Using the cables in the cable carrier
Note
When laying cables, carefully observe the instructions given by the cable carrier
manufacturer!
To maximize the service life of the cable carrier and cables, cables in the carrier made from
different materials must be installed in the cable carrier with spacers.
The chambers must be filled evenly to ensure that the position of the cables does not
change during operation. The cables should be distributed as symmetrically as possible
according to their mass and dimensions.
If possible, use only cables with equal diameters in one chamber. Cables with very different
outer diameters should be separated by spacers.
The cables must not be fixed in the carrier and must have room to move. It must be possible
to move the cables without applying force, in particular in the bending radii of the carrier.
The specified bending radii must be adhered to. The cable fixings must be attached at both
ends at an appropriate distance away from the end points of the moving parts in a dead
zone.
A tension relief must be installed at least at the ends of the cable carrier. Be sure to mount
the cables along the casing without crushing them.
The cables are to be taken off the drum free of twists, i.e. roll the cables off the drum instead
of taking them off in loops from the drum flange.
