Assembly and Installation Notes
LED L18
(Run PROFIBUS)
LED L18 (Run PROFIBUS) indicates that the PROFIBUS electronics (hardware) is
working properly.
4.8.4 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.

• The PROFIBUS station address set on
the DIP switches exceeds 125. If the
PROFIBUS station address is set to a
value higher than 125, the DHF21B/41B
option will use PROFIBUS station
address 4.
1. Check and correct the PROFIBUS
station address set on the DIP
switches.
2. Switch on all inverters again. The
modified PROFIBUS address will
only take effect after a restart.
