6.2.1 General Rules NOTICE esd grants the EU Conformity of the product if the CAN wiring is carried out with at least single shielded single twisted pair cables that match the requirements of ISO 11898-2. Single shielded double twisted pair cable wiring as described in chapter 6.3 ensures the EU Conformity as well. -
