be a wall, a mounting plate or the surface of a device or vehicle.
The holes in the PROFIBUS ILM are intended for screws with a thread diameter of maximum 4.5 mm and a
screw head diameter of maximum 8.5 mm.
Figure 11 shows the location of the holes drilled in the ILM.

Select the site for installing the module so that the climatic limit values and mechanical stress values as
described in the technical specifications are adhered to. When installing the module, make sure, in particular,
that no direct sunlight falls on the device otherwise both the temperature range of the device (maximum 60 C)
and the light intensity in the infrared range will be exceeded and cause functional problems. It is advisable to
protect the device with a "sunshade" making sure that it cannot subjected to direct sunlight even when the sun
is extremely low.
Note
Make sure that there is sufficient space to connect the bus and power supply cables. The cables must not
extend into the area of the send and receive window.
