Safety notes relating to installation
CAUTION
Danger of injury by falling objects
If the SCALANCE W7x8 is subjected to strong vibration (> 10 g), mounting on a 35 mm DIN
rail does not provide adequate support. Under such conditions, the device can come out of
the mounting and may cause injury.
In this case, install the device on an S7-300 standard rail or on a wall.
CAUTION
Minimum distance to antennas
Fit the device so that there is a minimum clearance of 20 cm between antennas and
persons.
WARNING
If a device is operated in an ambient temperature of more than 40 °C, the temperature of
the device housing may be higher than 70 °C. The device must therefore be installed so
that it is only accessible to service personnel or users that are aware of the reason for
restricted access and the required safety measures at an ambient temperature higher than
40 °C.

Laying the cables
Connecting up cables prior to mounting
Before you screw a SCALANCE W786 to a wall or to the optional mounting plate, the cables
for the power supply, for Ethernet, and, when necessary, for the external antennas must be
connected up first. The available options are as follows:
Figure 5-2 Side view of a SCALANCE W786 with cables entering from different directions
●The cables are inserted from above (position
A
in the previous schematic). The housing
of the SCALANCE W786 has an opening at the top for this purpose.
●The cables are inserted from below (position
B
in the previous schematic). There is also
an opening at the bottom for this purpose.
●Cables inserted through a wall behind the SCALANCE W786 (position
C
in the previous
schematic). In this case, you will need to mount the SCALANCE W786 so that the
opening in the wall is located above the lower edge of the device.
