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.
