Solution
Let the UPS system charge for at least 12 hours
and perform a self test using the "ON/Test Switch"
as described in the Basic Operation section. 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.
