Indicator Lights
All Indicator Light descriptions apply when the UPS is plugged into a wall outlet and turned on.
This green light will turn ON whenever your UPS is plugged in and
receiving normal AC line power.
This red light will turn ON when your UPS is providing your equipment
with battery power.
This yellow light will turn ON continuously after you test your UPS
battery’s charge with the “Mute/Test” Switch to indicate that the UPS’s
battery is less than fully charged. If it stays on continuously, contact
Tripp Lite for service. The light will flash after you set the “OFF/ON”
Switch to the “OFF” position to indicate that the UPS will not provide
battery backup during a blackout or brownout.
Whenever your UPS is automatically correcting high or low AC line
voltage, this green light will turn ON and the UPS will gently click. The
more the UPS has to correct voltage, the more the green light will turn
ON and the more the UPS will click. These are both normal, automatic
operations of your UPS, and no action is required on your part.
This red light will turn ON when the UPS’s capacity has been exceeded
while it is operating from battery power (either during a self-test or
during a blackout). Remove overload from battery-supported outlets
immediately.

Other UPS Features
AC Receptacles
The receptacles provide your connected equipment with AC line
power during normal operation and battery power during black-
outs and brownouts. They also protect your equipment against
damaging surges and line noise. Select models, however,
feature “surge-only” receptacle(s) (identified on the back of the
UPS) that provide peripherals with surge protection without
committing precious battery power to support them during
blackouts.
RJ11 Telephone Jacks (Available on select models)
These jacks protect your equipment against telephone line
surges. Connecting your equipment to these jacks is optional.
Your UPS will still work properly without this connection.
DB9 Port (Available on select models)
The DB9 port connects your UPS to any workstation or server.
Use with Tripp Lite software and cabling to automatically save
open files and shut down equipment during a blackout. This port
sends contact-closure signals to indicate line-fail and low-
battery status. Contact Tripp Lite Customer Support for more
information.
Battery Replacement Door
Under normal conditions, the original battery in your UPS will
last several years. Battery replacement should be performed
only by qualified service personnel. Refer to “Battery Warnings” in
the Safety section on page 2.
