The AC BTS3900E does not support installation on a tower, whereas the DC BTS3900E can be installed on a tower of 50 m. During the installation, installers cannot stand right under the BTS3900E to avoid being hit by dropping equipment. In addition, installer A on the tower must be careful in catching the equipment and untying the ropes to prevent the equipment from dropping off.
3. Lift the CPRI optical cable up to the tower. Procedure: 1. Cut off a 200 mm long corrugated pipe with the diameter of 25 mm. 2. Lead the fiber tails labeled 1A and 1B of the optical cable into the corrugated pipe by 160 mm. 3. Wrap the corrugated pipe and optical cable with the color tape. 4. For the tower made of steel pipes, tie the black jacket to the corrugated pipe at the position 150 mm away from the color tape, and then lift the optical cable up to the tower. 5. For the tower made of angle steel girders, carry the optical cable onto the tower when climbing up to the tower. 6. After the optical cable is lifted up to the tower, remove the color tape and corrugated pipe before installing the optical cable.
