The location of the holes for wall mounting of the SCALANCE W788-xPRO/RR / W74x-
1PRO/RR is shown in the following diagram:
Premature aging of the device and cables due to UV radiation
For applications outdoors, the use of the hardware SCALANCE W786 is advisable due to
its greater suitability.
Protect the SCALANCE W788-xPRO/RR or W74x-1PRO/RR from direct sunlight by
providing suitable shade. This avoids unwanted heating of the device and prevents
premature aging of the device and cabling. When operating the SCALANCE W outdoors, it
must be mounted so that it is protected from UV.
UV radiation can discolor the front panel of the SCALANCE W788-xPRO/RR or W74x-
1PRO/RR. Discoloring of the front panel does not impair the mechanical stability of the
device. The device must also not be subjected to long periods of rain (provide cover to
protect from rain). The cover should be made of a synthetic material since metal impairs the
radiation of radio waves.
Note
The minimum distance to fluorescent lamps should be 0.5 m. When installed in a cabinet, we
recommend that you do not install relays on the same or on directly neighboring mounting
rails.
