All Indicator Light descriptions apply when the UPS is plugged into an AC outlet and turned on.
“POWER” LED
For SmartPro 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 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.
For OmniSmart Models Only: this green light will turn ON whenev-
er 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 (For Select SmartPro and
OmniSmart Models): 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 (For Select SmartPro and
OmniSmart Models):
For SmartPro Models Only: 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.
For OmniSmart 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. Large overloads may cause your UPS to shut down.
