Mounting

SCALANCE W788-xPRO / W74x-1PRO/RR

20 A5E02280448-02, Release 11/2008

CAUTION

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.
