Basic Operation continued

Indicator Lights

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 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, 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 illuminate whenever your UPS

is receiving normal AC line power. It will ﬂash while the UPS is in CHARGE ONLY

mode to indicate the UPS will not provide battery backup during a blackout or

brownout.

“VOLTAGE CORRECTION” LED (For Select Smart and OmniSmart Models):

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 on your part.

“OUTPUT LOAD LEVEL” LED (For Select Smart and OmniSmart Models):

For SmartPro Models Only: This multicolored LED indicates the approximate

electrical load of equipment connected to the UPS system’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 illuminate continuously when the

UPS is providing power from battery or after the UPS runs a self-test to indicate

that the 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 supplying output power in the event of a blackout or

severe brownout.
