Troubleshooting
WARNING!
An electric shock can be fatal. Before opening up the machine
-
Move the mains switch to the “O” position
-
Unplug machine from the mains
-
Put up 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 electri-
cally charged components (e.g. capacitors) have been discharged

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 that do not provide a reliable PE conductor connection.
