The bus must be terminated with a 120 Ω, 1/4 Watt resistor, this must be connected at the ends of the bus.

The central units UCZA/UCZB, the couplers 07 CS 61 and  35 CS 91 have to be connected at an end of the bus. The resistor 120 Ω is integrated.

The other central units and the PC board should be connected everywhere on the bus.

The shield of the bus must be connected to the earth near the master.

When noisy elements are in the area of the cabinet, it is better to connect the bus' shield to the ground via a capacitor 1 nF class Y directly at the access of the cabinet according the following diagram.

The system bus CS 31 is opto-isolated from all units.

The shield is connected to the earth through a capacitor 1 nF class Y, mounted in the plug-in base.

The maximum bus length is 500 metres.

In case of use of a bus amplifier or redondy amplifier refer to their own descriptions.
