Electrical Connections
The unit is supplied with a 63 Amp miniature circuit breaker that provides overload
and short circuit protection for the unit.
The transformer is fitted with an embedded thermal switch. Should the temperature
of the transformer increase beyond acceptable levels the thermal switch will operate
and automatically shut off the supply to the transformer by ‘tripping’ the incoming
MCB (CP1). Once the transformer temperature has returned to an acceptable level
the thermal switch will reset and the MCB can be closed.
The user wiring connections are indicated in the diagrams below:
On completion of installation the tightness of all electrical connections should
be checked.
