
The bound cables should be kept close to each other and look straight and tidy, without sheath
damage.

The cable ties should face the same direction; the cable ties at the same position should be at the
same level.

After cables are installed, make sure to stick labels at two ends, intermediate connection positions,
and turning points of cables.

Lay out different types of cables separately. Prevent laid cables from twisting or crossing each other.
Power cord laying requirements

The power cord laying positions should comply with the engineering design drawing requirements.

If the power cord length is not enough during laying, replace the power cord. Do not make joint or
welding spot along the power cord.

Avoid circling or twisting when laying the power cord.
PGND cable laying requirements

Do not lead in the PGND cable from the outdoor overhead layer. It must be buried underground in the
whole course or routed indoors.

Do not bind the PGND cable and signal wire together or make them intertwined, and keep a distance
between them to avoid mutual interference.

All the accessible conductive metal parts in the device enclosure must be connected to the protection
ground terminal reliably.
Fiber laying requirements

Do not bind the fiber at the fiber bending position.

Do not pull the fiber forcefully or use a foot or other heavy objects to press the fiber, and prevent the
fiber from coming into contact with sharp objects, lest the fiber would be damaged.

When routing optical fibers, wind excess fibers on a special device, e.g., a fiber reel.

For the optical fiber jumper, the fiber must be bound with cable ties. If the fibers need to be fixed on a
cabinet or device, use cable ties for the optical fiber. Ensure that the fibers can be pulled freely in the
cable ties but cannot be bent to form a right angle.

Use uniform force when winding fibers. Do not force to bend fibers lest they would be damaged.

Be sure to put on a dust cap when the fiber connector is not in use.
