2.4 Requirements for Cable Routing
Cables should be more than 20 mm away from heat sources to prevent insulation layer
damage (melting) or functional degradation (aging or breakage).
The bending radius of cables should be at least five times the diameter of the cables.
Cables of the same type should be bound together. Cables of different types should be a
minimum of 30 mm from each other to avoid tangling.
Cables that are bound together should be close to each other, tidy, and undamaged.
Ground cables must not be bound to or tangled with signal cables. There should be an
appropriate distance between them to minimize interruptions.
AC power cables, DC power cables, signal cables, and communications cables must be
bound separately.
Power cables must be routed straight. No joints or welding should be performed on
power cables. Use a longer cable if necessary.
