IMPORTANT: A portion of the self-test requires battery power; the self-test cannot be
initiated if the batteries are less than 90 percent 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 appropriate UPS
LED will illuminate and an audio alarm may sound.
WARNING: To reduce the risk of electric shock from Earth (ground) 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."
