If the light continues to stay on, contact Tripp Lite for service. Prepare for imminent UPS shutdown. Reduce the load the UPS supports. Remove the cause of the short circuit from the UPS output. Check the utility line for wiring problems such as reversed line and neutral or a missing ground. Restart the UPS. If the problem persists, contact Tripp Lite for repairs. Restart the UPS. If the problem persists, contact Tripp Lite for repairs. Restart the UPS. If the problem persists, contact Tripp Lite for repairs. Restart the UPS. If the problem persists, contact Tripp Lite for repairs. Restart the UPS. If the problem persists, contact Tripp Lite for repairs. Check the UPS to be sure that there is adequate space for air to circulate near the vents and that the fan is working properly. Restart the UPS. This indicates that utility power is too high or low for the UPS to operate in BYPASS mode, so if an inverter failure occurs, the UPS will deliver no output. Restart the UPS. If the problem persists, contact Tripp Lite for repairs. 10 201102091 93-3092.indb 10 3/29/2011 5:36:47 PM

Troubleshooting
The UPS’s control panel lights will turn on in the sequences below to signal that the UPS is having
operational difficulties.
Lights (On/Flashing) and Condition
Solution
On: REPLACE BATT
Condition: Replace Battery
Let the UPS system charge for at least 12 hours
and perform a self test using the "ON/Test
Switch". If the light continues to stay on, contact
Tripp Lite for service.
On: BATT LOW, ON BATT
Condition: Battery Low
Prepare for imminent UPS shutdown.
On: BYPASS, LINE, LOAD, OVERLOAD
Condition: On Bypass due to Overload
Reduce the load the UPS supports.
Flashing: OVERLOAD
Condition: Short Circuit
Remove the cause of the short circuit from the
UPS output.
On: FAULT
Condition: Wiring Fault
Check the utility line for wiring problems such as
reversed line and neutral or a missing ground.
On: FAULT, 100%
Condition: Battery Voltage too High
Restart the UPS. If the problem persists, contact
Tripp Lite for repairs.
On: FAULT, BYPASS, LINE, 50%
Condition: On Bypass due to High
Output Voltage
Restart the UPS. If the problem persists,
contact
Tripp Lite for repairs.
On: FAULT, BYPASS, LINE
Flashing: 50%
Condition: On Bypass due to Low
Output Voltage
Restart the UPS. If the problem persists, contact
Tripp Lite for repairs.
On: FAULT, BYPASS, LINE, 25%
Condition: On Bypass due to High
Bus Voltage
Restart the UPS. If the problem persists,
contact
Tripp Lite for repairs.
On: FAULT, BYPASS, LINE
Flashing: 25%
Condition: On Bypass due to Low
Bus Voltage
Restart the UPS. If the problem persists,
contact
Tripp Lite for repairs.
On: BYPASS, LINE
Flashing: FAULT
Condition: On Bypass due to High
Internal Temperature
Check the UPS to be sure that there is adequate
space for air to circulate near
the vents and that
the fan is working properly. Restart the UPS.
Flashing: LINE
Condition: Input Abnormal
This indicates that utility power is too high
or low
for the UPS to operate in BYPASS mode, so if an
inverter failure occurs, the UPS will deliver no
output.
On: FAULT, 50%
Flashing: LINE
Condition: No Output due to High Output
Voltage and Abnormal Input
Restart the UPS. If the problem persists, contact
Tripp Lite for repairs.
