2.5 AC input power cable installation Installing AC Input Power Cables Procedure: Lay out an AC input power cable, and route it into the cabinet through the cable hole in the left part of the cabinet bottom. Find a spare(or new purchase and install) 3*25A(there-phase 25A) AC circuit breaker in AC box. Secure the AC input power cable to the corresponding AC input circuit breakers and terminal.
AC INPUT Circuit Breaker in Power System
3*25A Circuit Breaker in AC box
Note: If the AC box can’t reuse or re-install 3*25A breaker, only allow to
use single-phase breaker(at least 1*10A) for temporary precommissioning of BTS/MW, But should turn off the existing power system before swapping, and relocate Huawei power system AC INPUT to three-phase circuit breaker(3*25A). 16
2.6 Battery installation Installing Batteries Procedure: Install batteries into the battery compartment in the sequence.
Remove the insulation cover from the batteries. Install copper bars between batteries. Reinstall the insulation covers onto the two batteries in the middle.
Insulation Cover
Copper Bar
Take negative battery cables from the left side of the battery compartment, and connect the cables to negative battery terminals. After you install all negative battery cables, take positive battery cables from the right side of the battery compartment, and connect the cables to positive battery terminals. Reinstall the insulation covers onto the batteries on the left and right sides.

2.7 Power System Commissioning(1/2) 1. Connecting the AC Power Supply Procedure: Measure the input voltage on the AC input circuit breaker. The value should range from 85 V AC to 300 V AC. Switch on the AC input circuit breaker and measure the output voltage of the AC input circuit breaker. The value should range from 85 V AC to 300 V AC. Check that the indicators on the rectifiers are steady on. Measure the voltage between the -48 V busbar and the RTN+ busbar. The value should range from -42 V DC to -58 V DC. 2.

6. Connecting the Battery Supply Procedure: Switch off AC input circuit breakers. Switch on the battery circuit breaker, then switch on AC input circuit breakers. Switch all the circuit breakers to the appropriate status based on site requirements. Observe the power system for 15 minutes. If no alarm (excluding door alarms) is generated on the LCD during this period, the voltage and current for batteries and loads are normal. 19

3.4 How to measure the azimuth of ANT Be sure that the position of compass was put it correctly •Don’t test on the tower •Keep more than 2 meters from the tower •Keep the compass in horizontal •Make the compass in same direction with target antenna
horizontal
Step1: Make the mid-line of compass is same with the direction of Antenna Azimut h= the red value found on the compass via the observing hole Record the value.
Make the compass same direction with antenna
Read the Red number from the observe window (the first number)
Record and call OMC to confirm the azimuth value of all the sectors
24
3.5 How to adjust the down-tilt of ANT The HW Tri-band antenna length is 2.6 meters, should set mechanical tilt according to the marker of L=2.6
This small triangle using to define mechanical down tilt
Record and call OMC to confirm the M-tilt value of all the sectors
