Content of this section is the line routing of bus, signal and supply lines. Object of the line
routing is to suppress the "slurring" at parallel lines.
For an EMC-equitable routing of the lines it is convenient to divide the cables in different
groups and install each group itself:
Group A
n screened bus and data lines
n screened analog lines
unshielded lines for direct voltage £60V
n
unshielded lines for alternating voltage £25V
n
n Coaxial cables for monitors
Group B
unshielded lines for direct voltage >60V and £400V
n
unshielded lines for alternating voltage >25V and £400V
n
Group C
unshielded lines for direct and alternating voltage >400V
n
Group D
n Lines for H1 respectively TCP/IP
Following the table you may see the conditions for the cabling of the line groups by com-
bining the single groups:

[1] The lines may be installed in common bundles or cable trusses.
[2] The lines have to be installed in different bundles or cable trusses (without min.
distance).
[3] The lines have to be installed in different bundles or cable trusses inside of
cubicles and outside of the cubicle but inside the building in separated cable
trusses with a min. distance of 10cm.
[4] The lines have to be installed in different bundles or cable trusses with a min.
distance of 50cm.
Wherever possible, exterior cabling should be installed on metallic cable trays. A galvanic
connection must be provided for joints between cable trays. You must abide by the appli-
cable lightning protection and grounding regulations when installing exterior cables.
