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) and the alarm is no longer
sounding. 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 severe 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 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/support/battery/index.cfm to locate the specific
Tripp Lite replacement battery for your UPS.
