Indicator Lights
All Indicator Light descriptions apply when the UPS is plugged into an AC outlet and turned on.
LINE POWER: This green light will illuminate whenever the UPS is ON
and receiving normal AC line power.
BATTERY POWER: This yellow light will illuminate when the UPS is
providing equipment with battery power.
REPLACE BATTERY: This red light will illuminate continuously after
the UPS runs a self-test to indicate that the battery is weak. If it remains lit
after allowing the UPS to charge for twelve hours and running a second
self-test, contact Tripp Lite for service.
OVERLOAD: This red light will illuminate continuously to indicate that
the UPS is overloaded when the UPS is providing power from battery or
after the UPS runs a self-test. If it lights up, immediately remove some of
the equipment connected to the "UPS/Surge" outlets and run a self-test.
Large overloads may cause the UPS to shut down.

"UPS/Surge" outlets and run the self-test again. If the batteries are
weak, the " " LED will stay lit and the UPS will continue to beep
after the test. If this happens, let the UPS charge its batteries for 12
hours and repeat the test. If the condition persists, contact Tripp Lite
for service. CAUTION: Do not unplug the UPS to test its batteries.
This will remove safe electrical grounding and may introduce a
damaging surge into network connections.
