliminate any risk of accident throughout the
machinery’s life. This is not a complete list, the detailed
list is contained within the Machinery Directive:
Eliminate risk as far as possible, taking the necessary
protective measures if some risks cannot be eliminated.
Inform users of the residual risks; indicate whether any
training is required and stress the need for personal
protective equipment.
Machinery design, construction and instructions must
consider any abnormal use.
Under the intended conditions of use, the discomfort,
fatigue and stress of the operator must be reduced.
The manufacturer must take account of the operator’s
constraints resulting from the use of personal protective
equipment.
Machinery must be supplied with all essential equipment
to enable it to be used without risk.
b. Comply with the following electrical safety checklist: To ensure
the electrical safety of all parts of the PDS as specified in
the Low Voltage Directive (refer to page 56) you need to
comply with the following safety checklist, which is not
necessarily complete.
The electricity supply should be equipped with a discon-
necting device and with emergency devices for prevention
of unexpected start-up.
The equipment shall provide protection of persons against
electric shock from direct or indirect contact.

The equipment is protected against the effects of:
overcurrent arising from a short circuit.
overload current.
abnormal temperatures.
loss of, or reduction in, the supply voltage.
overspeed of machines/machine elements.
The electrical equipment is equipped with an equipotential bond-
ing circuit consisting of the:
– PE terminal.
– conductive structural parts of the electrical equipment and
the machine.
– protective conductors in the equipment or the machine.
The control circuits and control functions ensure safe
operation including the necessary inter-lockings,
emergency stop, prevention of automatic re-start, etc.
Defined on page 40
c. Compile a technical file for the machine, including the PDS.
Key point:
Generally, must carry CE marking and have a Declaration of
conformity.
For machines that pose a high risk of accident, a type certi-
fication (see page 46) is required from a notified body. Such
machinery is included in Annex IV of the Machinery Directive.
The type certificate issued should be included in the technical
file for the machine or safety component. Refer now to page 40.
2. Declarations of conformity from each of the
component suppliers whose products make up the PDS
and incorporate them into the technical documenta-
tion, referring to all three directives. If buying a
PDS from a system designer (see below), he should
be able to provide all declarations. If system designer
or component supplier cannot provide a Declaration
of conformity, the responsibility of demonstrating
compliance according to EMC Directive or Low
Voltage Directive lies on machine builder.

3. Pass this technical documentation to a notified
body. The machine builder SHOULD NOT pass
the file on to an end-user. Based on the technical
documentation, obtain a Certificate of Adequacy or
technical report from a notified body.
Defined on pages 43, 45 and 46
4. Issue a Declaration of conformity for the entire
machine. Only then can you apply CE marking.
5. Pass the Declaration of conformity related to all
three directives on to the end-user of the machine.
6. Apply CE marking to the machine.
7. Congratulations! You have successfully complied with
the main requirements for safe and efficient operation
of a machine.
When buying a PDS...
1. The PDS is a complex component of the machine. Therefore,
the Machinery Directive has to be complied with by issuing
a Declaration of incorporation.
2. Because a PDS is not a machine, the only directives which
need to be complied with are the Low Voltage Directive and
the EMC Directive.
3. The responsibility for Declaration of conformity and apply-
ing CE marking rests with both the system designer and the
supplier of the component parts which make up the power
drive system.

The system designer has to decide if he is going to place his
delivery on the market as a single functional unit or not
– if the answer is YES, the delivery shall be classified as a
system.
– if the answer is NO, the delivery shall be classified as an
installation.
A. If the delivery is classified as a system, the system designer
has to choose one of two paths to follow:
Path 1
All components have EMC compliance
1. EMC behaviour is based on a component’s performance.
2. Responsibility lies with the component suppliers for CE
marking of individual complex components
3. PDS is an system according to the EMC Directive (as placed
on the market as a single functional unit).
4. The Declaration of conformity as well as the instructions for
use must refer to the system as whole. The system designer
assumes responsibility for compliance with the Directive.
Note 1: The system designer is responsible for producing the
instructions for use for the particular system as whole.
Note 2: Be aware that combining two or more CE marked sub-
assemblies may not automatically produce a system that meets
the requirements.
5. No CE marking is required for a system as whole, as long as
each part bears the CE mark.
1. Follow all installation guidelines issued by each of
the component suppliers.
2. Issue instructions for use in order to operate the
system.
3. Issue technical documentation for the system.
4. Issue a Declaration of conformity.
5. DO NOT issue a CE mark.

