Figure 25 Cable binding example (1)
• Keep the cable bend radius at least twice the cable diameter, and at least five times the cable
diameter at a connector.
• Route and bind different types of cables (power cables, signal cables, and grounding cable)
separately in a cabinet. Where they are very close to each other, lay them in a cross way. In the
case of parallel cabling, keep the distance of at least 30 mm (1.2 in) between power cables and
signal cables.
• Make sure that all binding brackets and cabling troughs are smooth and free of any sharp edges.
• Make sure that metal cabling holes have smooth and rounded surfaces or furnished with an
insulating bush.
• Use the proper size cable ties, instead of joined ties, to bind cables. Presently, commonly used
cable ties are sized 100 × 2.5 mm (3.9 × 0.10 in), 150 × 3.6 mm (5.9 × 0.14 in), 300 × 3.6 mm
(11.8 × 0.14 in), 530 × 9 mm (20.9 × 0.35 in), and 580 × 13 mm (22.8 × 0.51 in).
• After binding the cables, cut the extra parts of the cable ties neatly, without any sharp points, as
shown in the following figure.

• Bind the cables before and after making a turn. To prevent cable breakage caused by excessive
stress, do not bind the cables within a bending area. See the following figure.
