Basic Operation
Indicator Lights
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" LEDs: These multicolored LEDs indicate
the approximate electrical load of equipment connected to the UPS outlets:
green (light load), yellow (medium load) and red (overload). If the red LED
is either illuminated continuously or flashing, clear the overload
immediately by unplugging some of your equipment from the outlets until
the yellow or green LED illuminates. 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" LEDs: When the UPS is operating from utility
power, these LEDs indicates the approximate charge state of the UPS
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, these multicolor
LEDs indicate the approximate amount of energy (ultimately affecting
runtime) that 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 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 red LED illuminates and an alarm
sounds continuously, this indicates that the UPS batteries are nearly out of
power and UPS shutdown is imminent.
"BATTERY WARNING" LED: this LED lights yellow 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.

"SITE WIRING FAULT" LED: This yellow LED will be lit if the UPS
detects a problem with the wiring of the AC outlet you connect it to. If this
occurs, have the outlet inspected by a qualified electrician. Note that while
the UPS will detect many common wiring faults, including a missing
ground, reversed polarity and overloaded neutral circuits, it cannot detect
every conceivable wiring problem.
