Basic Operation
OFF ON
Switches
With your UPS plugged in, set this switch according to the
recommendations in Step 3 of the Quick Installation section.
“ON” Position
Function: ENABLES battery backup. UPS Conditions: The UPS
battery is charging. Power is ON at the UPS receptacles. The “
”
indicator light is illuminated. Setting Advantages: Provides
battery backup during blackouts or brownouts.
“OFF” Position
Function: DISABLES battery backup. UPS Conditions: The UPS
battery is charging. Power is ON at the UPS receptacles. The “ ”
indicator light is illuminated. The “
” indicator light is flashing.
Setting Advantages: Continues to charge the battery when
power is present while turning OFF the inverter to prevent battery
backup operation when equipment is not in use.
Use this momentary switch to do three things:
Silence the UPS On-Battery alarm
Move this switch to the left and release it to silence the UPS On-
Battery alarm, a series of short beeps followed by a brief pause
that is activated when the UPS is providing AC power from battery.
Note: When the battery is nearly depleted, the Low Battery
alarm—a continuous beep that cannot be silenced—will alert you
to immediately shut down connected equipment.
Test your UPS's battery charge
Leave your connected equipment ON. With your UPS plugged in
and turned ON, move this switch to the left, hold it there for 2
seconds and release it. The UPS will emit several short beeps as
it momentarily switches to battery to test its charge. If the UPS
low battery alarm sounds (a long, continuous beep) or the
properly-sized load is not supported, let your UPS charge its
batteries for 12 hours and repeat the test. If the long, continuous
alarm still sounds, contact Tripp Lite for service. CAUTION: Do
not unplug your UPS to test its batteries. This will remove safe
electrical grounding and may introduce a damaging surge into
your network connections.
Cold-Start your UPS
You may “cold start” your UPS and use it as a stand-alone power
source when utility power is not present, providing that the UPS's
battery is charged. To “cold start” your UPS, first turn the “OFF/
ON” switch ON. Then, move the “MUTE/TEST” switch to the left,
hold momentarily and release when the “
” indicator light
begins to flash.
