Description
The setpoint is used for adjusting the behavior of the Neutral CB C/O output
according to actual site wiring.
The neutral contactor is used to connect the neutral wire (N) with the protective
wire (PE) in a TN-S system. This connection must exist in one moment at one
point of the circuit only.
The EACH option should be used if each gen-set has it's own neutral contactor.
Four-pole GCB must be used for this case.
 The output is always opened while the gen-set is not running.
 The output is always opened while the MCB is closed.
 While the gen-set is running and GCB is open, the output closes when
