It is recommended to use only commercially available PROFIBUS connectors for
connecting to the bus. Use connectors from ERNI and Siemens. If the C-BOX is
installed at the beginning or end of the PROFIBUS cable segment, it is
recommended to use PROFIBUS connectors, which contain an integrated
terminating resistor.
