Connecting a 7.5-kW AC Power Supply to AC Power Sources

To connect a 7.5-kW AC power supply to one or more AC power sources, follow these steps:
Ensure that the power supply switch located on the front of the power supply is set at standby (labelled
Step 1
as STBY).
Plug each power cable into one or two AC power sources supplied by the data center.
Step 2
Note If you are using the combined power mode or power supply redundancy, connect both power cables to
the same 30-A circuit. If you are using the input source redundancy mode or full redundancy mode,
connect one power cable to one AC power source and the other cable to another AC power source.
Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018
