operational problems. Note: If the “FAULT” LED illuminates, determine the specific
fault condition by activating the error code LEDs. To activate the error code LEDs,
press the “ON/TEST” button until the UPS system beeps, then release the button. The
error code LEDs will illuminate for 5 seconds.
Illuminated LEDs Condition and Solution
On: REPLACE BATT
Error Code LEDs: Not Applicable
Replace Battery: Allow the UPS system to charge for at least
12 hours and perform a UPS system self-test as described
in Section 3.1: Front Panel Switches. If the LED remains on,
contact Tripp Lite for service.
Flashing: LINE
Error Code LEDs: Not Applicable
Input Abnormal: Utility power voltage or frequency is too high
or too low for the UPS system to operate in BYPASS mode.
If an inverter failure occurs, the UPS system will not pass
through utility power to the outlets and any connected equip-
ment will turn off.
On: FAULT
Error Code LEDs: 50% 100%
Battery Weak: Allow the UPS system to charge for 12 hours. If
the LED remains on, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: 25% 75%
Inverter Over-Current: Reduce the load supported by the
UPS system by unplugging some equipment. Restart the UPS
system. If the problem persists, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: 25% 75% 100%
Internal Temperature Too High: Confirm that adequate space
exists for air to circulate near the UPS system’s vents. Confirm
that the UPS system’s fan is working properly. Confirm that the
ambient temperature does not exceed recommended levels.
Restart the UPS system.
On: FAULT
Error Code LEDs: 25% 50%
Inverter Overload: Reduce the load supported by the UPS
system by unplugging some equipment.
On: FAULT
Error Code LEDs: 25% 50% 100%
Charger Out of Order: Restart the UPS system. If the problem
persists, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: 25% 50% 75%
Fan Out of Order: Restart the UPS system. If the problem
persists, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: 25% 50% 75% 100%
Bypass Phase Can’t Lock: Restart the UPS system. If the
problem persists, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: BATT 25%
Utility Voltage Low and Battery Disconnected at
Initialization: Shut down the UPS system. Check the internal
battery connections. Correct the AC input voltage. Restart
the UPS system. If the problem persists, contact Tripp Lite for
service.
On: FAULT
Error Code LEDs: BATT 25% 100%
Battery Disconnected at Initialization and Utility Voltage
or Frequency Too High or Too Low in On-Line Mode: Shut
down the UPS system. Check the internal battery connections.
Correct the AC input voltage. Restart the UPS system. If the
problem persists, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: BATT 25% 75%
Input Over-Current: Reduce the load supported by the UPS
system by unplugging some equipment. Restart the UPS
system. If the problem persists, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: BATT 25% 50%
Bypass Overload: Reduce the load supported by the UPS
system by unplugging some equipment. Either wait for the
UPS system to recognize the load reduction or restart the UPS
system. If the problem persists, contact Tripp Lite for service.
On: FAULT
Error Code LEDs: BATT 25% 50% 100%
Battery Voltage Too High: Restart the UPS system. If the
problem persists, contact Tripp Lite for service.
Note: All other error codes indicate internal fault conditions. Restart the UPS system. If the problem
persists, contact Tripp Lite for service.
