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.
