SMT-BD1/t
If there is a potential reference, i.e. a main chassis or cabinet with a low impedance between its various elements,
it should be used to connect ALL reference to it and also being grounded itself.

The cable can be soldered on the shield
because the connector box is metallic.
This solution does not exactly meet
the EMC requirements but
it is acceptable.

NOTE
When the 360° shield connection is made by means of a collar, it is not necessary to connect a cable on the
appropriate pin of the SUB-D connector.
