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. -

In principle the CAN bus must be realized in a line. The nodes are connected to the main • CAN bus line via short cable stubs. This is normally realised by so called T-connectors. esd offers the CAN-T-Connector (Order No.: C.1311.03) If a mixed application of single twisted and double twisted cables cannot be avoided, •... -

CAN bus line via short cable stubs. This is usually realised via so called T-connectors. When using esd's CAN-T-Connector (order no.: C.1311.03) in heavy industrial environment and with four-wire twisted cables, it must be noted that the shield potential of the conductive DSUB housing is not looped through this type of T-connector. -

Page 28: Electrical Grounding
CAN Troubleshooting Guide 7.2 Electrical Grounding The CAN_GND of the CAN network should be connected to the functional earth potential (FE) at only one point. This test indicates whether the CAN_GND is grounded at one or more points. Please note that this test can only be performed with electrically isolated CAN nodes. To test this, please proceed as follows: Disconnect the CAN_GND from the earth potential (FE). -
