NOTE: If present, power the undervoltage coil in advance.
1. Power the undervoltage coil at the relevant rated voltage and perform the closing
operation on the circuit-breaker.
Result: The circuit-breaker closes correctly; the signals are normal.
2. Turn off the voltage supply to the trip unit. The circuit-breaker opens.
3. Power the undervoltage coil at the relevant rated voltage and perform the closing
operation on the circuit-breaker.
Undervoltage coil
Result: The circuit-breaker closes; the signal switches over.
WARNING! If the undervoltage coil has been tripped by a power failure,
the circuit-breaker can be closed only after the coil has been energized
electrically. Make sure that the coil has effectively been tripped due to a
power failure. Otherwise, examine the circuit-breaker and the
associated equipment to make sure that they are in a good condition.
