X = not permissible
WARNING
The linking of connections in the plug is not permitted and can affect the safety of
operators and machinery�
► Basically all supply and signal cables must be laid separately�
► Connect supply and ground cables to the controller and to 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�
5.5 Frequency and analogue inputs
► Operate frequency inputs with screened cables, so that useful signals are not
affected by external interference�
► Connect screens to ground on one side�
