A "Input Voltage" Meter: This meter measures, in real time, the AC voltage that the UPS
system is receiving from the utility wall outlet. Although the meter may occasionally display
input voltages which stray outside the range of standard computer tolerance (due to poor
quality utility service), rest assured that the UPS is designed (through the use of automatic
voltage regulation) to continuously supply connected equipment with stable, computer-grade
output voltage. In the event of a blackout (power loss), severe brownout (low power) or
overvoltage (high power), the UPS will rely on its internal battery to supply computer-grade
output voltage.
B "BATTERY CAPACITY" Meter: This meter displays the approximate charge level (in 20%
increments) of the UPS's internal battery. During a blackout or severe brownout, the UPS will
switch to battery power, the "ON BAT" icon will be illuminated and the charge level will
deplete.
C
"AVR" (Automatic Voltage Regulation) Icon: This icon will illuminate whenever your UPS is
automatically correcting AC line voltage without depleting battery power. This is a normal,
automatic operation of your UPS, and no action is required on your part.
D
"REPLACE" (Battery Recharge/Replace) Icon: This icon will illuminate and an alarm will
sound after a self-test to indicate the UPS battery needs 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, contact Tripp Lite for service. Battery replacement should only be
performed by qualified service personnel.
E
"ON BAT" (On Battery) Icon: During a severe brownout or blackout, this icon illuminates
and an alarm sounds (4 short beeps followed by a pause) to indicate the UPS is operating
from its internal batteries. Monitor the "Battery Capacity" Meter to determine the
approximate battery charge level available to support equipment. During a prolonged
brownout or blackout, the alarm will sound continuously (and the "BATTERY CAPACITY"
Meter will show one 20% capacity segment shaded) to indicate the UPS's batteries are
nearly out of power; you should save files and shut down your equipment immediately.
F
"FAULT" Icon: This icon will illuminate and an alarm will sound after a self-test to indicate
the battery-supported outlets are overloaded. To clear the overload, unplug some of your
equipment from the battery-supported outlets and run the self-test until the icon is no longer
illuminated 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.

LCD Dimmer: Adjusts the brightness of the LCD Status Screen.

LCD Status Screen
The LCD Status Screen indicates a variety of
UPS operational conditions. All descriptions
apply when the UPS is plugged into an AC
outlet and turned on.
Note: The LCD will illuminate for 1 second when the
UPS is plugged in, before it is turned on. The LCD
Status Screen can be rotated for easy viewing,
regardless of whether the UPS is in a horizontal or
vertical position. To rotate the LCD Status Screen,
insert a small tool in the slots on the sides of the
screen to pop it out of the UPS housing; rotate the
screen, and snap it back into the UPS housing.
