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 prevent 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 the section, “Front Panel Controls and LED
Indicators,” in this chapter.
• For information on what to do if the self-test detects a problem, refer to the section,
“Alarm Troubleshooting,” in Chapter 5.
