If shielded cables have to be interrupted, the shield must be continued via the corresponding
connector housing. Only suitable connectors may be used for this purpose.
Figure 4-15
If intermediate connectors, which do not have a suitable shield connection, are used, the
shield must be continued by fixing cable clamps at the point of interruption. This ensures a
large-area, HF-conducting contact.
