PHASE CHECK

After all hardwired connections are complete (including external battery cabinets, if applicable), complete the phase check using the following steps. You will need an AC voltmeter for the phase check.

C A U T I O N

Before operating the bypass switch, use the following procedure to check the wiring for correct installation. To prevent damage to the load, turn off the main circuit breaker in the load service panel or verify that the load cannot receive power from the UPS.

Confirm that an electrician has completed and tested the connection to the proper power source.

Verify that the bypass switch is in the OFF position.

At the UPS AC input service panel, turn on the input power to the UPS and the bypass switch.

Turn on the AC disconnect switch.

The AC LINE indicator on the UPS illuminates.

NOTE The AC LINE indicator does not illuminate for FE models with serial numbers 25000 and greater until the UPS ON/OFF switch is turned to the ON position.

If your UPS has a DC switch, turn on the switch according to the UPS model:

500 VA–3.1 kVA: Most units do not have a DC switch on the UPS or external battery cabinet(s). If the external battery cabinet has a DC switch, turn the switch to the ON position.

4.3–7 kVA: If you have an external battery cabinet(s) with a DC switch, turn the switch to the ON position.

If you do not have an external battery cabinet(s): unlock the UPS front cover panel using the FERRUPS key and remove the front cover panel. Locate the DC switch behind the UPS front cover panel. If there is a precharge button next to the switch, press it for a few seconds. Turn the DC switch to the ON position and reinstall the UPS front cover panel.
