2. Mounting

In order to expose the controller to the minimum mechanical stress, it should
preferably be mounted horizontally or vertically on the mounting panel. The
device must be fixed with four screws to DIN 7500 or 7984 (M5 x L).
If possible, the controller should be mounted with the cable entry of the plug
pointing downwards.
As the internal heating of the device electronics is dissipated via the housing,
sufficient cooling must be ensured in case of "sandwich mounting" of
controllers.

3. Electrical connection

To ensure the protection of the device against electrical interference, the housing
must be connected to ground (e.g. to the ground of the vehicle).
To protect the whole system (wiring and controller) the individual electric circuits
of each control unit must be protected.

3.1 Interaction between the inputs and outputs within one group of
connections
In safety-related applications the following must be observed as regards the use
of the terminals as input and output:
Within one output group inputs and outputs should not be mixed. One output
group is marked by a common VBB
The background is a possible internal cross-connection of the outputs from the
externally supplied inputs. This may occur unexpectedly if the supply to the
outputs is switched off externally.
Should a mixture still be carried out for reasons of optimising the terminals,
please inform yourself in detail about the situations described in the system
manual and the restrictions resulting from this. Follow these instructions for your
application and keep records of this.
