Troubleshooting
General The digital power sources are equipped with an intelligent safety system. This means that
apart from the fuse for the coolant pump, it has been possible to dispense with melting-type
fuses 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 replaced.

WARNING! An electric shock can be fatal. Before opening the device
- Turn the mains switch to the "O" position
- Unplug the machine from the mains
- Prevent it from being switched on again
- Using a suitable measuring instrument, check to make sure that electrically
charged components (e.g. capacitors) have 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.
