Safety Information

High Voltage Series | Installer Manual7
WARNING
Improper use of the battery energy storage system can lead to death. The use of the battery en-
ergy storage system beyond its intended use is not allowed, because it may cause great danger.
Improper handling of the battery energy storage system can cause life-threatening risks, serious
injury or even death.
CAUTION
Improper use can cause damage to the battery cell.
Do not expose the battery module to rain or soak it in liquid.
Do not expose the battery module to a corrosive environment (such as ammonia and salt).

TRANSPORT TO THE END CUSTOMERS
Provisions on Shipping of Battery Modules
It is necessary to comply with the relevant regulations and provisions on roads for shipping lithium-ion prod-
ucts in the corresponding countries.
WARNING
It is prohibited to smoke in the vehicle during transportation or in the vicinity during loading and
unloading.
The dangerous goods transport vehicles shall meet relevant regulations concerning road trans-
portation and shall be equipped with two tested CO2 re extinguishers.
It is forbidden for the freight forwarder to open the outer package of the battery module. Use only
approved lifting equipment to move the battery cabinet system. Use only the hanging lug on the
top of the battery cabinet as the connection point. When lifting, the angle of the sling must be at
least 60°.
Improper vehicle transportation can cause injury. Improper transportation or improper transpor-
tation locks may cause the load to slip or overturn, resulting in injury. The cabinet shall be placed
vertically to prevent it from sliding in the vehicle, and a xing belt shall be used.
A tilting of the battery rack may cause injury. The maximum weight of a single battery rack of
High Voltage Series Battery can reach 628 kg. When tilted, they may overturn, causing injury and
damage. Ensure that the battery cabinet is on a stable surface and that it does not tilt due to load
or force.
The battery energy storage system can be damaged, if not properly transported. The battery mod-
ule can only be transported vertically. Note that these parts may be top-heavy. Failure to follow
this instruction may result in damage to the part.

High Voltage Series | Installer Manual8
Check whether the delivery is complete.
WARNING
During transportation, the battery storage rack may be damaged when it is installed with the bat-
tery module. The battery storage rack is not designed to be transported with the installed battery
modules. Always transport the battery module and the battery rack separately. Once the battery
module is installed, do not move the battery rack, and do not lift it by a lifting device.
If possible, do not remove the transport packaging before arrival at the installation site. Before
removing the transport protector, check if the transport packaging is damaged, and check the im-
pact indicator on the outer packaging of the battery converter. If the impact indicator is triggered,
the possibility of transport damage cannot be ruled out.
Improper transportation of battery modules may cause injury. The single battery module weighs
44 kg. If it falls or slips, it may cause injury. Only use suitable transport and lifting equipment to
ensure safe transport.
Wear safety shoes to avoid the danger of injury. When transporting the battery rack and battery
module, their parts may be crushed due to their heavy weight. Therefore, all persons involved in
transportation must wear safety shoes with toe caps. Please observe the safety regulations for
transportation at the end customer's site, especially during loading and unloading.
During transportation and installation of unpacked battery storage cabinets, the risk of injury in-
creases, especially on sharp metal panels. Therefore, all personnel involved in transportation and
installation must wear protective gloves.
The maximum weight of a single rack of High Voltage Series Battery can reach 628 kg. We suggest
that at least 2-3 people work together to install the battery rack. The lifting device is helpful for
heavy parts, and the pulley or cart for light parts. Be careful not to damage the case. The number
of battery modules stacked shall not be more than 8.

Battery Module Installation on Rack
1. Install the lug on the battery module and high-voltage control box.
2. Insert the rst battery module into the battery module rack at the bottom cluster rack; then in the order
from bottom to the top, continue the instalment in the same way till it reaches the twelfth oor. On the
thirteenth oor, insert the slide of the cabinet at the top of the rack into the high-voltage control box.
3. After the battery module and control box is inserted into the rack, use M4*12 outer hexagon cross com-
bination screws to x all the lugs of the battery module and control box on the side beam in turn.
4. After the battery module is placed in the control box, take out a 140 mm communication cable to con-
nect the communication port of the battery module and the high-voltage control box, and 11x110mm
communication cables to connect the battery module communication port (IN-OUT) from top to bottom.
(12 communication cables in total). The communication port (OUT) of the battery module at the
bottom is not connected to the communication cable. Instead, this port is sealed with a 120ohm
terminal resistor.
5. Take out a 220 mm positive power cord and connect the positive pole of the battery module at the top
to the positive pole of the high-voltage control box. Take out 11x200mm battery module power cords
and connect the power ports (B- to B+) in a top to bottom order to form a series circuit. For aesthetics,
connect the negative power pole of the rst battery module to the negative power pole of the high-volt-
age control box from the bottom of the battery module to the back of the rack. On the back of the rack,
a plane-head-shaped tie is used to secure the cable harness. (12 power cords in total).
6. Take out the external positive power cord EPCable5.0 and external negative power cord ENCable5.0, and
plug them into PCS interfaces, respectively.
7. Take out the ground wire A and connect one end of it to the M4 rivet nut of the high-voltage control box
panel, and the other end to any M6 screw hole of the cross beam above the rack. Take out the ground
wire B (user need to prepare in advance) and connect one end of it to any M6 screw hole of the cross
beam under the rack, and the other end to the customer's grounding point. (The length of the ground
wire B is determined based on the customer's condition.)
PLEASE NOTE
Before installing the battery, please turn the manual switch of the high-voltage control box to the o
position.
DANGER
Insucient or no grounding may cause an electric shock. Device malfunctions, and insucient or no
grounding may cause device damage and life-threatening electric shocks.
High Voltage Series Battery Startup Steps
After connecting the battery cables, press the air switch button on the high-voltage control box to turn OFF
to ON, and then press the START button. After the screen lights up, wait for about 8 seconds until the yellow
HV light indicator comes on. (The specic working time is subject to the HV light indicator's lighting-up time.)

In the factory conguration, the high-voltage control box is supplied with working voltage from an internal
power supply unit. If your plan requires an external 12V power supply, an adaptive version and a high-volt-
age control box can be provided as requested. Please contact our after-sales service personnel for details.
