ET CDMA Phases II

1

Checking of Design

There are design documents, and the installation is accord with the design documents. 2 2.1

Site Environment Sealed Room for equipment

The doors and windows of the new shelter, the cable-through feeder window and holes leading outside, should be sealed properly. The holes leading outside of the outdoor site should be sealed properly, so as to keep water, dust, mice and insects from entering the room.

Sealed properly

2.2

Site Safety

There are no any flammable, explosive, corrosive, or heat producing object (such as paint, gasoline, and stove) in the site room. 2.3

Site clean

The room and the floor are cleaned when the site installation finished.

ET CDMA Phases II

2.4

Spare parts neaten

Spare parts, construction materials and other items should be neatly stacked .The sundries irrelevant to operation, like cartons or remnant cables or wastes should be removed or packed up.

2.5

Detection devices

There should be early fire detection devices，such as smog detector, temperature detector，in the equipment area. There should be fire extinguishers around.

2.6

Site safeguard

The ground must be even, there should be wall or fence around the site to protect. This is ETC's responsibility. 3 3.1

Civil work and grounding system and of the new site Civil work

The civil work and the concrete intensity should conform to the engineering design. This is ETC's responsibility. 3.2

Tower foot

The tower-foot should be encapsulated with cement and mortar without surface defects. This is ETC's responsibility.

Tower foot should be encapsulated with cement and mortar without surface defects

3.3

Earthing net and grounding system

Earthing net and grounding system construction should conform to the engineering design. 5 / 13

ET CDMA Phases II

This is ETC's responsibility. The cross joints between tower-foot and earth lead are welded properly without any loose or shaking. 4 4.1

Tower, generator, solar, shelter installation Installation accord with the design

The tower，generator, solar and shelter installation should conform to the design. 4.2

Tower anchor bolt

The anchor bolt above the foundation should be treated with anticorrosion and theft proof.

4.3

Shelter body

The shelter body should be installed properly and firmly on the groundwork without any deformation.

6 / 13

ET CDMA Phases II

4.4

Cable tray

The cable tray should be connected well, firmly.

4.5

Support bracket for the external Air Conditioner

The support bracket for the external AC (air conditioner) part should be installed properly and firmly.

7 / 13

ET CDMA Phases II

4.6

Generator or solar installation

All the bolts and nuts of the generator or solar must be fixed firmly without any loosening.

the blot of solar fixed firmly

5 5.1

Lightning Protection and Grounding Feeder grounding

The feeder should be grounded in an applicable way at the following three points: at the tower platform, in between the tower and the outdoor cable tray, 1m away from the feeder window outside. If the tower is over 60m high, the feeder should be grounded once more at the center of the tower. If the feeder is laid on the building roof, the feeder should be grounded at the following three points: 1m away from the antenna pole, 1m away from the roof platform, and 1m away from the entrance to the equipment room. 8 / 13

ET CDMA Phases II

5.2

Grounding cables Connect

Copper lugs should be used for the ends of the grounding cables. The surface between the lugs and the grounding bar should be attached tightness.

If the bolts are not enough, two grounding cables can share one bolt.

5.3

Outdoor anticorrosion

All the outdoor grounding bars and joints are treated with anticorrosion and rust-proof.

BTS Installation and wiring Equipment installation reliable

Equipment installation must fix to the ground and the fixing method should be reliable. 6.2

Cable routing

The routing of power cable, signal cables and GND cable should be straight and with proper addition at the bends..

6.3

Power cables

The copper lugs of the power cable must have a protective casing or wrapped. The power cable should be without any joint in between, and the insulating layer should be intact and sound. 6.4

BTS device

There are no sundries in the BTS Cabinet.

6.5

Label

The labels must be uniform and printed clear. The tail of these straps should be in the same direction. 12 / 13

ET CDMA Phases II

6.6

Antenna

The antenna model, azimuth and suspension height should conform to the design. The antennas, feeders, grounding cables shall be installed properly and firmly. 6.7

VSWR

The measured standing wave ratio should be smaller than 1.5. It is required to provide the corresponding VSWR value and the VSWR test diagram.
