Initiating a Self-test

To initiate a self-test, press the TEST/ALARM RESET button and hold for

three seconds. The UPS acknowledges compliance with five beeps.

IMPORTANT:

A portion of the self-test requires battery power; the self-test cannot be

initiated if the batteries are less than 90% charged.

During the self-test, it is normal for the UPS to turn on individual LEDs

momentarily; however, if an alarm condition is detected, the UPS will turn on

the appropriate LED and may sound an audio alarm.

WARNING:

To reduce the risk of electric shock from earth conductor leakage

current, use the self-test procedure to check the UPS batteries (rather than

unplugging the UPS).

■

For the meaning of individual LEDs, see “Front Panel LEDs in the

Standby and Operate Modes,” in this chapter.

For information on what to do if the self-test detects a problem, see

Chapter 6, “Troubleshooting.”
