Basic Operation
Indicator Lights (Front Panel)
All Indicator Light descriptions apply when the UPS is plugged into a wall outlet and turned ON.
“POWER” LED: This green LED lights continuously when the UPS is ON and
supplying connected equipment with AC power from a utility source. The LED
flashes and an alarm sounds (4 short beeps followed by a pause) to indicate the
UPS is operating from its internal batteries during a blackout or severe brownout.
If the blackout or severe brownout is prolonged, you should save files and shut
down your equipment, since internal battery power will eventually be depleted.
See “BATTERY CHARGE” LED description below.
“VOLTAGE CORRECTION” LED: This green LED lights continuously whenever the
UPS is automatically correcting high or low AC voltage on the utility line without
the assistance of battery power. The UPS will also emit a slight clicking noise.
These are normal, automatic operations of the UPS; no action is required on your
part.
“OUTPUT LOAD LEVEL” LED: This multicolored LED indicates the approximate
electrical load of equipment connected to the UPS’s AC outlets. It will turn from
green (light load) to yellow (medium load) to red (overload). If the LED is red
(either illuminated continuously or flashing), clear the overload immediately by
unplugging some of your equipment from the outlets until the LED changes from
red to yellow (or green). CAUTION! Any overload that is not corrected by the user
immediately may cause the UPS to shut down and cease supplying output power
in the event of a blackout or brownout.
“BATTERY CHARGE” LED: When the UPS is operating from utility power, this LED
indicates the approximate charge state of the UPS’s internal batteries: red
indicates the batteries are beginning to charge, yellow indicates the batteries are
roughly midway through charging, and green indicates the batteries are fully
charged. When the UPS is operating from battery power during a blackout or
severe brownout, this LED indicates the approximate amount of energy
(ultimately affecting runtime) which the UPS’s batteries will provide: red indicates
a low level of energy, yellow indicates a medium level of energy, and green
indicates a high level of energy. Since the runtime performance of all UPS
batteries will gradually deplete over time, it is recommended that you periodically
perform a self-test (see “MUTE/TEST” Button description) to determine the energy
level of your UPS batteries BEFORE a blackout or severe brownout occurs. During
a prolonged blackout or severe brownout, you should save files and shut down
your equipment, since battery power will eventually be depleted. When the LED
turns red and an alarm sounds continuously, it indicates the UPS’s batteries are
nearly out of power and UPS shut down is imminent.
“BATTERY WARNING” LED: This LED lights red and an alarm sounds
intermittently after you complete a self-test (See “MUTE/TEST” Button
description) to indicate the UPS batteries need to be recharged or replaced.
Allow the UPS to recharge continuously for 12 hours, and repeat the self-test. If
the LED continues to light, contact Tripp Lite for service. If your UPS requires
battery replacement, visit tripplite.com to locate the specific Tripp Lite
replacement battery for your UPS.
