Cable Shield Connections
If possible, the cable should be grounded at the source device. If that is not
possible, the cable shield must be grounded at the source device. If that is not
possible, the cable shield must be grounded at the I/O module. This can be
done using an Auxiliary I/O Terminal (IC200TBM001, 002, or 005).
If the module is installed on a Terminal-style I/O Carrier (IC200CHS001, 002, or
005), shield connections can be made on an Auxiliary I/O Terminal that is
attached to the I/O carrier.
If the module is installed on a Compact Terminal-style I/O Carrier
(IC200CHS022, 025), shield connections can be made on an Auxiliary I/O
Terminal that is mounted near the I/O carrier. Be sure to ground the Auxiliary
I/O Terminal Strip if you plan to use it for this purpose.
If the module is installed on a Connector-style I/O Carrier (IC200CHS003), the
cable shield can be connected directly to an Interposing Terminal
(IC200CHS011, 012, 015). Be sure to ground the Interposing Terminal. It is
recommended to use a shielded interposing cable as well between the
Interposing Terminal and the Connector Base. A custom shielded cable can be
made using the Connector kit (IC200ACC304). In addition, a custom shield
braid can be wrapped around standard Interposing Cables (IC200CBL105, 110,
120, 230). If this approach is used be sure to ground the braid.
