4.4 Wiring an RF180C to a controller with RJ45 connector
A connection can be easily implemented from an RJ-45 connector to an M12 connector.
Self-assembly of an RJ-45-to-M12 cable
● You will need a preassembled PROFINET cable with M12 connectors at both ends twice
● You will need the following individual parts: RJ-45 and M12 plug-in cables and

This connection variant must always be used when the controller electronics is installed in a
cabinet. The following figure shows the connection layout.

Connecting the RF180C to functional ground (PE)

Features
You have to connect the RF180C to the functional ground (PE). For this purpose, a
grounding screw for one grounding cable is provided on the communication module.
If a grounded metal mounting surface is used, the bottom mounting screw of the RF180C
module already establishes a reliable grounding connection. This eliminates the need for a
separate grounding cable.
The connection to functional ground (PE) is also required to deflect the interference currents
and for electromagnetic compatibility.
28
the required length. You will also need two RJ-45 connectors for self-assembly. Cut the
M12 cable in the center and connect one RJ-45 connector to each free cable end. This
will result in two RJ-45-to-M12 cables.
PROFINET standard cable (unassembled). The parts can be found in the ordering data.
You can make up a cable to your own length requirements using these parts.