Path 2
Components without EMC compliance
1. EMC behaviour is designed at the system level
(no accumulated cost by device specific filters etc).
2. Responsibility lies with the system designer who decides the
configuration (place or a specific filter etc).
3. PDS is a system according to the EMC Directive
(as placed on the market as a single functional unit).
4. Declaration of conformity and CE marking are required for
the system.
1. Follow the installation guidelines issued by each
of the component suppliers.
2. Optimise the construction of the installation to ensure
the design meets the required EMC behaviour, ie, the
location of filters.
Defined on pages 36 - 46
system.
5. Issue a Declaration of conformity and CE mark.
B. If the delivery is an installation, the system designer has one
path to follow:
Path 3
All components have EMC compliance
1. EMC behaviour is based on a component’s performance.
2. Responsibility lies with the component suppliers for CE
marking of individual complex components.
3. PDS is an installation according to the EMC Directive.
4. No Declaration of conformity or CE marking is required for a
fixed installation, (such as an outside broadcast radio station)
DOC and CE marking are needed.

1. Follow all installation guidelines issued by each of
2. Transfer all installation guidelines and Declaration
of conformity for each of the components, as issued
by suppliers, to the machine builder.
3. DO NOT issue a Declaration of conformity or CE
marking as this is not allowed for ﬁxed installations.
If you are an end-user buying a CDM/BDM or PDS
Key point:
An end-user can make an agreement with the drive’s supplier
so that the supplier acts as the machine builder. However, the
end-user is still responsible for the machine’s safety.
The supplier who acts as the machine builder will issue a Dec-
laration of conformity when the work is complete.
Once an intermediary panel builder incorporates a CDM/BDM
into a panel, he creates a part of a PDS.
The panel builder then has the same responsibilities as the drive’s
manufacturer.
...You have the following responsibilities
1. For the total mechanical and electrical safety of the machine
of which the drive is part of, as specified in the Machinery
Directive.
2. For the electrical safety of the drive as specified in the Low
Voltage Directive.

3. To ensure the drive carries a Declaration of conformity in
accordance with the electrical safety requirements of the Low
Voltage Directive.
4. To be able to demonstrate to the authorities that the machine
to which the drive is being fitted has been built to both the
Machinery Directive and Low Voltage Directive.
5. The manufacturer of the drive is responsible for determining
the EMC behaviour of the drive.
6. The resulting EMC behaviour is the responsibility of the as-
sembler of the final product, by following the manufacturer’s
recommendations and guidelines.
The following needs to be completed by either the end-user
directly or the third party engaged to build the machine.
1. To meet the Machinery Directive (refer to page 55) you need
to follow the actions listed for a machine builder on pages
25-28.
2. Follow installation instruction issued by manufacturers in order
to fulfill the requirements of the EMC Directive and the Low
Voltage Directive.
3. Ensure that equipment (CDM/BDM/PDS) is operated according
to manufacturer’s instruction in order to guarentee right way
of operation.
If you are a panel builder buying a CDM/BDM
1. The panel builder has two options:
Option A - To buy non-CE marked components
This could save the panel builder money because he buys
components which are not tested for EMC or safety. However,
the responsibility is then the panel builder’s and this will incur
considerable costs as the entire panel needs to be tested.

If the panel builder buys non-CE marked components, the
drive may be made to conform without further testing if the
components themselves have been tested. However, tested
components do not carry the CE mark but must carry suitable
instructions for installation. It is these instructions which must
be demonstrably met.
Option A - Actions to meet these responsibilities
1. Follow the installation guidelines issued by each of
2. Optimise the construction of the installation to ensure
the design meets the required EMC behaviour, ie, the
location of filters.
4. If you choose to assess yourself you must make
reference to EMC Directives:
2004/108/EC;
And to harmonised standard:
EN 61800-3
And you must make reference to LVD Directive:
2006/95/EC
And corresponding harmonized standard:
EN 61800-5-1 or EN 50178
Defined on pages 36-46
5. Once testing is completed, the results need to be
included in the technical documentation (TD)
for the panel.
6. Technical documentation shall be assessed by
youself in order to demonstrate compliance. You
may use Notified Body for assessment as well.
7. You must then issue the Declaration of conformity
and CE marking for the panel.

Option B - To buy CE marked components
Option B - Actions to meet these responsibilities
1. Buying CE marked components creates a system or
an apparatus (refer to page 17-20) depending on the
nature of the panel.
2. Although the panel builder does not have to carry out
tests, he must ensure he conforms to the installation
guidelines given by each of the component
manufacturers.
Note: Be aware that combining two or more CE-
marked components may not automatically produce
a system, which meets the requirements.
3. Beware! These guidelines could differ greatly from
those given for normal installation purposes because
the components will be in close proximity to each
other.
system or apparatus.
5. Issue technical documentation.
6. Issue a Declaration of conformity.
7. Apply CE marking to your panel in the case of an
apparatus. In the case of a system DO NOT apply CE
marking.
Additional actions
The panel can be either sold on the open market or use as part
of a machine. For each option there is a different requirement:
1. If you know that the panel is to be used as part of a
machine then you must request from the CDM / BDM
manufacturer a Declaration of incorporation.
2. The Declaration of incorporation must be supplied
with the panel to the machine builder, but CE
marking based on Machinery Directive MUST NOT be
affixed. This is because CE marking always needs a
Declaration of conformity.

Key point:
The Declaration of incorporation CAN NOT be used to apply
CE marking.
3. The machine builder will need this Declaration of
incorporation because he has to construct a
technical documentation (TD) for the machine and
in that file all the declarations need to be included.
If you are a distributor buying a CDM/BDM...
1. If a distributor is selling boxed products, like CDMs and BDMs
(drives), direct from the manufacturer, his only responsibility is
to pass on the installation guidelines to the end-user, ma-
chine builder or system designer. In addition, the Declara-
tion of conformity must be passed to the machine builder
or system designer.
2. Both the installation guidelines and the Declaration of
conformity are available from the manufacturer.
Actions you must take to meet these responsibilities
1. Pass all installation guidelines and declaration of con-
formities to either the end-user, machine builder or system
designer.
If you are an installer buying a CDM/BDM or PDS...
1. You must ensure that the installation guidelines of the ma-
chine builder and/or system designer are adhered to.
Actions you must take to meet these responsibilities
1. Follow machinery builder and/or system designer Instal-
lation guidelines.
2. See Technical guide No. 3 for recommended installation
guidelines.

Chapter 5 - Terminology
Technical documentation (TD)
APPLIED TO: electrical equipment
RESPONSIBILITY: electrical equipment manufacturer,
system designer, panel builder, OEM,
installer
REQUIRED BY: EMC Directive, Low Voltage Directive
What is technical documentation?
Technical documentation (TD) must be provided for the entire
equipment or system and if required is to show a competent
authority that you have met the essential requirements of the
EMC Directive (see page 57) and Low Voltage Directive (see
page 56).
The TD consists of three parts:
1. A description of the product.
2. Procedures used to ensure conformity of the product to the
requirements.
3. A statement from a notified body, if third party assessment
route is chosen.
Note: Using a notified body is voluntary and can be decided
by the manufacturer
Key point:
The full content of the technical documentation are given on
pages 36-39.
Why is technical documentation deemed to be important?
Anyone placing a product onto the market within the EU must
be able to show that the product meets the requirements of the
appropriate EU Council Directive and must be able to dem-
onstrate this to a competent authority without further testing.
Technical documentation allows the appropriate Declaration of
conformity to be drawn up.

Will customers always receive a copy of technical documentation?
The content of the technical documentation is meant for the
authorities, and thus the electrical equipment manufacturer does
not have to give the technical documentation or any part of it
to the customer.
However, as the customer needs to know whether the product
is in conformance, he will obtain this assurance from the docu-
mentation delivered with the product. It is not required to supply
a declaration of conformity with the product, but the end-user
may ask for this from the manufacturer.
What is the shelf life of technical documentation?
Any technical documentation must be accessible to the ap-
propriate authorities for 10 years from the last relevant product
being delivered.
How do I ensure that tests are always carried out?
The whole system is based on self certification and good faith.
In various parts of Europe the methods of ensuring compliance
will vary. Supervision of these regulations is achieved through
market control by a competent authority. If the equipment fails
to meet the requirements of the EMC and Low Voltage Directives
competent authorities can use the safeguard clause of the Direc-
tives (withdraw the product from the market, take legal action).
Can drive manufacturers help more?
Manufacturers accept that there is a need to work more closely
with OEMs and machine builders where the converter can be
mounted on the machine. A standard assembly or design should
be achieved so that no new parts of technical documentation
need to be created.
However, the idea of mounting drives in motor control centres
(MCCs) must be much more carefully thought out by system
specifiers.
The concept of mounting several drives in a motor control
centre must be more carefully thought out, as the summing of
high frequency emissions to determine the effects at the MCC
terminals is a complex issue and the possibilities of cross cou-
pling are multiplied.

parts, to ensure they carry CE marking.

Technical file (for mechanical safety aspects)
APPLIED TO: machines and safety components
RESPONSIBILITY: machine builder / system designer
REQUIRED BY: Machinery Directive
What is a technical file?
A technical file is the internal design file which should show how
and where the standards are met and is all that is needed if self
certifying the equipment by the standards compliance route.
If a Declaration of incorporation is included in a set of papers and
this claims to meet the appropriate parts of the standards and
simply instructs the user to meet the standards with other parts of
his machine, it is possible to use this as a part of a technical file.
How to make up a technical file
Drawings and diagrams
1. Overall drawings of the machine.
2. Control circuit diagrams.
Health and safety
1. All drawings, calculations and test results used to check the
machine’s conformity with essential health and safety require-
ments.
Machine design
1. Lists of the essential health and safety requirements, harmo-
nised standards, other standards and technical specifications
used when designing the machine.
2. Description of methods used to eliminate hazards presented
by the machine.
Other certificates required
1. A technical report or certificate issued by a notified body
- if required.
2. A copy of the instructions for the machine.

3. For series produced machines, the control measures that
are used to ensure that subsequent manufacture remains in
conformity with the directive.
Certificate of Adequacy
APPLIED TO: machines / safety components
RESPONSIBILITY: notified body / machine builder
What if standards cannot be wholly implemented?
In this case the adequacy of the technical file is proved by a
Certificate of Adequacy issued by a notified body.
How to obtain a Certificate of Adequacy
The Certificate of Adequacy is a document drawn up by a
notified body. Once the body has established that the techni-
cal file contains all the necessary information, the Certificate
of Adequacy will be issued.
Key point:
The Certificate of Adequacy provided should be included in
the technical file.
Statement
RESPONSIBILITY: notified body
REQUIRED BY: EMC Directive
When the statement is needed
The primary way for manufacturer (or his authorised representa-
tive in the Community) to demonstrate the compliance is to use
internal production control method. If the manufacturer chooses,
he may use other method based on an assessment of a noti-
fied body.
Terminology

How to obtain the statement
The manufacturer shall present the technical documentation to
the notified body and request the notified body for an assess-
ment thereof. The manufacturer shall specify to the notified body
which aspects of the essential requirements must be assessed.
The notified body shall review the technical documentation
and assess whether the technical documentation properly
demonstrates that the requirements of the Directive. If the com-
pliance of the apparatus is confirmed, the notified body shall
issue a statement confirming the compliance of the apparatus.
Key point:
The statement provided shall be included in the technical
documentation.
Report
RESPONSIBILITY: notified body / competent body
REQUIRED BY: Low Voltage Directive
What if standards cannot be wholly implemented?
In the event of a challenge the manufacturer or importer may
submit a report issued by a notified body. This report is based
on the technical file.
How to obtain a report
The report is a document drawn up by a notified body. Once the
body has established that the technical documentation contains
all the necessary information and the equipment fulfils the require-
ments of the Low Voltage Directive, the report will be issued.
Key point:
The report provided should be included in the technical docu-
mentation.

Declaration of incorporation
APPLIED TO: machines or equipment intended for
incorporation into other machinery
RESPONSIBILITY: drives manufacturer / machine builder /
panel builder
What is a Declaration of incorporation?
Drives manufacturers must meet the appropriate parts of the
Machinery Directive and provide a Declaration of incorporation
which states that the drive does not comply on its own and must
be incorporated in other equipment.
This declaration will show the standards that have been applied
to the parts of the system within the manufacturer’s scope.
This declaration includes a statement restricting the user from
putting the equipment into service until the machinery into which
it is to be incorporated, or of which it is to be a component, has
been found, and declared, to be in conformity with the provi-
sions of the Machinery Directive and the national implementing
legislation, ie, as a whole including the equipment referred to in
this declaration.
Terminology

The declaration then lists the standards relating to the Machinery
and Low Voltage Directives which the manufacturer has met.
It concludes that the entire equipment must meet the provisions
of the directive.
Quite simply, the manufacturer passes on the responsibility to
the machine or system builder.
Is there no way out of this type of declaration?
No. You must understand that because the manufacturer may
be supplying only one part in a machinery, such as the inverter,
the manufacturer is legally obliged to ensure that whoever puts
the system together must check that it is safe.
Only then can the machine or system builder use the Declaration
of incorporation in his technical file of the machine.
Key point:
Most manufacturers will include a Declaration of incorporation
covering the Machinery Directive for all built PDS products.
What a Declaration of incorporation contains
1. business name and full address of the manufacturer or his
authorised representative;
2. description and identification of the partly completed machin-
ery including generic denomination, function, model, type,
serial number and commercial name;
3. a sentence declaring which essential requirements of the
Directive are applied and fulfilled;
4. an undertaking to transmit, in response to a reasoned request
by the national authorities, relevant information on the partly
completed machinery;
5. a statement that the partly completed machinery must not be
put into service until the final machinery into which it is to be
incorporated has been declared in conformity with the provi-
sions of the Directive;
6. the place and date of the declaration as well as the identity and
signature of the person empowered to draw up the declaration
on behalf of the manufacturer or his authorised representative.

