4.2.7 Cabling of the Fieldbus

4.2.7.1 Shielding
To achieve a high system resistance to interfering electro-magnetic radiation,
always use a screened data line.

Attention
Only install one central grounding point for the entire CAN bus line. If possi-
ble, establish the connection directly at the bus line using low impedance
screening systems.
The data line should be routed separately from all high current carrying ca-
bles.
Note
WAGO offers the screen connection system, series 790, for an optimum con-
nection between the fieldbus cable screen and the function earth.
As an option, the cable screen can be routed to the ´Shield´ plug pin. By
means of an RC combination, the contact is connected to the function earth
and as such with the carrier rail.
