Securing the conductor lines to the grounding plate
1
Ground conductor
The connection to ground potential must be as short as possible and sufficiently strong (≥4 mm²) over the
intended spade terminal (Faston 6.3 mm).
2
Shielded lines
A central ground connection is available to effectively deflect interference. All cable shields must be con-
nected to ground with good conductivity using a cable tie on the grounding plate or some other method.
3
Unshielded lines
All unshielded lines must be relieved of tension by using a cable tie to tie them to the grounding plate.

Important!
The ground connection of the device must be low impedance and connected to ground (e.g. grounding
rail in the control cabinet) using a short path.
