Ground material
The following materials are recommended for grounding:
Ground wires: flex YF 4 mm² gn/ye, AVL number EX0301.
Ground braid: tin-plated Cu 10 mm² (rolled), AVL number EX0441 Ground
Strap.

Shielding
All shields have to be connected on both ends and all the way around (see
Fig. 12).
If extension lines are used for the sensors, it is not permitted to connect the
shielding with a connector pin. The shieldings should be connected through the
connector case.
If other devices are connected using voltage or current interfaces, then the
shielding on the side of these devices should be connected with low inductance
to their cases.
The ground wire minimizes the effects of ground loops.
All unused connectors should be protected with a conductive connector case.
Information
All sensors have to be shielded.
