Note:

For CE compliance, the communication cable shield must
be connected directly to the chassis ground terminal
located on the communication card cover plate. The
exposed shield wire should be as short as possible.

Field Service Considerations

If the Smart Communications Card requires service,
please contact your nearest Allen-Bradley Sales Office.
To minimize your inconvenience, the initial installation
should be performed in a manner which makes
removal easy.
