The CL03 series bus coupler for PROFINET has a 100 Mbit full
duplex 2-port switch, so that several PROFINET devices can be
connected in series. As a result, the controller can be connected
to either fieldbus connection X71 or X72. Both fieldbus
connections are identical.

cables!
The bus coupler may be damaged.
O
Only use shielded and tested cables.
Faulty wiring!
Faulty wiring can lead to malfunctions as well as damage to
the network.
O
Unless otherwise stipulated, comply with the PROFINET
specifications.
O
Only a cable that meets the fieldbus specifications as well
as the connection speed and length requirements should
be used.
O
In order to assure both the protection class and the
required strain relief, the cable and plug assembly must
be done professionally and in accordance with the
assembly instructions.
O
Never connect the two fieldbus connections X71 and X72
to the same switch/hub.
