Grounding the valve unit and connecting the
shield
The conductive housing (and also pin 1) of the data input plug
(X7C) are connected via the grounding plate and the mounting
screw to the ground.
Risk of electrical faults
If the bus coupler has an insufficient ground connection and
strong interference occurs, this could lead to ground return
on the shield, which impedes the transfer.
O
To ensure proper grounding the grounding plate (marked
with the symbol shown in the left margin) must be
connected to the main ground
