Shielding
The shielding is an important component of the CDI cable. The shielding is used
to shield the data wires in the cable against electrical interferences from the en-
vironment. The shielding has to be connected to the potential equalization of the
devices to shield the data wires. In most cases, a connection via the RJ45 con-
nectors is sufficient.
Remove any collection of dirt from the shield surfaces of the RJ45 plugs before
plugging them in.

Additional shielding connection in case of strong electrical interferences and
long cables
In case of strong electrical interferences and long cable lengths, it can be re-
quired to additionally connect the shielding to the earthing potential.
Observe the following for an additional shielding connection:
●
Mount suitable EMC shielding clamp close to the control cabinet PC, the re-
mote operator display or the Y-repeater
●
Ensure that the CDI cable is not crimped when connecting the shielding to
the equipotential bonding
●
Avoid mechanical stress (tensile, compressive) on the plug
●
Use an EMC shielding clamp suitable for the cable diameter. Crimping the ca-
ble impairs the electrical properties of the CDI cable
To mount the shielding connection, proceed as follows:
1. Only remove the CDI cable jacket on the length required for the connec-
tion.
