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.”
