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: Provides bat- tery 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.

Note: Only UPS models equipped with a “MUTE/TEST” switch allow you to “cold start” them and use them as stand-alone power sources when utility power is not present. To “cold start” your UPS, first turn your UPS ON. Then, move the MUTE/TEST switch to the left, hold momentarily and release when the "" indicator light begins to flash.

Use this momentary switch to do two 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.

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.

*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.

NORM

Available on select models

If you experience severe brownouts that cause the UPS to fre- quently switch to battery, the adjustable voltage potentiometer allows you to prevent excessive battery drain by lowering the voltage point at which the UPS switches to battery. Turn it clockwise to lower the voltage point as much as 18% below the nominal setting of 99 volts (set fully clockwise).

Note: Your UPS’s optimal setting will depend on the voltage conditions in your area. Adjust it clockwise until you reduce the frequency your UPS switches to battery. Your UPS will function properly at any setting. Use caution when adjusting the potentiometer while the UPS is powering voltage-sensitive loads.
