Connecting Voltage To Auxiliary Circuits - ABB ACA 6 Series Hardware Manual

Connecting Voltage to
Auxiliary Circuits
WARNING! When voltage is connected to the input terminals of the Supply Section,
the voltage will also be connected to the Auxiliary Control Unit and to auxiliary circuits
- also to the ones wired to drive sections.
Make sure that it is safe to connect voltage to the input terminals. Ensure that while
the voltage is connected:
• Nobody is working on the unit or circuits that are wired from outside into the
cabinets.
• The cabinet doors are closed.
Disconnect the 230 VAC cables that lead from the terminal
blocks to the outside of the equipment and have not yet
been checked, and the connections which may not yet have
been completed.
Disconnect the communication link to the overriding system
by removing the fiber optic cables.
Make sure that the main contactor/air circuit breaker cannot
be closed inadvertently by remote control, e.g. by
temporarily opening a connection in its control circuit.
Be ready to trip the main breaker of the supply transformer
in case something abnormal occurs.
Ensure that all cabinet doors are closed.
Close the main breaker of the supply transformer.
