In order to assure both the protection class and the required
strain relief, the cable and plug assembly must be done
professionally and in accordance with the assembly instructions.

housing (EMC housing). This protects data lines from terminal
interference. When using a cable with a filler cord, this can be
additionally connected to pin 5 on the bus plug (X71, X72).
