open.
Battery or site wiring
problem has occurred.
UPS is in sleep mode.
Heat damage or recent
air conditioning outage
has occurred.
Batteries need charging
or service.
Alarm is not appropriately
set.
Cause depends on the
specific LED.
Possible Solution
Connect the line cord.
Push the circuit breaker button or replace
the fuse. If this occurs repeatedly,
contact an authorized service provider.
Check the UPS LEDs. Refer to the UPS
documentation.
Disable sleep mode for proper operation.
The UPS has a sleep mode that can be
turned off through the configuration mode
on the front panel. Sleep mode initiates if
the power is removed and no load shows
on the UPS.
Change the battery. The optimal
operating temperature for UPS batteries
is 25ºC (or 77ºF). For approximately
every 8°C to 10°C (16°F to 18°F)
average increase in ambient temperature
above the optimal temperature, battery
life is reduced by 50 percent.
Plug the UPS into an AC grounded outlet
for at least 24 hours to charge the
batteries, and then test batteries.
Replace the batteries if necessary.
Change the amount of time given before
a low battery warning. Refer to the UPS
documentation for instructions.
