4. Electrical connection
4.1 Wiring
Wiring see technical data.
Only connect the connector pins as shown in the pin layout.
Unspecified connector pins remain unconnected..
Connect all supply cables and GND terminals.
4.2 Ground connection
To ensure the protection of the device against electrical interference and the safe func-
tion of the device, the housing must be connected to the ground of the vehicle.
1: Drill hole for ground connection
Establish a connection between the device and the ground of the vehicle using
M5 screws. Screws to be used ( ¨ 4.1 Fastening)
4.3 Fuses
The individual electric circuits must be protected in order to protect the whole
system.
4.4 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
X
potential.
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, 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.
