Summary

This part describes:

●Environment check prior to the BTS installation;

●Tool and instrument preparation prior to the BTS installation;

●Technical document preparation prior to the BTS installation.

2.1Installation Environment Inspection

Conduct the environment inspection prior to the installation. The basic inspection items are as follows:

Before the project installation, the customer should prepare the equipment room, power supply and grounding cable, and provide necessary facilities for the project implementation. The area and height of the equipment room should satisfy the requirements of the equipment layout. Otherwise, reconstructions are required to eliminate the hidden dangers in the installation, operation and maintenance of the equipment.

2.1.1 Inspection of the Equipment Room Building

The items for the equipment room building inspection are as follows:

1.The civil engineering of the equipment room and corridor has been completed, and the wall is fully dry.

2.The height and width of the doors in the equipment room should not cause any inconvenience for transporting the equipment. Usually, the height of the main doors in the equipment room should be no less than 2.2 meters, and the width should be no less than 1 meter. The net height of the equipment room should be
