Start-Up Procedure

56 InfraStruXure System – Service Manual – Installation and Start-Up 990-1467C

Verify proper voltage and phase rotation on the PDU

1. Close (turn ON) the Q1 circuit breaker on the InfraStruXure PDU to apply power to the UPS.

2. Ensure A-B-C clockwise rotation at the UPS input bus bars, using a phase rotation meter.

3. Verify proper voltage is present at the UPS input bus bars (208V, metered phase-to-phase),

using a true RMS voltmeter.

4. Ensure A-B-C clockwise rotation at the top of the PDU bypass switch, using a phase rotation

meter.

5. Verify proper voltage is present at the top of the PDU bypass switch (208V, metered phase-to-

phase), using a true RMS voltmeter.

Warning: The voltage for the bypass feed can only be 208V, phase-to-phase.

2. Set the UPS System Enable switch to the

OFF position.

3. Set the XR Battery Enclosure DC Disconnect

circuit breaker to the OFF position.
