American Power Conversion InfraStruXureTM System manual Apply power to the system

Start-Up Procedure: InfraStruXure System

Apply power to the system

1.Set the upstream main (and bypass, if applicable) utility circuit breaker to ON.

2.Ensure A-B-C clockwise phase rotation at the top of the Main Input (A) switch on the PDU, using a phase rotation meter.

3.Set the Main Input (A) switch on the PDU to ON.

4.Verify A-B-C 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 (208V, metered phase-to-phase), using a true RMS voltmeter.

6.Install at least one battery module (four battery units) in the Battery Enclosure.

Install battery modules, starting in the lowest available shelf. Position the battery unit between the grooves, and slide it completely into the enclosure.

Heavy

Electrical Hazard

Use two people to lift and install battery units.

The DC bus in the Battery Enclosure is energized when battery modules are installed, even when the DC Disconnect breaker is open.
