NOTE: For high voltage UPSs, the Site Wiring Fault function is disabled by default, but can be manually enabled.

To change the UPS configuration parameters:

1.Place the UPS in Configure mode (on page 41).

The LEDs associated with the currently configured parameters illuminate. A flashing cursor indicates where you are in the configuration process as you scroll through the available settings.

2.Press the On button to scroll through the options. Each time the On button is pressed, the audible alarm sounds.

3.If the On button is pressed and the UPS does not respond, the UPS is in Operate mode (on page 40). Start over with step 1.

4.Press the Off button once to toggle the selected option on or off.

5.Repeat steps 2 and 3 for each option.

6.To save the configuration settings and exit Configure mode, press and hold the Test/Alarm Reset button for 3 seconds.

NOTE: Configure mode times out after 2 minutes of inactivity. If the Test/Alarm Reset button has not been pressed, any new selections are not saved.

For the location of buttons, see "UPS front panel controls (on page 8)."

For the location of LEDs, see "UPS front panel LED indicators (on page 8)."

Initiating a self-test

To initiate a self-test, press and hold the Test/Alarm Reset button ("UPS front panel controls" on page 8) for three seconds.

If the UPS detects a problem, the appropriate LED ("UPS front panel LED indicators" on page 8) illuminates and an audible alarm may sound.

For information on what to do if the self-test detects a problem, see "Troubleshooting (on page 55)."
