Using shielded cables
When using a shielded cable for the bidirectional inputs/outputs, the following options are
available for the shield connection:
1. Attach the cable shield to a grounded shielding bus immediately after the cable entry point
in the cabinet (strip the insulation o󹪜 the cable for this purpose).
2. Continue routing the shielded cable as far as the module but do not make a connection to the
shield there.
Using a shield connection
1. Remove the 󹪝xing bracket of the shield connection.
2. Insert the cable and fasten the 󹪝xing bracket.
