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
(1 1.8 × 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.
Figure 26 Cable binding example (2)
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.