Type certification
APPLIED TO: machines and safety components
RESPONSIBILITY: machine builder / approved body
How to obtain type certification
Type certification is carried out by an notified body who will es-
tablish that the unit supplied, along with a technical file, may be
used safely and that any standards have been correctly applied.
Once the type certification has established this, a type exami-
nation certificate will be issued.
Terminology

Chapter 6 - Authorities and bodies
The responsibility for product conformity is given to the manufac-
turer. If there is any doubt about conformity, then the Authorities
can demand technical documentation to show that a product
complies with the directives concerning the product.
When assessing product conformity, a manufacturer can use a
third party to examine the conformity.
The following types of authorities and bodies exist:
Competent authority
A competent authority in any EU or EEA country supervises
markets to prevent hazardous products being sold and marketed.
They can also withdraw such products from markets.
Notified body
A notified body issues type certificates for products, which have
their own directives and/or require type testing.

Chapter 7 - Standards and directives
The use of standards is voluntary, but compliance with directives
without the use of harmonised standards is extremely difficult.
There are two ways to show that a power drive system or part
of it conform:
– Use of harmonised standards (EN).
– By way of a technical documentation when no harmonised
standards exist, or if all parts of a harmonised standard can-
not be applied.
Key point:
It is recommended to use technical documentation even when
standards are harmonised as it makes it easier to show conform-
ity afterwards, if required by authorities.
Directive or standard?
The legislation of the European Union is defined by different
directives.
The directives concerning power drive systems are known as
new approach directives, which means that they do not include
exact figures or limits for products. What they do include is es-
sential requirements mainly for health and safety which make
the application of the relevant harmonised standards mandatory.
The requirements of directives are firmly established in standards.
Standards give exact figures and limits for products.
The responsibility for defining standards in Europe rests with three
committees: CEN, for areas of common safety, CENELEC, for
electrical equipment and ETSI, for telecommunications.
Harmonised standards for PDSs
To remove technical barriers to trade in EU or EEA countries,
the standards are harmonised in member states.
In the harmonisation procedure, all member states are involved
in developing the Committee’s proposals for their own national
standard. A standard becomes harmonised when published in
the Official Journal of the EU.

The idea is that if a product conforms to the harmonised
standard, it is legally manufactured and when placed onto
the market in one country, it must be freely marketed in other
member countries.
How to recognise a European standard
Harmonised standards come in the following format:
XX EN 60204-1
where
XX = the national prefix (eg BS = UK; SFS = Finland)
EN = the abbreviation of Euronorm
60204-1 = an example of a standard number
The numbering of European standards follows a well structured
and organized sequence:
– EN 50225:1996 (the year of availability of the EN is separated
from the number by a colon)
– EN 50157-2-1:1996 (the part number is indicated by a hy-
phen)
The first two numerals indicate the origin of the standard:
– 40xxx to 44xxx cover domains of common CEN/CENELEC
activities in the IT field
– 45xxx to 49xxx cover domains of common CEN/CENELEC
activities outside the IT field
– 50xxx to 59xxx cover CENELEC activities, where
– EN 50xxx refer to the standards issued by CENELEC only
– EN 55xxx refer to the implementation of CISPR documents
– 60000 to 69999 refer to the CENELEC implementation of IEC
documents with or without changes
European standards are adopted and confirmed by CENELEC
member countries by adding national prefix before the stand-
ard id (for example: SFS-EN 60601-1, DIN EN 60601-1, BS EN
60601-1).
There is also some clue as to a standard’s status:
prEN 50082-2 = proposal for standard sent to member states
ENV 50 = pre-standard which is in force for 3 years to
obtain practical experience from member
states
Standards and Directives

