4.2Connecting a 24 V power supply
>Switch off the main power supply including the external 24 V power source and make sure these cannot be accidentally switched back on again.
>Connect the external 24 V voltage supply (150 mA) to X11.1 (+) and X11.2
>Ground the X11.3 terminal by as short a route as possible (for EMC reasons).
REMARK
24 V DC power source
Several bus modules can be operated with one power supply.
>In cases of SELV (safety extra low voltages) do not ground the 24 V power source.
4.3Connecting the power controller to X1-X8
>Switch off the main power supply including the external 24 V power source and make sure these cannot be accidentally switched back on again.
>Connect the interfaces X1 to X8 of the bus module to the system interfaces of the power controller (shielded

4.4 Connecting the Ethernet bus module to the master
The Ethernet bus module has two Ethernet ports which are equipped with a switch functionality which allows a line topology to be constructed.
A standard patch cable is required for connecting with a switch. For a direct connection (line topology) a
