Shielding
• Take care of the following items for shielding:
– All shields have to be connected on both ends and all the way around.
– 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 output channels and all counter and frequency output channels must
be wired using shielded cables.
