10Troubleshooting and Fault Rectification
If error messages are displayed, please refer to the following table in order to localise the fault that has occurred and to find information about what measures to take to rectify the fault. If you cannot resolve the problem(s), please contact the Service Center (see page 5 "Hotline").
1.Check whether the UPS connection, and specifically the mains connection, has been made correctly.
2.Check whether the input voltage has been applied correctly (check for phase(s) connected to the neutral conductor and for the phase sequence, if appropriate).
3.Check the connection of the battery system (polarity and nominal voltage).
4.Make a note of the status of the unit when the fault occurred (LC display) and the error code number that is displayed.
