3.Installation Notes
3.1 Tools
The following tools are required to install the battery pack：
Wire Cutter
Crimping
Modular Plier
Sleeve Piece
Screw Driver
Electric Screw
Driver
600VDC Multimeter
Notice！
Use properly insulated tools to prevent accidental electric shock or short circuit.
3.2 Safety equipment
The following safety equipment is recommended when handling the battery pack：
Insulated gloves
Safety goggles
Safety shoes
3.3 System operating environment check
3.3.1 Cleaning up of the environment
Before installation, the surrounding area should be made clean of dust and
iron filings.

- 11 -
Before the system is powered on, make sure that there are no flammable and
explosive objects around。
3.3.2 Installation Environment Requirements
System operating temperature range: 0℃～45℃; optimum temperature:
15℃～35℃。
Although there are no forced ventilation requirements for battery systems,
please avoid installation in restricted areas。
High salinity, high humidity or high temperature should be avoided in
ventilated areas。
The battery system needs to be installed indoors. In cold areas, it is necessary
to place the battery in an indoor environment not lower than 0 ℃.
The minimum clearance between the system and the heat source is greater
than 2m.
The system shall not be immersed in water. When installing the battery system,
we suggest that the bottom of the battery system should be 100mm~200mm
higher than the ground.
The ground where the battery system is installed must be able to support the
weight of the whole battery system (35~175kg).
Recommendations for the minimum clearance around the battery system:
more than 400mm at the top, more than 400mm at the left and right sides,
more than 600mm at the front and less than 100mm at the back against the
wall.

- 12 -
3.3.3 Fire extinguisher system
For safety, fire extinguishers must be equipped. Regularly check whether the
fire extinguisher is in normal condition.
It is recommended to choose carbon dioxide, ABC dry powder fire extinguisher
or Helen fire extinguisher.
The fire caused by over temperature of general cables and connectors is
controllable, but there is high voltage, so it is necessary to shut down the
system and then use the fire extinguisher to extinguish the fire.
If the fire is caused by batteries, you must leave the site and call the local fire
department for treatment.
3.3.4 Grounding system
Before installing the battery, make sure that the grounding point in the base is
stable and reliable. If the battery system is installed in a separate equipment
compartment (such as a container), it must be ensured that the grounding of
the compartment is stable and reliable.
The resistance of the grounding system must be measured <4Ω.
3.4 Handling and placement
The power terminal of the battery pack is high-voltage DC, which must be
handled and placed by special personnel.

- 13 -
3.5 System installation
Note: Batteries exist in groups, and the same group number must be selected
during installation. Mixing batteries with different group numbers will affect
the battery performance.
3.5.1 Grouping
The battery module will be divided into different gears according to the battery
capacity. The capacity of different gears is slightly different, but they are within the
normal range of the rated capacity. The battery module composition system of the
same gear can improve the use efficiency of the battery. The gear identification is
shown in the figure below, on the right side of the battery box. The gears are not
limited to ① and ②, and the pictures are for reference only.
3.5.2 Side cover removal
There are 4 holes on the side cover. Insert a screwdriver along the holes to loosen
the screws that fix the side cover. After loosening the 4 screws, lift the side cover
straight.
3.5.3 Stacking and fixing of battery modules
Accessories required for battery module fixing.
Note: Accessories are supplied with the battery pack and do not need to be
purchased separately.

The high voltage batteries of the SP-HEHV27 series can be formed into 5
different systems. The way they are stacked and fixed is the same.
The battery box fixing parts are installed, and the left and right sides are
installed symmetrically to ensure a stable installation of the system.

- 15 -
Install the L-shaped fixing between the control box and the battery box. The
opening of the L-shaped fixing is a rectangular hole, which can be adjusted
from 0 to 20mm according to the distance between the battery system and the
wall. The L-shaped fixings are also installed symmetrically from left to right.
After adjusting the position of the battery system, mark the position of the
fixing hole of the L-shaped fixing on the wall.
Remove the L-shaped fixing, remove the control box, and make a hole in the
wall. When drilling holes, cover the battery well.
Drill size: hole diameter 10mm, depth 60mm。

- 16 -
Fix the two L-shaped fixings on both sides of the battery box and the control
box, and then fix them on the expansion bolts on the wall。
3.6 Wiring
DANGER: The battery system is a high-voltage DC system. It must be ensured that
the grounding is secure.
DANGER: All power cable plugs and sockets must not be reversed. Otherwise it will
cause personal injury.
WARNING: Incorrect communication cable connection will cause battery system
failure.
