With regard to the CAN bus, there are two ways of attaching the shield:
1. Attaching the shield with the help of shield clamps:
The shield of the bus cable can be attached to the converter
housing with the help of shield clamps (Compact units) or shield
clamps and cable ties (chassis units). How to use the shield clamps
is shown in Fig. 8.4-8 and Fig. 8.4-9. In this case, the shield must
not be exposed in the bus connector at the CBC but at the converter
housing (see Fig. 8.4-10).
2. Attaching the shield in the connector housing:
The shield of the bus cable can be connected to the shield of the
connector housing and is then connected to the CBC board via the
connector and to ground as well (see Fig. 8.4-7).
