Cable Spacing Requirements
Comply with the following requirements if possible to lay out different types of cables:
1. 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.
2. Network cables and optical cables are recommended to be routed separately.
Safety and Reliability Requirements for Routing and Binding Cables
1. 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
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 4-4.

3. 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.
