“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 you have placed it in “Standby/Charge-Only” mode (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. All
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 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/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.
All Indicator Light descriptions apply when the UPS is plugged into a wall outlet and turned ON.
“POWER” LED:
this green LED lights continuously when the UPS is ON
and supplying connected equipment with AC power from a utility source.
The LED flashes and an alarm sounds (4 short beeps followed by a pause)
to indicate the UPS is operating from its internal batteries during a blackout
or severe brownout. If the blackout or severe brownout is prolonged, you
should save files and shut down your equipment since internal battery power
will eventually be depleted. See “BATTERY CHARGE" LED description
below.
“VOLTAGE CORRECTION” LED:
this green LED lights continuously
whenever the UPS is automatically correcting high or low AC voltage on the
utility line without the assistance of battery power. The UPS will also emit
a slight clicking noise. These are normal, automatic operations of the UPS,
no action is required on your part.
