Basic Operation
“ON/OFF” Button
• To Turn the UPS ON: Press and hold the ON/OFF button for one second.* If
utility power is absent, pressing the button will “cold-start” the UPS, i.e. turn it
on and supply power from its battery.**
• To Turn the UPS OFF: Press and hold the ON/OFF button for one second.* The
UPS will be turned completely off (deactivated).
* The alarm will beep once briefly after one second has passed. ** Runtime will be
proportionate to the UPS battery’s level of charge.
“MUTE/TEST” Button
• To Silence (or “Mute”) UPS Alarms: Briefly press and release the MUTE/TEST
button.
Note: Continuous alarms (warning you to shut down connected equipment immediately)
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 Self-
Test” below.
Note: You can leave connected equipment on during a self-test.
CAUTION! Do not unplug your UPS to test its battery. 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 charge. All LCD screen icons will be
illuminated and the UPS alarm will sound.
• If the “FAULT” icon remains lit and the alarm continues to sound after the test,
the battery-supported outlets are overloaded. To clear the overload, unplug some
of your equipment from the battery-supported outlets and repeat the self-test
until the “FAULT” icon is no longer lit and the alarm is no longer sounding.
Note: The alarm beeps once per minute.
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 “REPLACE” icon 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 24 hours, and repeat the self-test. If the icon
continues to illuminate after repeated self tests, contact Tripp Lite for service.
Battery replacement should only be performed by qualified service personnel. If
the UPS requires battery replacement, Tripp Lite offers a complete line of
replacement batteries at www.tripplite.com.
Note: The alarm beeps once per minute.
