Figure 1 Correct and incorrect cable binding
•
When you bend cables, bind cables as shown in Figure 2 . To avoid cable core break due to
excessive stress, do not tie up the cables in the bending area. The cable bend radius at
connectors must be a minimum of 5 times the cable diameter, and must be a minimum of twice
the cable diameter away from the connectors.
Figure 2 Binding the cables
•
When you route cables through sharp sheet metal penetration points or along sharp edges of
mechanical parts, use bushings or take any other action to protect the cables from being cut or
abraded. The sheet metal penetration points must be smooth and fully rounded.
•
When optical fibers are inserted into a protective tube, wrap tapes around the edges of the
protective tube to protect optical fibers from being cut.
•
After binding the cables, cut the excess from the ties, leaving no sharp or angular tips. See
Figure 3 .
