1.2 PICTURES
Antenna should be fixed well
waterproof self-conglutina
remark: waterproof self-conglutinant adhesive tape should be covered carefully to make sure the function available.
2. FEEDER CABLES
R>400mm
remark: the radius should be more than 400mm
remark: The normal distance between cable clips should be 3 steps on the cable tray. But in the picture ,it is 2 steps.
remark: Pay attention to the cable radius. It is should be more than 400mm.
remark: the lighting arrestor installation
C B A
remark: A: CELL 1 ; B: CELL 2; C: CELL 3 The antenna degree according to the survey report.
3. BATTERY INSTALLATION
remark: when we install the battery, we should not put any tools or iron sticks on the battery, it is very dangerous. battery temperature sensor
remark: each battery should be connected to one sensor, pay attention to the sequence.
remark: battery cables arrangement
4. DDF INSTALLATION E1 CABLE AND GND CABLE
remark: one E1 cable including 8 cores,4 pairs. The SN 1,2,…8. for instance,1,5 is the first pair ,2,6 the second pair for 1E1.in the picture, the ground cable was not connected yet.
5. RACKS INSTALLATION
remark: the face of the two racks should be the same plane. In this site, there are one rectifier rack
and one BTS rack.
6. BTS POWER CABLE INSTALLATION
0V(BTS MARK:GND) :BLACK COLOR; -48V(BTS MARK:PWR):GREEN COLOR
7. AC DISTRIBUTION BOX
AC CABLE
remark: for equipment installation, we just need to consider the AC cables
8. GROUND CABLES There are two GND systems. One for antenna and feeder cables, the other for inside equipment(inside earthing system).
8.1 Inside eathing system Input
Inside earthing system input bar
Connect to earthing system
remark: in the shelter, the two ground bars should be connected with cable( ).this two ground bars are just for the equipment. All of the equipment ground cables should be connect to the two
ground bar. When we install the GND cables, we should confirm the cable diameter and the length and the color.
8.2 outside earthing system antenna and feeder cable and tower earthing system
GND 1
GND 2
OUTSIDE GND BAR
GND 3
ARRESTOR GND CABLE (TO OUSIDE GSNBAR)
