Main breaker/contactor
Charging contactor
1) Not in use as default.
For details, see the delivery-specific
circuit diagrams of the drive.
diagrams show:
- supply unit on/off control
- main breaker supervision and on/off
control
- charging contactor on/off control
- optional auxiliary circuit wiring.
WARNING! Starting sequence ie,
charging, acknowledgements, main
breaker/contactor control and the
supply unit start, follows a certain order.
Never change the order by by-passing
signals (using jumpers), etc. That will
cause a malfunction that may damage
the unit.
