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 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.
