3. 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
module must be fixed with four screws to DIN 7500 or DIN 7984 (M5 x L).
If possible, the controller should be mounted in such a way that the cable entry
of the plug points downwards.
As the self-heating of the electronics of the unit is dissipated via the housing, suf-
ficient cooling must be ensured in case of "sandwich-mounting" of controllers.

4. Electrical connection

To guarantee the electrical interference protection of the controller, the
housing must be connected to GND (e.g. to the ground of the vehicle).
To protect the whole system (wiring and controller) the individual electric circuits
must be protected.

4.1 Interaction between the inputs and outputs within one group of
connections
In the applications the following must be observed as regards the use of the ter-
minals 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 out-
puts is switched off externally.
Should a mixture still be carried out for reasons of optimising the terminals, plea-
se inform yourself in detail about the situations described in the system manual
and the restrictions resulting from this. Follow these instructions for your applica-
tion and keep records of this.
