facilitate the subsequent commissioning work are available.
Table 1 lists the check items for tools before the commissioning.
Table A-2 Charging devices and common tools
SN Item Description Purpose
1 Detection
device for
battery charge/
discharge or
system power
It is recommended that you use the
detection device for the battery
charge/discharge. If you do not have
the detection device, use the system
power compatible with the
communication device.
Used for the battery
supplementary charge and
the capacity detection.
2 Multimeter 0.5 level, three and half bits meter Used for detecting the
voltage of the battery group
and the voltage of the single
battery.
3 Clamp meter
Current precision ≤ 3%
Used for detecting the
charge/discharge current of
the battery.
4 Adjustable
spanner
- Used for tightening the
screw.
5 Flathead

A.3.2 Precautions
This topic describes the precautions to be taken during the battery supplementary charge.
Precautions
The precautions to be taken in the charge are as follows:
l For the battery supplementary charge, you need to use the dedicated device for the battery
charge/discharge. If the required condition is unavailable, you can also use simplified power
or directly use the system power of the offices. When using the simplified power or the
system power of the offices, you must properly set the charge/discharge parameters.
l The entire process of the battery supplementary charge needs to be monitored strictly.
Otherwise, abnormalities may occur.
l The connection point of the battery terminal should be clean, bright, and smooth. Before
connection, check and clean the terminal to reduce contact resistance and prevent
connection voltage drop from being too high.
l Prevent short circuit in the connection and insulate all the tools.
