Basic Operation continued

“MUTE/TEST” Button

•To Silence (or “Mute”) UPS Alarms: briefly press and release the MUTE/TEST button.

•To Run a Self-Test: with your UPS plugged in and turned ON, press and hold the MUTE/TEST button for two seconds.* Continue holding the button until the alarm beeps several times and the UPS performs a self test. See “Results of a Self-Test” below. Note: you can leave connected equipment on during a self-test. Your UPS, however, will not perform a self-test if the UPS is not turned on (see “ON/OFF/STANDBY” Button description).

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.

Results of a Self-Test: the test will last approximately 10 seconds as the UPS switches to battery to test its load capacity and battery charge.

•If the “OUTPUT LOAD LEVEL” LED remains lit red and the alarm continues to sound after the test, the UPS’s outlets are overloaded. To clear the overload, unplug some of your equipment and run the self-test repeatedly until the “OUTPUT LOAD LEVEL” LED is no longer lit red and the alarm is no longer sounding.

CAUTION! Any overload that is not corrected by the user immediately following a self-test may cause the UPS to shut down and cease supplying output power in the event of a blackout or brownout.

•If the “BATTERY WARNING” LED remains lit and the alarm con- tinues to sound after the test, the UPS batteries need to be recharged or replaced. Allow the UPS to recharge continuously for 12 hours, and repeat the self-test. If the LED remains lit, contact Tripp Lite for service. If your UPS requires battery replacement, visit www.tripplite.com to locate the specific Tripp Lite replacement bat- tery for your UPS.

* The alarm will beep once briefly after the indicated interval has passed.

Indicator Lights (Front Panel)

All Indicator Light descriptions apply when the UPS is plugged into a wall outlet and turned ON.

“POWER” LED: this green LED lights continuously when the UPS is ON and supplying connected equipment with AC power from a utility source. The LED flashes and an alarm sounds (4 short beeps followed by a pause) to indicate the UPS is operating from its internal batteries dur- ing a blackout or severe brownout. If the blackout or severe brownout is prolonged, you should save files and shut down your equipment since internal battery power will eventually be depleted. See “BATTERY CHARGE” LED description below.
