Shielding
The screen is to be connected over the entire length of the bus cable, and only galvanically grounded at one
point, in order to avoid ground loops.
The design of the screening, in which HF interference is diverted through R/C elements to the mounting rail
assumes that the rail is appropriately earthed and free from interference. If this is not the case, it is possible
that HF interference will be transmitted from the mounting rail to the screen of the bus cable. In that case the
screen should not be attached to the couplers - it should nevertheless still be fully connected through.
Notes related to checking the CAN wiring can be found in the
