►
Basically all supply and signal cables must be laid separately�
►
Connect supply and ground cables to the controller and the sensors/actuators
via the respective common star point�
If a prewired connection cable is used, remove the cores with unused signal
inputs and outputs�
Unused cores, in particular core loops, lead to interference coupling that
can influence the connected controller�
In case of signal failures, operate inputs with shielded cables� Connect the
shields to the shield connection on one side�
VBB
0
must be connected in order to protect the controller against load dump
WARNING
If VBB
0
is not connected, this can affect the safety of operators and
machinery�

connectors individually to the common GND
star point�
►
Connect the shield connection of the housing to the ground / body of the
vehicle in the shortest possible way�
WARNING
Do not connect the GND

and GND
OVA
connectors to the common
GND star point, but to the GND of the signal source or of the connected device�
