Configuration

Setting and connection example
The appropriate configuration of the output contact matrix enables using the start
signals of the earth-fault current and voltage units as contact functions. The start
signals can be used for blocking co-operating protection relays, for signalling and
for initiating autoreclosing.
Fig. 3.3.-1 represents the relay with the default configuration: all trips are routed to
operate the circuit breaker.
