Connecting DeviceNet (X30D)
The connection to the DeviceNet fieldbus system is in preparation.
Pin assignment
The assignment of connecting terminals is described in the DeviceNet specification
(Volume I, Appendix A).
The DHF21B/41B option is opto-decoupled on the driver side in accordance with the
DeviceNet specification (Volume I, Chapter 9). This means the CAN bus driver must be
powered with 24 V voltage via the bus cable. The cable to be used is also described in
the DeviceNet specification (Volume I, Appendix B). The connection must be made
according to the color code specified in the following table.

Check and correct the PROFIBUS
station address set on the DIP
switches.
2.
Switch on all inverters again. The
