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.
To ensure that the C-BOX functions without errors, the shield of the PROFIBUS
cable must be grounded.
– Ensure that the PROFIBUS connector uses the pin assignments shown in par 2.9.
– Attach the PROFIBUS connector to the PROFIBUS interface socket on the
C-BOX 3X0 and secure the connector with the retaining screws.
