APC Power Supply manual Apply power to the system

Start-Up Procedure: InfraStruXure System

Apply power to the system

1.Set the upstream input circuit breaker (utility or UPS) to ON.

2.Ensure R-S-T clockwise phase rotation at the top of the main input switch on the PDU, using a phase rotation meter.

3.Close (turn ON) the main input switch on the PDU.

4.Verify R-S-T clockwise phase rotation at the top of the primary winding of the transformer, using a phase rotation meter.

5.Verify that the proper voltage is present on the secondary winding of the transformer (200 or 173V, metered phase-to-phase), using a true RMS voltmeter.
