Tripp Lite OmniPro500 Basic Operation, Switches, Silence the UPS On-Battery alarm, ON Position

Basic Operation

Switches

OFF ON

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: UPS provides AC power from battery during power failures.

"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: UPS does not provide AC power from battery during power outages, conserving battery power 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 connected to AC power 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 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

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.
