1. The operator panel’s mounting clamps do not provide a secure grounding connection between the panel and the device cabinet.
2. Connect a 2.5 mm2 wire between the operator panel’s quick-connect plinth and the panel chassis.
3. Connect a 6 or 4 mm2 wire or grounding braid between the panel’s chassis and the closest grounding point on the door.
4. Connect a strong but short grounding braid between the door and the device cabinet.
5. Twist the cables onto the 24 V DC feed.
6. A ferrite core suppresses disturbances to the 24 V feed.
2 turns around the ferrite core provide 4 times the suppression of 1 turn.
3 turns around the ferrite core provide 9 times the suppression of 1 turn.

The grounding wires should be short and the conductor should have a large area.A long, thin grounding wire has a very high impedance (resistance) at high frequencies and will not guide disturbances to the ground.Multi-wire conductors are better than single wire conductors with the same area.A braided conductor wire with the same area is even better.The best is a short, thick grounding braid.With longer distances, there is a risk that the ground potential may be different. In that case, the shield should only be connected at one end. A good alternative is to connect the other end of the shield to the ground via a 0.1 uF/250 V plastic capacitor. Both ends are then connected to the ground in terms of HF, but only connected to the ground at one end in terms of LF, thus avoiding the 50 Hz
grounding loops.
