Information regarding PE connection

A leakage current > 3.5 mA may be generated when operating the inverter. To avoid shock currents according to EN 61800-5-1, observe the following cable cross sections:

  • Supply system cable < 10 mm2:
  • Route a second PE conductor with the cable cross section of the supply system cable in parallel to the protective earth via separate terminals or use a copper protective earth conductor with a cable cross section of 10 mm2.
  • If an inverter with a metal backplane is located on a grounded mounting plate, it is not necessary to connect a 2nd PE to the inverter. The connection for grounding the mounting plate must be marked as PE connection.
  • If an earth leakage circuit breaker is used for protection against direct and indirect contact, it must be universal current sensitive (RCD type B).