Your questions answered
Which standards directly relate to drives?
At the moment, there are three Product Specific Standards
(see page 50) which relate to the compliance with EU directives.
They are called as “EN 61800-3 Adjustable speed electrical
power drive systems. Part 3: EMC product standard includ-
ing specific test methods”, which relates to EMC Directive,
“EN 61800-5-1 Adjustable speed electrical power drive systems.
Part 5-1: Safety requirements. Electrical, thermal and energy”,
which relates to Low Voltage Directive and EN 61800-5-2,
Part 5-1: Safety requirements. Electrical, thermal and energy”,
which relates to Low Voltage Directive and “EN 61800-5-2
Adjustable speed electrical power drive systems. Part 5-2: Safety
requirements. Functional safety”, which relates to Machinery
Directive.
In addition there are other standards which need to be taken
account:
– EN 60204-1, Electrical Equipment of Machines, which, in
addition to being a Low Voltage Directive standard for all
electrical equipment, is also an electrical safety standard
under the Machinery Directive.
– EN 50178 according to Low Voltage Directive and
– EN 61800-1/2/4, which give rating specifications for Power
Drive Systems (LV DC, LV AC and MV AC PDS respectively).
– EN 61000-3-2 and EN 61000-3-12 which give requirements
for harmonic current caused by equipment
What are the issues of EN 61800-3 and drives?
For emissions there are two main aspects to be considered:
Conducted emissions: these are seen on the power supply
cables and will also be measured on the control connections,
while radiated emissions are air borne.
Conducted emissions at low frequencies are known as har-
monics which have been a familiar problem to many users of a
PDS. Where harmonics are concerned EN 61800-3 refers to EN
61000-3-2 which applies for equipment under 16 A per phase.
In addition, the harmonics standard EN 61000-3-12 applies up
to 75 A per phase.
At the moment following groups can be separated
– Below 16 A per phase
– Professional, over 1kW => No limits.
– Other > the limits specified.
– Between 16 A and 75 A per phase

– Equipment for public low voltage systems => the limits
specified.
– Equipment for other systems => the limits specified
Conformity with conducted emissions can be helped by good
product design and is readily achieved, in most situations, using
filters, providing this is for a single drive.
Radiated emissions: These are more problematic. While it is
possible to make the drive enclosure into a Faraday cage and
thereby have all radiation attenuated to earth, in practice it is
the outgoing connections where inadequate cabling radiates
emissions and cross couples with other cables in the vicinity.
Important attenuation methods are shielded cables and 360o
grounding.
What are the solutions to radiated emissions?
The most important solutions are good installation practice, tight
enclosure, shielded cables and 360o
grounding. (See Technical
guide No. 3 for tips and advice).
Do I have to conform to the standards?
The use of standards is voluntary, but compliance with a Direc-
tive without the use of Harmonised Standards is difficult in the
majority of cases.
Can I be fined for not conforming?
Yes. Failure to comply with any of the Directives will be a criminal
offence.
The Product Specific Standard EN 61800-3
This standard defines the required emission and immunity levels
of PDSs and the test methods to measure the levels. In Europe,
the standard takes precedence over all generic or product family
EMC standards previously applicable.
The standard defines two environments where equipment can
be used:
First environment
– environment that includes domestic premises, it also includes
establishments directly connected without intermediate trans-
formers to a low-voltage power supply network which supplies
buildings used for domestic purposes. Houses, apartments,
commercial premises or offices in a residential building are
examples of this kind of locations.

Second environment
– environment that includes all establishments other than those
directly connected to a low voltage power supply network
which supplies buildings used for domestic purposes. Indus-
trial areas, technical areas of any building fed from a dedicated
transformer are examples of second environment locations
The standard divides PDSs and their component parts into four
categories depending on the intended use
PDS of category C1:
A PDS with rated voltage less than 1,000 V and intended
for use in the first environment. A (PDS (or CDM) sold “as
built” to the end-user.
Description
Placed on the market. Free movement based on compliance with
the EMC Directive. The EC Declaration of Conformity and CE
Marking are required.
The PDS manufacturer is responsible for EMC behaviour of the
PDS under specified conditions. Additional EMC measures are
described in an easy-to-understand way and can be implemented
by a layman.
When PDS/CDM is going to be incorporated with another
product, the resulting EMC behaviour of that product is the
responsibility of the assembler of the final product, by following
the manufacturer’s recommendations and guidelines.
PDS of category C2:
PDS with rated voltage less than 1,000 V, which is neither a
plug in device nor a movable device and is intended to be
installed and commissioned only by a professional.
A PDS (or CDM/BDM) sold to be incorporated into an ap-
paratus, system or installation.
Description:
Placed on the market. Intended only for professional assemblers
or installers who have the level of technical competence of EMC
necessary to install a PDS (or CDM/BDM) correctly. The manu-
facturer of the PDS (or CDM/BDM) is responsible for providing
Installation Guidelines. The EC Declaration of Conformity
and CE Marking are required.

