Please comply with all warnings and operating instructions in this manual strictly. Save this
manual properly and read carefully the following instructions before installing the unit. Do
not operate this unit before reading through all safety information and operating instructions
carefully.
1 When Using battery
Danger of High Voltage：
The high voltage power supply offer the equipment power, wet object contact high voltage
power supply directly or indirectly , can cause fatal danger.
Using a special tool：
Working in high voltage and ac power, be sure to use a special tool instead of ind
ividual tools
Static-free：
Static electricity would damage veneer on the electrostatic sensitive components,
before touching the plug-in, circuit board or chips, be sure to use correct electr
ostatic prevention measures.
Disconnect the power supply in operation:
When operate the power supply, you must first cut off power supply, power operatio

n is prohibited.
DC short circuit dangerous：
Power system provides dc regulated power supply. Dc short circuit could cause fata
l damage to the equipment.
2 While Charging
CAUTION
The temperature range over which the battery can be charged is 0°C to 45°C. Charging
the battery at temperatures outside of this range may cause the battery to become hot
or to break. Charging the battery outside of this temperature range may also harm the
performance of the battery or reduce the battery’s life expectancy.
3When Discharging the Battery
DANGER
Do not discharge the battery using any device except for the specified device. When
the battery is used in devices aside from the specified device it may damage the
performance of the battery or reduce its life expectancy, and if the device causes an
abnormal current to flow, it may cause the battery to become hot and cause serious injury.
CAUTION
The temperature range over which the battery can be discharged is -20°C to 60°C. Use
of the battery outside of this temperature range may damage the performance of the battery
or may reduce its life expectancy.

6-3. Single battery Installation
Installation and wiring must be performed in accordance with the local electric laws/regulations
and execute the following instructions by professional personnel.
1) Make sure the mains wire and breakers in the building are in compliance with the standard
of rated capacity of battery to avoid the hazards of electric shock or fire.
NOTE: Do not use the wall receptacle as the input power source for the battery, as its rated
current is less than the battery’s maximum input current. Otherwise the receptacle may be
burned and destroyed.
2) Switch off the mains switch in the building before installation.
3) Turn off all the connected devices before connecting to the battery.
4) Put the terminal block cover back to the front panel of the battery.
6-4. Software Installation
For optional computer system protection, install battery monitoring software to fully configure
battery shutdown and other setting value.
6-5 Operation Instruction for Installation
1) Prior to installation, please check whether the battery is normal.
Press the reset key RST on the front panel for 3S for startup. During startup, 4 capacity indicator
lights on the front panel, ALM alarm indicator light (red) and RUN running indicator light
light up. Check whether all indicator lights light up normally; then the ALM alarm indicator
light goes out, the RUN running indicator light lights up and the capacity indicator light
lights up according to the capacity.
If the ALM alarm indicator light flashes after startup, it means that the battery has an alarm.
The newly installed battery seldom has alarm. The common alarm is the battery undervoltage

alarm (which is resulted from non-use of the battery for a long time). Such case may be removed
after the battery is charged for 30min; if the alarm may not be removed, please press the reset
key RST for 10S, until all LEDs light up for reset, execute the battery reset operation and
confirm whether the alarm is removed. If the alarm is removed, the battery may be used normally.
Otherwise the battery shall be reworked.
2) For the battery which is normal after detection, please press the reset key RST for 3S to
execute the battery ON/OFF operation.

Startup
In the OFF state of BMS, press the key for 3S for startup;
Shutdown
In the non-standby state of BMS, press the key for 3S for
shutdown;
Reset
In the non-standby state of BMS, press the key for 10S, until
all LEDs light up for reset.
Instructions: “Shutdown” and “standby” and “startup” and “activation” in Chinese have the same
meaning.
3) Installation of the lithium battery, wiring and startup.
Make the battery pack in a standby state, install it in the battery cabinet one by one, the
anode and cathode of the battery pack are connected respectively, which are connected to the
switching mode power supply or UPS (Please note that the switching mode power supply and UPS
shall be disconnected from the AC). Press the reset key RST of one of battery packs for 3S
for startup. Such startup battery may activate other batteries which are connected in parallel
(or press the reset key RST of each battery pack for 3S successively) and the whole battery
pack with high capacity enters the working state. Later, apply AC to the power supply equipment
such as switching mode power supply and UPS to make the whole standby system run.
The specification of the connecting line is selected according to the load current, with the
common specifications of the connecting line as follows:
