Earthing system
The following items have to be observed to guarantee a safe dissipation
of electronic interference:
•
Appliance and switch board have to be connected to the nearest
possible central earthing point.
•
make sure of a possibly low inductive connection between appliance
and switch board.
•
All data cables connected to the appliance have to be the screened
type.
•
The screens have to be earthed on both sides. There has to exist a
low ohm connection between the connected systems. High equalising
currents through the cable screen due to voltage fluctuations are to
be avoided.
•
The earthing connection is to be carried out with min. 4 mm² cross
section.
