Leakage currents
Earth-leakage currents ≥ 3.5 mA can occur during normal operation. In order to fulfill
EN 61800-5-1, observe the following notes:
•
The protective earth (PE) connection must meet the requirements for systems with
high earth-leakage currents.
•
This usually means
– installing a PE connection cable with a minimum cross section of 10 mm
2
(cop-
per conductor)
– or installing a second PE connection cable in parallel with the original PE con-
nection.
The second PE connection is not required according to DIN EN 61800-5-1, 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 diameter of
≥
2.5 mm
2
.
INFORMATION
The round M23 plug connectors of the 723 series by TE Connectivity - Intercontec
products meet the requirements according to IEC 60309 "Plug connectors for indus-
trial applications".
