Cable Routing Inside and Outside of Cabinets:
The cables should be divided into the following groups to
guarantee a routing suitable for EMC:
Group 1: shielded bus and data lines,
shielded analogue lines,
unshielded DC-voltage lines
F 60 V,
unshielded AC-voltage lines
F 25 V,
coax cables for monitors.
Group2: unshielded DC-voltage lines > 60 V and
F 400 V,
unshielded AC-voltage lines > 25 V and
F 400 V.
Group3: unshielded lines for DC- and AC-voltage > 400 V.
Cable routing in common bundles or cable ducts is possible for the
following group combinations:
Group 1/Group 1; Group 2/Group 2; Group 3/Group 3
Cable routing in separate bundles or ducts (without a minimum
distance) is necessary for the following group combinations:
Group 1/Group 2
For the group combinations:
Group 1/Group 3; Group 2/Group 3
Cables must be routed along separate cable runs with a minimum
separating distance of 10 cm. This is valid for inside buildings and
for inside and outside cabinets in separate bundles and cable ducts.
