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. dis-
tance of 10cm.
[4]
The lines have to be installed in different bundles or cable
trusses with a min. distance of 50cm.
