"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 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 "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. 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. If your UPS requires battery replacement, visit
tripplite.com/support/battery/ index.cfm to locate the specific Tripp Lite
replacement battery for your UPS.
* The alarm will beep once briefly after the indicated interval has passed.
