Leakage currents

During normal operation, leakage currents ≥ 3.5 mA may occur. In order to fulfill EN 61800-5-1, observe the following information:

  • The ground connection (PE) must be installed in such a way that it meets the requirements for systems with high leakage currents.
  • This usually means
    • installing a PE connection cable with a minimum cross section of 10 mm2 (copper conductor)
    • or installing a second PE connection cable in parallel to the protective earth.
    • According to DIN EN 61800-5-1, the second PE connection is not required if the line connection is equipped with a plug connector for industrial applications (according to IEC 60309) and if the supply system cable has a cross section of  2.5 mm2.

INFORMATION

According to the IEC 60309-1 standard > chapter "General requirements for connectors, sockets and couplings for industrial applications", the M23 circular plug connectors from TE Connectivity - Intercontec products of the 723 series comply with plug connectors for industrial applications.
