If utility power is absent, you can "cold-start" the UPS (i.e.: turn it ON and supply power for a limited time from its batteries***) by pressing and holding the POWER button for about two seconds.** • To turn the UPS OFF: with the UPS ON and receiving utility power, press and hold the POWER button for one second.** Then unplug the UPS from the wall outlet. The UPS will be completely OFF. * After you plug the UPS into a live AC outlet, the UPS will automatically charge its batteries, but will not supply power to its outlets until it is turned ON. ** The alarm will beep once briefly after the indicated interval has passed. *** If fully charged. "MUTE/TEST" Button • To Silence (or "Mute") UPS Alarms: briefly press and release the MUTE/TEST button.* Note: continuous alarms (warning you to immediately shut down connected equipment) cannot be silenced. • 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 SelfTest" below. Note: you can leave connected equipment on during a self-test. Your UPS, however, will not perform a self-test if it is not turned ON (see "POWER" 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. The "POWER" LED will be flashing and the "OUTPUT LOAD LEVEL" and "BATTERY CHARGE" LEDs will be lit and the UPS alarm will sound. • 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 severe brownout. • If the "BATTERY WARNING" LED remains lit and the alarm continues 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.
