2. FEEDER CABLES
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.
R>400mm

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.
remark: each battery should be connected to one sensor, pay attention to the sequence.

4. DDF INSTALLATION
E1 CABLE AND GND CABLE
![Page 12: BTS Installation](https://reader033.vdocuments.fr/reader033/viewer/2022051208/5465b2e1b4af9fe1048b4789/html5/thumbnails/12.jpg)
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

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).