When a PDS/CDM/BDM is to be incorporated with another
responsibility of the assembler of the final product.
PDS of category C3:
PDS with rated voltage less than 1,000 V, intended for use
in the second environment.
A PDS (or CDM/BDM) sold “as built” to the end-user or
in order to be incorporated into an apparatus, system or
installation.
Description
Placed on the market. Free movement based on compliance with
the EMC Directive. The EC Declaration of Conformity and CE
Marking are required.
The PDS manufacturer is responsible for EMC behaviour of the
PDS under specified conditions. Additional EMC measures are
described in an easy-to-understand way and can be implemented
by a layman.
When PDS/CDM is going to be incorporated with another
responsibility of the assembler of the final product, by following
the manufacturer’s recommendations and guidelines.
PDS of category C4:
PDS with rated voltage equal to or above 1,000 V, or rated
current equal to or above 400 A, or intended for use in com-
plex systems in the second environment.
A PDS (or CDM/BDM) sold to be incorporated into an ap-
paratus, system or installation.
Description
Category C4 requirements include all other EMC requirements
but radio frequency emission. They assessed only when it is
installed in its intended location. Therefore category C4 PDS is
treated as a fixed installation, and thus has no requirement for
EC Declaration of Conformity or CE Marking.
The EMC directive requires the accompanying documentation
to identify the fixed installation, its electromagnetic compatibility
characteristics and responsible person, and to indicate the pre-
cautions to be taken in order not to compromise the conformity
of that installation.

In order to comply the above requirements in the case of cat-
egory C4 PDS (or CDM/BDM), the user and the manufacturer
shall agree on an EMC plan to meet the EMC requirements of the
intended application. In this situation, the user defines the EMC
characteristics of the environment including the whole installation
and the neighborhood. The manufacturer of PDS shall provide
information on typical emission levels and installation guidelines
of the PDS which is to be installed. Resulting EMC behaviour is
the responsibility of the installer (eg, by following the EMC plan).
Where there are indications of non-compliance of the category
C4 PDS after commissioning, the standard includes procedure
for measuring the emission limits outside the boundary of an
installation.
Examples concerning applications of different approaches
1. BDM used in domestic or industrial premises, sold without
any control of the application.
The manufacturer is responsible that sufficient EMC will be
achieved even by a layman. Although the EMC Directive ap-
plies to the apparatus and fixed installations only (generally
components are excluded), it states that the components which
are intended for incorporation into apparatus by the end user
and which liable to generate electromagnetic disturbances are
included. Thus, if members of the public (end-users) buy a com-
ponent off the shelf, they will not have to worry about compliance
when they fit it to their machine. Therefore, the responsibility for
compliance and CE Marking such components under EMC lies
with the manufacturer. Depending of intended installation location
category C1 or C3 equipment is allowed.
2. PDS or CDM/BDM for domestic or industrial purposes,
sold to professional assembler.
This is sold as a sub-assembly to a professional assembler who
incorporates it into a machine, apparatus or system. Condi-
tions of use are specified in the manufacturer’s documentation.
Exchange of technical data allows optimisation of the EMC
solutions. In addition of categories C1 and C3, also category
C2 is allowed.
3. PDS or CDM/BDM for use in installations.
The conditions of use are specified at the time by the purchase
order; consequently an exchange of technical data between sup-
plier and client is possible. It can consist of different commercial
units (PDS, mechanics, process control etc).

The combination of systems in the installation should be con-
sidered in order to define the mitigation methods to be used to
limit emissions. Harmonic compensation is an evident example
of this, both for technical and economical reasons.
In addition of categories C1, C2 and C3, also category C4 is
allowed.
4. PDS or CDM/BDM for use in machine.
PDS or CDM/BDM combined with application device (machine)
such as a vacuum cleaner, fan, pump or such like, ie, ready to
use apparatus. Similarly inverters (E.Q. subassemblies of BDMs)
come under this class of components. On their own they do
not have an intrinsic function for the end-user, but are sold to
professional installers who incorporate them into a machine, ap-
paratus or system. They are not on sale directly to the end-user.
Therefore for EMC Directive point of view the PDS/CDM/BDM
here is a component which is excluded from the directive. The
machine builder is responsible for all EMC issues. The manufac-
turer of PDS/CDM/BDM is responsible for providing installation,
maintenance and operation instructions to the machine builder
in order to achieve compliance with EMC Directive.
Nevertheless, it is recommended to use category C1, C2, C3 or
C4 PDS/CDM/BDM rather than drives without any compliance.
Machinery Directive 98/37/EC
How does the Machinery Directive affect my drive?
This directive concerns all combinations of mechanically joined
components, where at least one part is moving and which have
the necessary control equipment and control and power input
circuits.
The directive concerns all machines but not those like lifts, which
have a specific directive.
The new machinery Directive 2006/42/EC has been published.
Since the old directive 98/37/EC can be used until December
29, 2009, the changes due to the new directive will be consider
in the future editions of this Guide.

