Common Requirements for Installing, Laying out, and
Bundling Cables
The space between power cables, network cables, and optical fibers must be greater than 30 mm.
Power cables, network cables, and optical fibers cannot be interleaved but must be routed in parallel or separated with specific stuffs.
When cables are fixed or bound, the interval between two cable ties cannot exceed 40 cm.
When cables are bent, the bending radius is recommended to be greater than 60 mm and cables are not bundled at the turning
points.
The bending radius of optical fibers is no less than 40 mm. Do not pull, press, or squeeze optical fibers during installation.
Gently coil excess optical fibers. Do not forcibly bend the optical fibers.
Do not power on the device when installing and laying out cables.
