2) Cabinet Installation

2.1 Concrete base installation

2.1.1 Pre-concrete base, shown in the following figure 

Concrete Base and Installation Holes

Plinth（L×W×D）750mm×300mm×300mm，leaving the 570mm×300mm×180mm  cable introducing hole in the middle of the base.

2.1.2 Fixed with the expansion bolt, to ensure the screw center distance is 612mm×530mm.

2.1.3 Put the cabinet above the concrete base. The fixing holes and the base mounting holes should be placed in alignment, then locked, the cabinet and the concrete base should maintain vertical.

2.2 When the FDC is aerial installation, the company should provide the FDC platform.

3) Application and Maintenance

 3.1 Working principle of the optical cross connecting cabinet, shown in figure 3:

3.2 Optical cable fixing and grounding.

3.2.1 The optical cable get into the equipment from the cable introducing hole at the bottom of the cabinet then to the cable grounding and protection device.

3.2.2 The cable is stripped before the hoop fixed point at about 100mm, then be protected with the protection tube, to ensure the stripping length is 800mm~1000mm.

3.2.3 Get the cable with the armored layer fixed on the plate with a hoop,

and get the central strength member fixed on the grounding copper bar.

3.2.4 Get the earth wire connected with the cable fixing plate and then get it 

connected with the earth wire of the machine room.

3.3 The material of the baseplate is flame-resistant rubber bushing, be applicable for cables with different diameter. The diameter of the rubber bushing should be more than 2mm bigger of the diameter of the introducing cable.

3.4 The stripped cable was protected with the snakelike flexible tube, and been fixed with the wire loop on the installation plate, at last, introducing the cable into the fiber welding and distribution integration tray with the fiber natural bending radius.

3.5 Before fiber fusion, get the fiber into the protection tube, then get the optical cable fiber end face fused with the pigtail fiber end face according to the optical cable fusion technology, and then get the fiber coiled in the fiber welding and distribution integration module. (Each disk can weld 12F)

4) Packing/Transportation and Storage

4.1 Packing：The packing of the equipment conform to the product packing standard, which is moisture proof and sun-proof. The accessories and the backup are packaged in other bags.

4.2 Transportation：This equipment is applied to all the transportations, during the transportation, the ambient temperature is -40℃~+60℃, the relative humidity ≤95％（+30℃）, when the temperature is over +30℃ or in the rainy days, there should be a cover to avoid directly exposure to the sun and the rain.
