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 (-) (reverse polarity protec- tion).

>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 four-wire cable)

Attention: To control all parameters by ProfiNet we recommend closing the Thyro-A switches S1.3, S1.4, S1.5 (Thyro-Tool Mode).

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 cross-over cable is required.
