3.7 Install field bus
When installing the connection, make sure that the control and signal cables
(0 - 10 V, 4 - 20 mA, 24 VDC, etc.), as well as the field bus system‘s
(PROFINET) connection cables, are not routed directly parallel to mains
connection or motor connection cables conveying power.
With parallel cable routing, the clearances between control, signal and field
bus cables
and energy-carrying mains and motor cables
must be
greater than 30 cm. Cables should always intersect at right angles.
Figure 14:Routing cables for PROFINET
and
mains/motor cables
If the system requires a parallel routing in cable ducts, a partition must be
installed between the field bus cable
and the mains and motor cable
,
in order to prevent electromagnetic interference on the field bus.
