pensed with entirely. After a possible malfunction or error has been remedied, the power
source can be put back into normal operation again without any fuses having to be re-
placed.

If any error message that is not described here appears on the displays, then the fault can
only be fixed by a service technician. Make a note of the error message shown in the dis-
play and of the serial number and configuration of the power source, and contact our After-
Sales Service team with a detailed description of the error.
WARNING! An electric shock can be fatal. Before opening the device:
- Move the mains switch to the "O" position
- Unplug the device from the mains
- Put up an easy-to-understand warning sign to stop anybody inadvertently
switching it back on again
- Using a suitable measuring device, check that electrically charged parts (e.g.
capacitors) have been discharged
CAUTION! Inadequate PE conductor connections can cause serious injury and
damage. The housing screws provide a suitable PE conductor connection for
earthing (grounding) the housing and must NOT be replaced by any other screws
which do not provide a reliable PE conductor connection.
