5.4.1 Cable Routing Rules
Binding Cables
Table 5-3 Cable binding rules
No. Cable Binding Rule
1 Power cables and signal cables are bound separately with a distance above
150 mm.
2 Both ends of a cable are labeled. Labels are clean and correct, and provide
concise and understandable description.
3
Cable ties are neatly cut without sharp burs, evenly distributed, bound to a
proper strength, and fastened towards the same direction if possible, as
shown in
Figure 5-14 and Figure 5-15 .
4 Each output power cable bundle can contain 5-10 cables. If too many
cables are bound together, the cables may overheat due to poor heat
dissipation.
5 Extra cables are coiled neatly and easy to find.
6 Cables on the surface of a large cable bundle are neatly organized without
unnecessary crossover.
7 Cables are arranged in distinct layers and crossovers are avoided if
possible when cables in different colors are bound together, as shown in
Figure 5-16 . Cables are arranged by thickness when arrangement by
thickness conflicts with arrangement by color.
8 Cables are reliably bound along the route, and the binding interval meets
the requirements in
Table 5-4 .
9 Cables are away from sharp components such as copper bars and terminals
to avoid scratching.
