Basic Operation
“ON/TEST” Switch:
This switch controls four separate UPS functions:
UPS Power ON
To turn the UPS on, press this switch, hold it for several seconds until
you hear a beep, then release it. The “ON LINE” LED will illuminate.
UPS Self-Test
During normal on-line operation, press this switch and hold it until you
hear a beep. This initiates a 10-second self-test of the battery. The UPS
will shift to battery power (the “ON BATT” and “BATT ACTIVE METER”
LEDs will illuminate) for ten seconds.
Alarm Silence
To silence the UPS “on-battery” alarm, press this switch and hold it until
you hear a beep.
UPS Cold Start
To use your UPS as a stand-alone power source when AC power is
unavailable (i.e. during a blackout), press this switch and hold it until
you hear a beep. The UPS will then provide battery power to its out-
lets.*
* The “ON BATT” Indicator Light will be illuminated since your UPS will be operating from battery power.
“OFF” Switch:
This switch turns power OFF at the UPS receptacles.
Press this switch, hold it until you hear a beep, then release it. The UPS
will continue charging and the fan will continue to cool internal com-
ponents even after you turn the UPS receptacles off. To turn the UPS
OFF completely, including the charger, disconnect the UPS’s power cord
after pressing the “OFF” switch.
“ON LINE” LED:
This green light will illuminate constantly to indicate
the UPS is performing normal on-line operation (filtering and resyn-
thesizing incoming AC line voltage to provide pure sine wave output).
When this light is illuminated, you can monitor the load level of your
UPS on the “LOAD ACTIVE METER” LEDs.
“LINE” LED:
This green light will illuminate constantly to indicate the
utility supplied AC line voltage at your wall outlet is nominal. It will
flash if the line voltage is outside the nominal range (either too low or
two high). No action is required on your part when the LED flashes; the
UPS continuously and automatically filters AC line power to provide
your equipment with pure sine wave AC power, regardless of brownout
or overvoltage conditions. If this light is off, then AC line voltage is not
present (blackout) or is at an extremely high voltage, and the UPS will
provide connected equipment with power from battery.
