4.3 Safety Gear
It is recommended to wear the following safety gear when dealing with the battery pack.
5 Installation instructions
5.1 Installation Precaution
Lithium battery is designed for outdoor use (IP65). But please avoid direct sunlight, rain ex-
posure, snow laying up during installation and operation.
Make sure that the installation location meets the following conditions:
 The installation area shall avoid of direct sunlight.
 The floor and walls are completely water proof.
 The wall is flat and level.
 There are no flammable or explosive materials.
 The ambient temperature is within the range from -20°C to 50°C. Not in the cool air directly.
 There is minimal dust and dirt in the area.
 The distance from heat source is more than 2 meters.
 The distance from air outlet of inverter is more than 0.5 meters.
 Do not place at a children or pet touchable area.
 There are no mandatory ventilation requirements for battery module, but please avoid of in-
stallation in confined area. Do not cover or wrap the battery case or cabinet.
 The aeration shall avoid of high salinity, humidity, or temperature. Not in environment of
precipitation or humidity (>95%).
 Not higher than altitude of about 2000 meters above sea level.
CAUTION
Cleaning. Before installing and powering up the system, dust and iron filings must be removed
to keep the environment clean. The system cannot be installed in desert areas without a shell to
protect against sand.

~ 13 ~
CAUTION
Temperature. If the ambient temperature is outside the operating range, the battery pack stops
operating to protect itself. The optimal temperature range for the battery pack to operate is 15°C
to 35°C.
Frequent exposure to harsh temperatures may deteriorate the performance and life of the bat-
tery pack.
CAUTION
Fire extinguisher system. For safety, it is best to have a fire extinguisher system. The fire protec-
tion system needs to be checked regularly to keep it in normal condition. For use and mainte-
nance requirements, follow local fire equipment guidelines.
CAUTION
Grounding system. Before the battery is installed, it must be determined that the basement
grounding point is stable and reliable. If the battery system is installed in a separate equipment
compartment (such as a container), the grounding of the cabin must be stable and reliable.
The resistance of the grounding system is not less than 0.1Ω
CAUTION
Handling and placement. The weight of the single battery module is 53kg. If there is no han-
dling tool, at least 2 persons must carry it.
The battery module must be installed by at least two persons using movable handles.
The PDU and Base are light to handle and place and can be installed by a single person.
5.2 Install the Battery
CAUTION
Remember that this battery is heavy! Please be careful when lilting out from the package.
The battery module must be installed by at least two persons using movable handles.
5.2.1 Selection of installation sites
It is necessary to choose the appropriate installation site according to the requirements of 5.1.
The system must not be immersed in water. The battery base should not be placed in rain or
other water sources. It is recommended that the height of the base is 300mm from the ground,
and the weight of the base should be able to support the weight of the entire battery system
124kg~336kg.
The installation location is recommended to meet the size requirements of the figure below：

~ 14 ~
5.2.2 Unpacking order
First open the box of the System Power Distribute Unit packaging box, take out the base and
handle, the handle is used to carry the battery module, without the handle the battery module
will be difficult to remove from the battery box.
5.2.3 Installation order
i. Put the installed base and feet along the wall, and keep the distance of 10~35 mm be-
tween the wall and the base.
ii. Open the battery box, take a battery module from the package out. Put one battery mod-
ule on the base. Pay attention to the direction of the module to make sure that the blind-
mating connectors of the module and the base are at the same side.

~ 15 ~
iii. Repeat the operations for other battery modules.
iv. Install the wall fixing plate (PDU part) to the PDU. To do this, follow the instructions below
to install and tighten them on the back side of PDU (torque: 2 Nm).
v. Put the PDU on top of the battery modules.

~ 16 ~
vi. Fix the upper and lower fixing plate connection between the battery module and the base,
between battery modules, and between PDU and battery module. To do this, insert the
screws (M4x12) through the holes on them, using a Hexagon Wrench (2.5mm) and tighten
them (torque: 2 Nm).
vii. Hold the wall fixing plate (wall part) where it intends to be mounted on the wall and mark
the position of the drill holes. Please pay attention that there may be power cables or other
supply lines (e.g., gas or water) routed inside of the wall. Ensure that no lines are laid in the
wall, which could be damaged when drilling holes.
viii. Set the wall fixing plate (wall part) aside and drill the marked holes. Choose the recom-
mend drill head (10mm) to drill 2 holes on the wall,100mm-110mm deep. Put the wall fixing
plate (wall part) in front of the holes, then insert the expansion screw of M6*100 and tighten.
ix. Fix the two hangers (wall part and PDU part) with M4X12 screws, using a cylinder screw-
driver (10 mm) to tighten it (torque: 2 Nm).

5.3 Electrical Connection
5.3.1 Single Battery System (It is suitable for scenarios where the inverter power ≤
12kW)
CAUTION
It should be noted that the maximum current of single battery system is 250A (inverter
power must not exceed 12kW), exceeding 250A will cause heating of the connectors and
cable, and in severe cases, it will cause a fire accident.
If the inverter power exceeds 12kW, the connection mode must be used Multiple Battery
System !
