Chapter 5 – Commissioning the Drive SectionACS 600 MultiDrive 5-3Connecting Voltage toAuxiliary CircuitsThe table below describes how to connect voltage to the SupplySection input terminals and to the Auxiliary Control Unit (ACU) for thefirst time.Action InformationWARNING! 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 whilethe voltage is connected:• Nobody is working on the unit or circuits that are wired from outside into thecabinets.• The cabinet doors are closed.Disconnect the 230 VAC cables that lead from the terminalblocks to the outside of the equipment and have not yetbeen checked, and the connections which may not yet havebeen completed.Disconnect the communication link to the overriding systemby removing the fiber optic cables.See the circuit diagramsdelivered with the device.Make sure that the main contactor/air circuit breaker cannotbe closed inadvertently by remote control, e.g. bytemporarily opening a connection in its control circuit.Be ready to trip the main breaker of the supply transformerin case something abnormal occurs.Ensure that all cabinet doors are closed.Close the main breaker of the supply transformer.Frame sizes B1, B2, B3 and B4 type ACA 631-0850-61-xx:Close the main disconnecting switch of the Supply Section.~=~ =~=Auxiliaryvoltage
