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.
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 individual tools.
1.Safety Precaution

4
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 electrostatic prevention measures.
Disconnect the power supply in operation:
When operate the power supply, you must first cut off power supply, power operation is prohibited.
Dc short circuit dangerous：
Power system provides dc regulated power supply. Dc short circuit could cause fatal damage to the
equipment.
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.
When 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.

4-5. Installation of Battery in Parallel
4-6. Installation Precautions
(1) Prior to installation, unpacking to check the quantity of the parts and battery appearance.
(2) Different brands of batteries or new and old batteries cannot be used in parallel.
(3) Static voltage differences ≤ 0.2V, SOC differences ≤ 5%, internal resistance differences ≤ 2mΩ can be
used together in parallel.
(4) Install the hanger and handle and measure the battery voltage with a multimeter. The general factory
voltage of the battery is 48V-50.25V.
(5) Prior to wiring, check the anode and cathode of the battery and the anode and cathode terminals shall not
be connected reversely.
(6) During battery connection, please wear the protective gloves. When using such metal tools as torque
wrench, please perform insulating packaging for them and two end of the metal tools such as torque
wrench shall not contact the positive and negative terminals of the battery at the same time to avoid
battery short-circuit.
(7) Before the battery is connected with the externally connected equipment, make the equipment in a
disconnected state, check whether the connecting polarity of the battery and total voltage are correct,
connect the battery anode with the equipment anode and battery cathode with the equipment cathode
and fix the connecting line.
(8) During handling and placement, the battery must be handled gently. No dropping or impacting. The
battery shall not be thrown or beaten to avoid damaging the battery or resulting in potential safety hazard.
(9) Do not touch the surface of the battery box with the sharp part of the tool to scratch or damage the
battery box.
(10) Do not disassemble the battery box without authorization.

(11) Do not put any article made of the metal conductive material together with the battery or assemble it into
the battery box.
(12) Install it according to the selected installation mode:
Installation of standard cabinet (rack): Install the matching hanger for the battery pack and fix them
in the standard cabinet and the tray protection is added for the battery box.
Installation of wall-mounted box: Prior to installation, please ensure that the wall complies with the
wall-mounted requirements; according to the location in the design plan, install the special wall-mounted
box of the lithium battery; the battery pack is fixed in the wall-mounted box in a hanger manner.
Installation of integrated indoor and outdoor cabinets (boxes): Install them according to the
installation specification for the customized integrated cabinet (box).
4-7. 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 for3S
to execute the battery ON/OFF operation.

Instructions: “Shutdown” and “standby” , “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, it is
suggested to select 35mm2 copper wire. (connection line 1/1pcs) 1000mm.
(connection line 2/1pcs) 1000mm
Introduction to operation steps in detail according to the capacity required:
• Battery pack in parallel (the wiring diagram is shown in Figure 1 or Figure 2):

19
Step 1: Make the battery pack in the standby state and install it in the wall
successively.
Step 2: Disassemble the anode insulating cap of the neighboring batteries one by one, connect
the anodes of up and own neighboring battery packs with the installation connecting line and screw
on the anode insulating cap.
Step 3: According to step 2, connect the cathode of the battery pack.
Step 4: Set the dial-up addresses of all battery modules from top to bottom one by one, which
are 1000, 0100, 1100 and 0010 (the dial-up addresses are set according to the number of battery
modules actually used) respectively; (this step may be skipped if there is no need to access to the
remote monitoring platform).
Step 5: Perform the cascade connection to RS485 communication interface of the battery
module with the RS485 connecting line; lead to the collector of the monitoring platform from the
RS232 interface of the battery module with the address of 1000 with the RS232 connecting line; (this
step may be skipped if there is no need to access to the remote monitoring platform).
Step 6: Draw out two wires from the anode and cathode of a battery pack at the top or in the
middle respectively as the main connecting line of the battery pack in parallel, which are connected
with the switching mode power supply or UPS.
Step 7: Press the RST key of each battery pack for Reset and the whole battery pack with high
capacity enters the working state.
