Because a portion of the self-test requires battery power, the self-test cannot be initiated if the
batteries are less than 90 percent charged. If the UPS detects a problem, the appropriate LED
illuminates and an audible 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, refer to “Front Panel Controls and LED Indicators,”
in this chapter.
• For information on what to do if the self-test detects a problem, refer to Chapter 5,
“Troubleshooting.”