Key point:
As far as drives are concerned, the new version of EN 60204-1,
ed. 5, is already published. The old and the new versions can
be used until June 1, 2009. After that date only the new version
shall be applied.
On its own, the complete drive module (CDM) does not have
a functional value to the user. It always needs its motor coupled
to the driven load before it can function effectively. Thus, it can-
not carry the CE marking based on the Machinery Directive.
Where can I obtain a Machinery Directive copy?
To obtain a copy of the Machinery Directive you can contact a
local competent authority or download it from European Unions
web-site related to the legislation (http://europa.eu.int/eur-lex/).
Low Voltage Directive
How does the LVD affect my drive?
2006/95/EC
This directive concerns all electrical equipment with nominal
voltages from 50 V to 1 kV AC and 75 V to 1.5 kV DC.
The aim of the directive is to protect against electrical, mechani-
cal, fire and radiation hazards. It tries to ensure only inherently
safe products are placed on the market.
All parts of a PDS from converters and motors to control gear
must conform with the Low Voltage Directive.
To guarantee that a product complies, the manufacturer must
provide a Declaration of conformity. This is a Declaration that
the product conforms to the requirements laid down within this
Directive.
If a product conforms to the Directive and has a Declara-
tion of conformity, then it must carry the CE marking.
In the case of a power drive system, the Declaration of con-
formity is needed for each of its component parts. Thus, the
Declaration of conformity for the complete drive module (CDM)
and for the motor have to be given separately by the manufac-
turer of each product.

Key point:
Most manufacturers will include a Declaration of conformity
covering the Low Voltage Directive for all built PDS/CDMs.
These are drives built into an enclosure, which can be wired
up to the supply and switched on without any further work being
undertaken. This is in contrast to an open chassis (BDM), which
is a component and needs an enclosure.
Why is the Declaration of conformity important?
Key point:
Without the Declaration of conformity the CDM could not carry
the CE marking and therefore it could not be sold within EEA
countries and therefore could not be used legally in any system.
EMC Directive
How does the EMC Directive affect my drive?
2004/108/EC
The intention of the EMC Directive is, as its name implies, to
achieve EMC compatibility with other products and systems.
The directive aims to ensure emissions from one product are low
enough so as not to impinge on the immunity levels of another
product.
There are two aspects to consider with the EMC Directive:
– the immunity of the product.
– the emissions from that product.
Although the directive expects that EMC should be taken into
account when designing a product, in fact EMC cannot be han-
dled by design only – it shall be measured quantitatively as well.
Key point:
Most drives bear CE-marking. Newertheless, some cases drives
are part of the machinery or process equipment/system and
classified as components they are not included into the EMC
directive.
The machine builder, therefore, has the final responsibility to
ensure that the machine including any PDS and other electrical
devices, meets the EMC requirements.

At each stage of the manufacturing process, from component
to system, each manufacturer is responsible for applying the
appropriate parts of the directive. This may be in the form of
instructions on how to install or fit the equipment without causing
problems. It does not imply that there is a string of Declarations
of conformity to be compiled into a manual.
Who has the responsibility to ensure CE marking?
A frequency converter is likely to be only a part of a power drive
system.
Yet it is the entire system or machinery that must meet the re-
quirements of the EMC Directive.
So, drives manufacturers are in a position to choose whether to
put CE marking on to a frequency converter to indicate com-
pliance with the EMC Directive or to deliver it as a component
without CE marking.
Key point:
It is the responsibility of the person who finally implements the
system to ensure EMC compliance.
Either the machine builder or system supplier has the final
responsibility that the machine or system including the drive
and other electrical and electronic devices will meet the EMC
requirements.
A drive manufacturer is able to help machine builder or system
supplier by providing BDM/CDM/PDS which are according to
the EMC directive and CE-marked.

Summary of responsibilities
Summary of manufacturer’s responsibilities in the application of
EC Directives to systems containing a PDS:
If some of the directives result in CE marking, the PDS (or CDM or BDM)
can be CE marked with the corresponding Declaration of conformity.
