4.2 Securing the housing
Grounding terminal
To operate the SCALANCE W788 safely, the housing must make contact with a chassis
ground cable. Do not use the SCALANCE W788 without a ground cable connected.
The ground cable can be connected to one of the securing screws. To allow this, several of
the screw contact surfaces in the housing do not have a powder coating. You will find these
contact surfaces on the right-hand side of the housing (when looking at the front of the
housing).
Wall mounting or standard rail
Note
Installation location
There are no restrictions regarding the installation location for the device.
Antennas, in particular directional antennas, must be mounted in keeping with their
characteristics (refer to the technical specifications of the antenna --> Radiation pattern
diagrams).
There are two ways of securing the housing:
● Wall mounting
Use the holes in the housing to screw the device to the wall or on a horizontal surface.
● Standard rail mounting
Mount the SCALANCE W788-xPRO/RR or W74x-1PRO/RR on a 90 mm long, vertically
mounted section of standard rail (S7-300). In this case, the standard rail serves as an
adapter between the wall and SCALANCE W788-xPRO/RR or W74x-1PRO/RR. If you
want to mount the SCALANCE W788-xPRO/RR or W74x-1PRO/RR along with a PS791-
1PRO, you will require a 150 mm long standard rail.
Make sure that there is suitable strain relief for the connecting cable.
