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 eventual-
ly 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 (ulti-
mately 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 bat-
teries 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 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 con-
tinues to light, contact Tripp Lite for service. If your UPS requires battery
replacement, visit www.tripplite.com to locate the specific Tripp Lite replace-
ment battery for your UPS.
