Front Panel Switches
“ON/TEST” Button:
This switch controls four separate UPS functions:
UPS Power ON
To turn the UPS on, press this button, 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 button 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 (all LEDs will illuminate) for ten
seconds.
Alarm Silence
To silence the UPS “on-battery” alarm, press this button 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 button and hold it until
you hear a beep. The UPS will then provide battery power to its outlets.*
* The “ON BATT” Indicator Light will be illuminated since your UPS will be operating
from battery power.
“OFF” Button:
This button 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
components 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
resynthesizing 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.
