The bending radius of a 1/4'' jumper, a 1/2'' softer jumper, and a 1/2'' common jumper must
be longer than 35 mm, 50 mm, and 127 mm, respectively.
The bending radius of a power cable is at least three times the diameter of the cable.
The bending radius of a signal cable must be at least five times of the diameter of the cable.
Cables of the same type are bound together.
Different types of cables must be separately routed with a minimum spacing of 30 mm and
cannot be entangled.
The cables are bound tightly and neatly and the sheaths of the cables is intact.
The cable ties face the same direction and all cable ties bound at similar positions must be
in a straight line.
The extra length of each indoor cable tie must be cut off. A slack of 5 mm is reserved for
each outdoor cable tie before the extra length is cut off. All cut surfaces are without sharp
edges.
Labels or nameplates are attached to both ends, joints, or turns of cables after they are
installed.
Cables are placed away from sharp objects or wall burrs. If these positions are inevitable,
protection pipes are required for the cables.
Cables are routed away from heat sources, or heat-insulation materials are added between
cables and heat sources.
A clearance is reserved at turns of a cable or the position close to a device, facilitating cable
and device maintenance. The recommended clearance is about 0.1 m.
A maximum of 100 Ethernet cables can be bundled if no PVC pipes are used. If pipes are
used, a maximum of 24 Ethernet cables can be led through a pipe. In this case, ensure that
1/3 space inside the pipes must be vacant.
