WARNING! An electric shock can be fatal. Before opening the device
- Turn 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 instrument, check to make sure that electri-
cally 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 that do not provide a reliable PE conductor connection.
