Additional Installation Tips

When experiencing communication problems in noisy environments or when
operating close to temperature limits, the following recommendations are to be
noticed.
6.1

Grounding the operator panel

The VESA mounting of the operator panel does not provide a secure grounding
connection between the panel and the device cabinet, see drawing above.
Connect a wire or grounding braid, that is sized correctly according to local
electrical codes, between the chassis of the operator panel and the closest
grounding point.
Note:
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 does 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.
