Indicator Lights (Front Panel)
All Indicator Light descriptions apply when the UPS is plugged into a wall outlet
and turned ON.
POWER: Lights green when the UPS is receiving AC power. Illuminates con-
stantly when the UPS is in the ON mode, indicating that batteries are charging
and connected equipment is receiving filtered AC power. Flashes while in
STANDBY mode to indicate that batteries are charging but connected equip-
ment is not receiving power.
VOLTAGE CORRECTION: Lights green whenever your UPS is automatically
correcting high or low AC line voltage. The UPS will also click gently. These
are normal, automatic operations of your UPS, and no action is required on your part.
BATTERY CHARGE: This multicolored light displays 7 separate UPS battery
charge conditions. It will turn from red (low) to yellow (medium) to green (full)
to show you the level of battery charge. If the light is constant, your UPS is in
the ON or STANDBY mode, operating from line power, and the battery is
charging. If the light is flashing, your UPS is in the INVERT mode, operating
from battery, and the battery is discharging. If the light is flashing red, your UPS
is in INVERT and is nearly out of power: you should save files and shut down
your equipment immediately.
OUTPUT LOAD: This multicolored light shows how heavy your UPS's load
is. Steady green indicates a light load, steady yellow a medium load. When the
light is red, your UPS is supporting a load above 85% of its capacity. If the red
light begins flashing, then your UPS is severely overloaded. Immediately
remove load from the UPS until the light stops flashing.
BATTERY WARNING: Lights red if your UPS's self-test (initiated with the
Mute/Test Switch) reveals a low battery charge or internal fault. If this light
turns on, let the UPS charge for 12 hours then perform a second self-test. If the
light stays on, contact Tripp Lite for service.
