Lifting the RRU and Installation Components to the Tower, as shown in

the following figures.

1. 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 pulley.

2. Installer C uses a lifting rope to bind the

RRU and installation components as shown inthe preceding figure and then tie a knot in the

steering rope at the handle of the RRU.

3. Installer B pulls the lifting rope, and at the

same time, installer C pulls the steering rope

away from the tower to prevent the RRU and

installation components from colliding with thetower.

4. Installers A hold the RRU and installation

components and untie the ropes.

RRU Fixation at tower

The RRU will be installed at the approved

height of site design. It may be installed by

installing additional pole on tower angle or

behind the GSM antenna. Feeder length

from GSM antenna to RRU will be as

close as possible. And the length of RRU

pole (if used) will be 1.5 m. The groundingof RRU will be 35 rm Al or 25 rm Cu. In

case of RRU installation at more than 35

m of tower, RRU will be installed inside or

outside of tower angle. It will be subjected

to the field condition whether there is free

space available on tower or not. Adequate

mounting kit will have to be used during

RRU installation.

CAUTION: When a dual-polarized antenna is shared by two RRUs in the same sector, the two RRUs are connected through

an inter-RRU jumper. The connections of three RRUs in the same sector are not supported.




48/53


Cable Connections of RRUCAUTION:

1. Press the strap on the exposed shielding layer of the power

cable tightly. Ensure that the lower edge of the exposed shield

layer does not exceed the position shown in the figure.2. The shielding layer of the other end of the power

cable should be grounded.

3. When the alarm cable is connected, ensure that the

shielding layer of the alarm cable on the RRU side is

exposed and that the shielding layer is tightly pressed

by the strap.4. The alarm cable is preferably led out of the RRU

from the narrower cable trough in the middle of the

cabling cavity. If the cable trough is used by the CPRI

optical cable, the alarm cable is led from the wider

cable trough near the middle one. In this case, the

alarm cable must be wrapped with 10 to 17 layers of

waterproof tape so that the diameter of the cablereaches 10 mm to 12 mm.

5. To avoid sharp bending, the optical cable must be

pressed by the strap next to the power cable during

the optical cable installation.
