Troubleshooting
Warning! An electric shock can be fatal. Before opening the machine:
- Shift the mains switch into the „O“ position
- Unplug the machine from the mains
- Put op an easy-to-understand warning sign to stop anybody inadvertently
switching it back on again
- Using a suitable measuring instrument, check to make sure that electrically
charged components (e.g. capacitors) have been discharged.
Warning! 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.
