Frequency converters can cause fault currents that
are not detected by means of a standard soil leakage
circuit breaker. Therefore, the machine may be
operated with an AC/DC sensitive RCCB (residual-
current circuit-breaker) only.
Frequency converters have built-in capacitors that
discharge after switching off the machine. The
machine’s connecting plug may be pulled out of the
outlet not before approx. 1 to 2 minutes after
switching off the main circuit breaker.
