Basic Operation
Indicator Lights
All Indicator Light descriptions apply when the UPS is plugged into an AC 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 / BATTERY POWER” LED: When the UPS is operating from
utility power, this multicolored 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) that 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.
Because runtime performance of all UPS batteries will gradually deplete over
time, it is recommended 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 because 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
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/products/battery-finder to locate the specific Tripp Lite
replacement battery for your UPS.
