Basic Operation
Buttons
“POWER” Button:
• To turn the UPS ON: With the UPS plugged into a live AC wall outlet,* press
and hold the POWER button for one second.** Release the button. 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. *** Fully charged batteries are recommended.
“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.* The alarm will beep once. Release the
button, and the UPS will perform 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 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.** 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. If your UPS requires battery
replacement, visit www.tripplite.com/products/battery-finder to locate the specific
Tripp Lite replacement battery for your UPS.
* The alarm will beep once briefly after the indicated interval has passed. ** The “POWER”
LED will be flashing and the “OUTPUT LOAD LEVEL” and “BATTERY CHARGE” LEDs will be lit
and the UPS alarm will sound.
