Screwing the cover plate for the cable feedthrough to the mounting plate

Protection of the cable feedthrough against strong water jets
The cabling of a SCALANCE W786 is led out of the rear of the device. The housing seal is
effective only when it is not subjected to water jets. If the device is mounted on a wall, this is
the case and no further measures are necessary. When mounted in any other way, except
for mounting on an S7-300 standard rail, an additional cover plate must be screwed to the
mounting plate.
Danger from line voltage
If the cable feedthrough is subjected to strong water jets, water can penetrate the device
and create a live connection to the line voltage. There is then a risk of electric shock.
Make sure that you use the cover plate for the cable feedthrough if you do not mount the
SCALANCE W786 on a wall.
