Possible cause
UPS was manually switched to
bypass and will remain in bypass
until manually transferred out of
bypass
Indicates that the temperature of
heat sink is too high indicating an
over temperature of the UPS.
Indicates that the ambient
temperature is higher than the
operation temperature on
specification
Indicates that the fan is not working
properly.
UPS has an unexpected bypass
current on battery-mode
Indicates that the UPS could not
read the Eeprom successfully
Parallel system: power from one UPS
flows from the parallel output into the
other UPS in the system (negative
power)
Parallel system: Parallel cable
disconnected
UPS1 batteries connected, UPS2
batteries disconnected
Parallel system: UPS1 line ok, UPS2
line lost
Remedy
Check the maintain bypass switch
status
Transfer the UPS to Bypass-mode. If
the condition persists, shut down the
UPS. Clear vents and remove any
heat sources. Allow the UPS to cool.
Ensure the airflow around the UPS is
not obstructed. Restart the UPS.
Change the positioning of the UPS or
use an adequate air conditioning
system.
Check fans of UPS
Transfer to maintenance bypass and
call service.
Contact your service representative
If the parallel system is in redundant-
mode, only the UPS with the failure
will transfer to fault-mode without
output. Other UPS will still support
the load.
If the parallel system is not
redundant and the load cannot be
supported by the other UPS, all units
in the parallel system will transfer to
fault-mode.
Connect the parallel cable
Check battery connections
Check the input line
