Chronic mild brownouts that cause the UPS to switch to battery
power frequently could leave your batteries low on charge. The
adjustable voltage potentiometer allows you to prevent excessive
battery drain by lowering the voltage point at which the UPS
switches to battery. To keep your UPS from switching to battery
during mild brownouts, turn the potentiometer clockwise to lower
the voltage point as much as 18% below the nominal setting of 190
volts (when set fully clockwise).
Note: Your UPS’s optimal setting will depend on the voltage conditions in your area. Adjust the
potentiometer clockwise only if you want to reduce how often your UPS switches to battery. Your UPS will
function properly at any setting. Use caution when adjusting the potentiometer while the UPS is powering
voltage-sensitive loads.
Other UPS Features
AC Receptacles
The receptacles provide your connected equipment with AC line
power during normal operation. They will provide battery power
during blackouts and brownouts only if the “OFF/ON” Switch is
set to the “ON” position. The receptacles also protect your
equipment against damaging surges and line noise.
RJ11 Telephone Jacks
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.
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 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.

DB9 Serial Port
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. It also receives a shut down signal from the
connected computer to conserve the UPS battery charge. Contact
Tripp Lite Customer Support for more information.
