Adjust the DIP switchaccording to requirements. Refer below image. SAFETY INSTRUCTIONS Installation should only be performed by qualified professionals according to the laws and regulations. Do not connect the mains voltage nor any other external voltage to any point of the Modbus connector; it would represent a risk for the entire system. The facility must have enough insulation between the mains (or auxiliary) voltage and the Modbus or the wires of other accessories, in case of being installed. Keep the device away from water and do not cover it with clothes, paper or any other material while in use.
