Solution
Let the UPS system charge for at least 12 hours
and perform a self test using the "ON/Test
Switch" as described on page 6. 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,

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.
