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.

Removing / fitting the housing cover
When does the housing cover need to be removed?
You can only perform the following activities when the cover is removed.
●You want to screw the SCALANCE W786 to a wall or onto the optional mounting plate.
●You want to connect cables to the SCALANCE W786 for the power supply, for Ethernet
or for external antennas.
●You want to use the reset button.

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.

Grounding terminal
WARNING
To operate the SCALANCE W786 safely, the chassis ground connector must have a
suitable cable connected. Do not use the SCALANCE W786 without a ground cable
connected.
The chassis ground connector is located on the rear of the device (M4 thread). Connect the
ground cable before you mount the SCALANCE W786 on a wall or on the optional mounting
plate. Once the SCALANCE W786 is mounted, the connector is no longer accessible.
Place the supplied toothed washer directly on the rear of the device before screwing on the
ground cable. Only then can you be sure that there is ideal contact with the screwed-on
cable.

Note
Installation location
The following shoul
d be noted with regard to the installation location:
•
Devices with an internal antenna must be aligned according to the characteristics of the
internal antenna (refer to the technical specifications of the antenna --> Radiation pattern
diagrams). Since the internal antennas are integrated in the housing, the location and
alignment of the housing decides the radiation direction of the antennas.
•
There are no restrictions relating to devices without internal antennas.
The location of the holes for mounting the SCALANCE W786 on a wall is shown in the
following figure:
