Connecting the bus coupler

1. Set up the correct pin assignment (see tab. 6 on page 53) on the plug connections
if you do not use pre-assembled cables.
2. Connect the incoming bus connection to X72 (1) and connect the module with
a hub or switch if further participants are to be connected.
3. Provide the X71 plug (2) with a cover cap.
4. Connect the shield on both sides of the bus cable directly to the plug housing
(EMC housing) if self-assembled cables and plugs with metal housing are used.
This protects data lines from terminal interference. Ensure that the plug housing
is securely fitted to the bus coupler housing.
6.3.3

Connecting the bus coupler logic and load supply

Power is supplied to the valves and the bus coupler via the X10 (POWER) plug.
When connecting the logic and load supply of the bus coupler, ensure pin assignment
according to tab. 7.
