Please have the following information at hand before calling the After-Sales Service Department:
1. Model number, serial number
2. Date on which the problem occurred
3. LCD/LED display information, Buzzer alarm status
4. Mains power condition, load type and capacity, environment temperature, ventilation condition
5. Information on external battery pack (battery capacity, quantity)
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 a 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
