General Notes
General
Cables should be grouped together, for example: signal cables,
data cables, heavy current cables, power supply cables.
Heavy current cables and signal or data cables should always be
routed in separate cable ducts or bundles. Signal and data cables
must always be routed as close as possible to ground potential
surfaces (for example support bars, cabinet sides etc.).
Cable Routing
Correct cable routing prevents or suppresses the reciprocal influ-
encing of parallel routed cables.
Cable Routing Inside and Outside of Cabinets:
To ensure EMC-compatible cable routing, the cables should be
grouped as follows:
Various types of cables within the groups can be routed together in
bundles or in cable ducts.
Group 1:
shielded bus and data cables
shielded analog cables
unshielded cables for DC voltage ≤ 60 V
unshielded cables for AC voltage ≤ 25 V
Group 2:
unshielded cables for DC voltage > 60 V and ≤ 400 V
unshielded cables for AC voltage > 25 V and ≤ 400 V
Group 3:
unshielded cables for DC and AC voltages > 400 V
The following group combination can be routed only in separate
bundles or separate cable ducts (no minimum distance apart):
Group 1/Group 2
