► For the operation of the controller, connect RESET-COM to the GND star point
①�
WARNING!
Faulty laying of the supply and signal cables
> Deterioration of the safety function and EMC
► Basically lay all supply and signal cables 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�
Provide the unconnected signal inputs with sealing of the individual cores�
Unconnected cores or core loops are not permitted�
In case of signal failures, operate inputs with shielded cables� Connect the
shields to the shield connection on one side�
WARNING!
Load dump and surge
> Destruction of the device or deterioration of the safety function
► Always connect VBB
0
�
The CAN bus is internally protected against short circuit to VBB and GND�
For CAN cables ≥ 30 m, ensure appropriate protection against surge (e.g.
shielded cables)�
6.5.1 GND connections
► Connect the GND

and GND
SYS
connections individually to the common GND
star point�
► Connect the GND connections of the sensors of the high-side digital inputs
(CSO) and the actuators (loads) to the common GND star point�
