4. If a number of wire terminals are connected to a multi-point connector,
provide slack and arrange them neatly to prevent stress on certain wires, as
shown in Figure 4-5.

5. Protect cable holes in a metal kit with grommet strips. Alternatively, ensure
that the holes are rounded, free from burrs or sharp edges.
6. Keep cables far away from heat sources such as radiators and heat vents. If
unavoidable, take heat resistant measures.
7. Keep cables far away from operating components such as fan blades and do
not bind cables to an
airow path of fans.
8. Prevent rotating components such as doors from squeezing or pulling cables.
Cable Binding Requirements
Bind cables reliably along the route and ensure that the binding interval meets the
requirements in Table 4-1.
Table 4-1 Cable binding interval
Cable Diameter (mm)
Binding Interval (mm)
< 10 150
10–30 200
> 30 300
1. Bind cables with a moderate force and ensure that cables are not misshapen
to prevent compromising the signal quality.
2. After binding cables, cut
o the excess parts of cable ties and trim away any
burrs, as shown in Figure 4-6.
