– Common cable: R ≥ 3d
– Optical cable: R ≥ 40 mm
R indicates the bend radius, and d indicates the cable diameter.
2. Reserve slack at cable connection positions to facilitate connection and
disconnection and to prevent stress. Do not leave the cables tight and prevent
connector misalignment, as shown in Figure 4-181.

3. Before installing a semi-exible cable, use a dedicated tool to curve the cable.
Do not curve the cable while holding the cable connector by hand.
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 4-182.

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
airow 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 4-12.
