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 illuminates 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, save all files and shut down
equipment, as the internal battery power will eventually be depleted. See
“BATTERY CHARGE” LED description below.
“VOLTAGE CORRECTION” LED
This green LED illuminates 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.
“OUTPUT LOAD LEVEL” LED
This multicolored LED indicates the approximate electrical load of equipment
connected to the UPS 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 equipment from
the outlets until the LED changes from red to yellow (or green) and the alarm
is no longer sounding. CAUTION! Any overload 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 system’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) the UPS 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 to 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, save all files and shut down equipment, as battery
power will eventually be depleted. When the LED turns red and an alarm sounds
continuously, it indicates the UPS batteries are nearly out of power and shut down
is imminent.
“BATTERY WARNING” LED
This LED illuminates red and an alarm sounds intermittently after initiating 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 the UPS requires battery replacement, visit
www.tripplite.com/products/battery-finder/ to locate the UPS system’s
appropriate Tripp Lite replacement battery.
