4.4 Connecting the Ethernet communication cable
Always use a shielded cable for the Ethernet data cable.
1. Plug the RJ45 cable connector into the RJ45 device socket until the connector engages
in the socket.
2. Provide sufficient mechanical strain relief for the Ethernet cable.
3. Ground the shield of the cable (see chapter Grounding of the Ethernet communication
cable (Page 34)).
4.4.1

Grounding for Ethernet

When using industrial LAN cables, corresponding strain relief must be provided.
NOTICE
Ethernet cables must be grounded.
The upper limit values will be exceeded if the cable is not grounded.
Compliance with the technical limit values for noise radiation and noise immunity is only
guaranteed if the cable is correctly grounded. The operator of the system is responsible for
ensuring compliance with the statutory limit values (CE mark). Make a shield connection as
described here.
Version
Ground the Ethernet cable. To do this, expose the foil shield of the cable. Connect the
exposed shield to a suitable grounding point on the control cabinet, preferably a shielding
bus.
