Separate AC and DC power cables from diverse non-shielded signal cables.
Keep the cable spacing greater than 100 mm or use grounded metal for
isolation purposes. Do not bind the cables together. Preferentially route the
cables along different sides of cabinets.
You are advised to route network cables and optical cables separately.
Unless otherwise specified in a design file, ensure that the bend radius (R) of
a cable meets the following requirements:
– Common cable: R ≥ 3d
– Optical cable: R ≥ 40 mm
NO TE
R indicates the bend radius, and d indicates the cable diameter.
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 4-51 Cable connection positions
Before installing a semi-flexible cable, use a dedicated tool to curve the cable.
Do not curve the cable while holding the cable connector by hand.
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 4-52.

Protect cable holes in a metal kit with grommet strips. Alternatively, ensure
that the holes are rounded, free from burrs or sharp edges.
