Indicator Lights

All Indicator Light descriptions apply when the UPS is plugged into an AC outlet and turned on.
"POWER" LED
For SMX Models Only: 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 inter-
nal 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 deplet-
ed. See "BATTERY CHARGE" LED description below.
For OMNIX Models Only: this green light will turn ON whenever
your UPS is receiving normal AC line power. It will flash while the
UPS is in CHARGE ONLY mode to indicate that the UPS will not
provide battery backup during a blackout or brownout.
"VOLTAGE CORRECTION" LED (SMX Models Only): this
green LED lights continuously whenever the UPS is automatically
correcting high or low AC voltage on the utility line without the assis-
tance 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:
For SMX Models Only: this multicolored LED indicates the approx-
imate 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 flash-
ing), 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 over-
load 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 black-
out or severe brownout.
For OMNIX Models Only: this red light will turn ON continuously
when the UPS is providing power from battery or after the UPS runs
a self-test to indicate that the UPS's inverter is overloaded. If it lights
up, immediately remove some of the equipment connected to the UPS
and run a self-test. CAUTION! Any overload that is not corrected by
the user immediately may cause the UPS to shut down and cease sup-
plying output power in the event of a blackout or severe brownout.
