"OUTPUT LOAD LEVEL" LED: this multicolored LED indicates the
approximate electrical load of equipment connected to the UPS's AC
outlets. It will turn from green (light load) to yellow (medium load) to red
(overload). If the LED is red (either illuminated continuously or flashing),
clear the overload immediately by unplugging some of your equipment
from the outlets until the LED changes from red to yellow (or green) and
the alarm is no longer sounding. CAUTION! Any overload that is not
corrected by the user immediately may cause the UPS to shut down and
cease supplying output power in the event of a blackout or brownout.
"BATTERY CHARGE" LED: when the UPS is operating from utility
power, this LED indicates the approximate charge state of the UPS's
internal batteries: red indicates the batteries are beginning to charge; yellow
indicates the batteries are roughly midway through charging; and green
indicates the batteries are fully charged. When the UPS is operating from
battery power during a blackout or severe brownout, this LED indicates the
approximate amount of energy (ultimately affecting runtime) which the
UPS's batteries will provide: red indicates a low level of energy; yellow
indicates a medium level of energy; and green indicates a high level of
energy. Since the runtime performance of all UPS batteries will gradually
deplete over time, it is recommended that you periodically perform a self-
test (see MUTE/TEST Button description) to determine the energy level of
your UPS batteries BEFORE a blackout or severe brownout occurs. During
a prolonged blackout or severe brownout, you should save files and shut
down your equipment since battery power will eventually be depleted.
When the LED turns red and an alarm sounds continuously, it indicates the
UPS's batteries are nearly out of power and UPS shut down is imminent.
"BATTERY WARNING" LED: this LED lights red and an alarm sounds
intermittently after you initiate a self test (See "MUTE/TEST" Button
description) to indicate 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 continues to light, 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.
