When using earth−leakage circuit breakers, observe the following:
ƒ
Only install the earth−leakage circuit breaker between supplying mains and drive
controller.
ƒ
Earth−leakage circuit breakers can trip incorrectly due to
– capacitive compensation currents flowing in the cable shields during operation
(particularly with long, shielded motor cables),
– simultaneous connection of several inverters to the mains
– the use of additional interference filters.
