Equipment Construction Detail

Serialized Circuit Boards
We serialize and track all critical circuit boards and memory cards
through our eBOSS portal, which allows customers to reference
which components their machines are made from, who tested the
components, as well as the ability to view notes generated from
testing.
Serialized components offer the ability to drill-down on prospective
component failure utilizing predictive modeling techniques, so if part
fails, the instance can be cross-referenced with similar parts. This
preventative maintenance helps ensure maximum uptime.
Silver Plated Terminals
LayerZero utilizes silver plating on all input terminals to be able to
provide the highest performance. Silver has high conductivity and low
resistance - which makes for a great contact.

Scan Bolted Connections with Dead-Front Doors Closed
Strategically positioned IR-scan portholes to enable safe thermal
scanning of all bolted connections with the deadfront closed, without
exposing the operator to power circuit voltage.
The IR window swivels upward and unlocks with key-hole access
to reveal a mesh, allowing the operator to point-and-shoot
thermal cameras to obtain accurate readings. LayerZero provides
documentation for proper thermal scanning procedures.
View CB Positions With Dead-Front Doors Closed
The Series 70: eRDP is equipped with polycarbonate windows located
on the outer door of the subfeed circuit breaker section.
Circuit breaker positions can be viewed with the dead-front door
closed.

Guided Wireways
Help keep cables and wiring organized with our guided wireways and
cable clips.
Sectionalization Maximizes Operator Safety
Operators are well-protected from exposed connections. Normal
operator sections (breakers/switches) are physically separated
from the power electronics and control electronics sections, so that
maintenance on a section can be safely performed. If maintenance is
required on a particular section, power can be bypassed to another
section to allow for safe repairs to be made.
After installation, there is no need to open the eRDP left cabinet.

eRDP 1200 A Circuit Breaker Installation Process
The LayerZero SafePanel™
The Series 70 eRDP features an IP-20, finger-safe panel board,
meaning that the opening will not allow ingress of ½” (12.5mm)
diameter probe, for maximum operator safety.
An arc can form as two live conductors are separated – such as
the removal of a circuit breaker from a panel board. The SafePanel
design ensures that a potential arc would be contained in the
connection well so that even if a branch breaker were to be
removed, the arc would be contained in the connection well.
Insulated with the components deeply isolated, removal of the
breaker is safe and easy.

Bluetooth Keeps Circuit Level Information Up-To-Date
Coordinate efforts to keep panel board naming conventions accurate
and up-to-date with Bluetooth connectivity. In critical facilities,
Facilities typically install the physical circuit breakers, while IT workers
manage naming of panel designations.
With Bluetooth connectivity, the naming, size, and assignment of
circuit breakers can be taken care of at the point-of-impact, bringing
together the efforts of facilities and IT for more accurate deployment.
Connectivity Options

The Series 70 eRPP is equipped with Zen DPQM
(Distribution Power Quality Monitoring), an all
encompassing monitoring system with local and
remote communications options.
From basic monitoring & alarm reporting, to advanced
power quality monitoring functionality, Zen DPQM
provides a wide-range of options to help you be aware,
be vigilant, be proactive in your quest to create a safe,
stable and reliable operation.
Zen DPQM Provides Answers
Zen DPQM provides timestamped pictures of waveforms before and after events, providing information that
enables facilities to go back in time to methodically identify and correct the root causes of events. Zen actively
captures power quality information at the STS, PDU, and RPP - permitting thorough post-event analysis.
