 Install earth−leakage circuit breakers only
between the supply mains and the frequency
inverter.
 The earth−leakage circuit breaker may trip
incorrectly if several drives are
simultaneously connected to the mains.

Relay data
NOTE
The service life of the relay depends on the
type of load (ohmic, inductive or capacitive)
and the value of the switching capacity.
