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 alarm*
Move this switch to the left and release it. Note: When the battery
is nearly depleted the alarm resumes (and cannot be silenced) to
alert you to immediately shut down connected equipment.
*The UPS alarm consists of a series of short beeps followed by a brief pause. The alarm is activated when
the UPS switches to battery during a blackout or brownout.
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 momentarily switch to
battery to test its charge. If the UPS alarm sounds or the properly-
sized load is not supported, let your UPS charge its batteries for
12 hours and repeat the test. If 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.
**If your model is not equipped with this switch, you can still test your UPS batteries. First plug your UPS
into a grounded surge suppressor (which will maintain the ground connection), then turn the surge
suppressor's power switch OFF.
Cold-Start your UPS
If your UPS is equipped with a MUTE/TEST switch, you may “cold
start” it 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.
