5 Mounting 5.2.2.4 Information about shielding the CAN bus In order for the CAN bus to operate faultlessly, you have to connect the shielding using one of the following variants. If you are not able to use any of the variants detailed below, we recommend using fiber-optic cables. Fiber- optic cables decouple the devices and are not sensitive to electromagnetic interference (surge and burst).
5 Mounting ▪ Be aware of sharp edges because they can damage the fiber-optic ca- ble's coating during laying or can place mechanical loads on the coating later on. ▪ Provide a sufficient cable reserve near distributor cabinets. Lay the re- serve such that the fiber-optic cable is neither bent nor twisted when tightened.
