Shielding
• Take care of the following items for shielding:
– All shields have to be connected on both ends and all the way around.
D-Sub connector shielding:
– If extension lines are used for the sensors, it is not permitted to con-
nect the shielding with a connector pin. The shieldings should be con-
nected 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 conductive cases.
– The ground wire minimizes the effects of ground loops.
– All unused connectors should be protected with a dummy plug (con-
ductive cover or the connectors or connector housings which are part
of the scope of supply).
Information
All analog input and output channels and all counter and frequency output chan-
nels must be wired using shielded cables.
