“REPLACE BATT” LED: This red light will be lit and the UPS alarm
will sound three beeps* if your UPS’s microprocessor detects a
battery fault or if your UPS fails the automatic self-test (after you turn
your UPS ON) and the UPS battery is less than fully charged. Let the
UPS charge for 12 hours, then perform a second self test (see p.5 for
details). If the light continues to stay on, contact Tripp Lite for service.
*After the initial alarm, the UPS will beep once every hour until the problem is corrected.
AC Receptacles: These receptacles provide your con-
nected equipment with pure sine-wave AC output from the
AC line during normal operation and from battery power
during blackouts and severe brownouts. Power provided
at these outlets is filtered to protect connected equipment
against damaging surges and line noise. Each UPS
model includes a select number of receptacles arranged
into two separate load banks (clearly indicated on the
rear panel of the UPS system). Using PowerAlert
Software and RS-232 communications, power at either of
these load banks may be turned ON and OFF remotely
without affecting the power output at any other recepta-
cles. See PowerAlert Software instructions for details.
Input Circuit Breaker Switch: This resettable breaker prevents high
input current from damaging the UPS or the attached load. If this
breaker trips, make sure your UPS is connected to AC power of the
proper voltage before resetting the circuit breaker by pushing the
breaker switch in.
Fan: The fan cools the UPS’s internal components. It is always on
when line power is present.
External Battery Pack Connector: Use to connect optional Tripp Lite
Battery Packs for additional runtime. Contact Tripp Lite Customer
Support at (773) 869-1234 for the appropriate Tripp Lite battery pack
to connect. Refer to instructions available with the Battery Pack for
complete connection information and safety warnings.

“BYPASS” LED: This yellow light will be lit when the UPS’s
DC/AC inverter is deactivated and the UPS is in the “Bypass” mode.
During normal operation this LED will light briefly when the unit is
plugged in, but if an internal fault or overload occurs this light will
illuminate constantly to show that connected equipment will receive
filtered AC utility power, but will not receive battery power during a
blackout. In this case, contact Tripp Lite for service.
“FAULT” LED: This red light will flash when your UPS detects an
internal fault (overheating, overvoltages, etc.) or when it detects a
wiring fault in your wall outlet (reversed phases, missing ground,
etc.) The UPS will only detect wiring faults when it is plugged into
a utility outlet but not turned ON. If the light persists after restarting
the UPS, contact an electrician to check the AC line. Your UPS will
identify the presence of most (but not all) wiring faults.
“LOAD ACTIVE METER” LED: This green light will illuminate
when your UPS is receiving AC power to indicate that the set of four
dual-function LEDs is displaying the load level of your UPS.
“BATT ACTIVE METER” LED: This green light will be lit when
your UPS is operating from battery power to indicate that the set of
four dual-function LEDs is displaying the battery charge level of your
UPS. Note: the “ON BATT” LED will also be illuminated.
“OVERLOAD” LED: This red light will be lit when your UPS’s capaci-
ty has been exceeded while it is in on-line operation. The UPS alarm will
beep continuously. Immediately remove overload until light and alarm
go off. If you do not immediately remove the overload, the UPS will
transfer from on-line to bypass operation.
“BATT LOW” LED: This yellow light will be lit when your UPS’s
battery charge level is low. The UPS alarm will beep until either the
battery charge is depleted or the batteries are adequately recharged.
“ON BATT” LED: This green light will be lit when AC line voltage
is not present and your UPS is providing your equipment with battery
power. The UPS will also beep every two seconds, unless silenced by
the “ON/TEST” Switch. When this light is illuminated, you can monitor
the battery charge level of your UPS on the “BATT ACTIVE
METER” LEDs.
