Basic Operation
For All Models—"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 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.
* The alarm will beep once briefly after the indicated interval has passed. ** SmartPro models'
operation during the self-test: the "POWER" LED will be flashing and the "OUTPUT LOAD
LEVEL" and "BATTERY CHARGE" LEDs will be lit and the UPS alarm will sound. OmniSmart
models' operation during the self-test: all LEDs will be lit and the UPS alarm will sound.
continued
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 imme-
diately following a self-test may cause the UPS to shutdown 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/sup-
port/battery/index.cfm to locate the specific Tripp Lite replacement
battery for your UPS.
