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" LEDs: the LEDs indicate the approximate
electrical load of equipment connected to the UPS's AC outlets. They 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" LEDs: when the UPS is operating from utility power,
the LEDs indicate 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, the LEDs indicate 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 red LED illuminates and an alarm sounds continuously, it
indicates the UPS's batteries are nearly out of power and UPS shutdown is
imminent.
"BATTERY WARNING" LED: this LED lights red and an alarm sounds
intermittently after you initiate 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 www.tripplite.com to locate the specific Tripp Lite
replacement battery for your UPS.
