Safety
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. capaci-
tors) 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.
