Mounting With Mounting Plate; Mounting The Mounting Plate To The Wall - Siemens SIMATIC NET SCALANCE W786 Series Operating Instructions Manual

Follow the steps below to screw a SCALANCE W786 to a wall:
1. Lead the cables into the housing of the SCALANCE W786 (position A in the figure above).
Note the information in the section "Connecting up cables".
2. Secure the SCALANCE W786 to the wall with three screws (position B in the figure above).
The screws are not supplied with the device. The type and length of the screws depend on the
type of wall.
Type of screw:
– for wooden walls: wood screw 4 x 30 mm
– for concrete walls: 4 x 50 mm with 5 mm concrete plug
– for metal walls: M4 x 25 mm with machine thread in the wall
Option: Threaded holes on rear of housing
When a wall is extremely thin, it is often not possible to use wall plugs for the screws. To allow
wall mounting even in this situation, there are four M4 threaded holes on the rear of the
SCALANCE W786. The drilling template is a square with sides 100 mm long. The device can
therefore be mounted on a wall with bolts through the wall.
Calculate the length of the required M4 screws as follows:
Screw length = wall thickness + 7 mm

Note
Installation location
The following should 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 fitting the mounting plate to a wall is shown in the following figure:
