3. Lift the CPRI optical cable up to the tower.

Installers A climb onto the tower. Then, installer A fixes

the pulley to the support of the tower platform and leads

the lifting rope through the fixed pulley.

Installer C uses a lifting rope to bind the BTS3900Eand installation components as shown in the preceding

figure and then tie a knot in the steering rope at the

handle of the BTS3900E.

Installer B pulls the lifting rope, and at the same time,installer C pulls the steering rope away from the tower to

prevent the BTS3900E and installation components from

colliding with the tower.

Installers A hold the BTS3900E and installationｓcomponents and untie the ropes.

When lifting the BTS3900E up to the tower, bind theE1 cable, FE cable, and alarm cable with outdoor black

anti-ultraviolet cable ties.
