Connecting the bus coupler as a final station

1. If you do not use pre-assembled wiring, connect the plugs
according to Table 5 on page 63.
2. Connect the incoming bus connection to the X71 input (1).
3. Cover the X72 (BUS OUT) socket with a bus coupler termination plug
(see "Spare parts and accessories" on page 79).
4. Ensure that the plug housing is securely fitted to the bus coupler
housing.
A potential equalization line of at least 10 mm
the devices to avoid compensating currents from flowing over the
shield of the bus coupler.

Connecting power supply

The POWER socket (X10) is used for power supply to the internal
electronics of the bus coupler and for two different external power
supply sources (24 V) to the valves.
The pin assignment corresponds to the information in Table 6. For pre-
assembled cables, see „Spare parts and accessories" on page 79.".
