3.5 Installing the field bus
When installing the connection, make sure that the control and signal cables
(0–10 V, 4–20 mA, 24 V DC, etc.), as well as the communication system’s
(PROFINET) connection cables, are not routed directly parallel to mains con-
nection or motor connection cables conveying power.
With parallel cable routing, the clearances between control, signal and field
bus cables
②
and energy-carrying mains and motor cables
①
must be
greater than 30 cm.
Cables should always intersect at right angles.
Figure 13:

②
and mains/motor cables
①
If the system requires a parallel routing in cable ducts, a partition must be
installed between the
fi
eldbus cable
②
and the mains and motor cable
①
,
in order to prevent electromagnetic interference on the fieldbus.

￫
Never lay the cable of a field bus system directly parallel to the
energy carrying cables.
￫
In all cases only use approved PROFINET cables.
