1.4 Emergency handling
Wear personal protective equipment (PPE) such as goggle, face mask, insulated gloves and boots.
Evaluate the situation before taking remedy action. When it is safe to do so, disconnect external AC or
DC power connection.
Damaged or deformed battery enclosure
Risk of chemical leakage (i.e. electrolyte) and internal short-circuit.
Warning
Deformed or severely damaged battery pack can lead to piercing of cell pouch (chemical leakage) or
internal short-circuit (thermal runaway). The damaged battery pack can release toxic gas.Keep away
from it.
In case of accidental skin contact, wash the skin thoroughly with soap and seek medical advice. For eye
contact, wash under running water (~15 minutes) and require immediate medical attention.
Fire hazard
If the fire is not from the battery or not spread to the battery, please use FM-200 or CO2fire extinguisher
to put out the fire.
If the battery pack catches fire, do not attempt to put out the fire and evacuate immediately.
Seek medical in case of inhalation of pungent and toxic fumes.
Keep damaged batteries isolated and call your local fire department. Contact service department for
further support.
Water damage
Risk of electric shock and internal short-circuit. In case of splash or water spillage, when it is safe to do so,
dry the product. If any part of the battery system is submerged, keep away from water.
Do not reuse the submerged battery. Please contact service department for support

3.PACK B installation
3.1 If installing bracket, use a detector to detect whether there is cable or water tube behind the wall
3.2 The pack should be placed on a level ground (0°~3°), parallel to the wall and keep a distance of at
least 20mm. The handle must be used to lift the PACK off the ground for movement.
4.PACK A installation
When stacking battery modules, align one end of the connector first, then slowly drop
the battery connector end until the case fits, and finally drop the other end.
Warning! Do not drop the non-connector end first to avoid damage to the connector!
5. After installing PACK A, fix bracket 2 with a cross screwdriver (torque screwdriver 5 N.M). (The

4.4 Cable making
4.5 Cable connection
4.5.1. Single device cable connection
The wiring of the device is shown in the figure below. For the wiring on the inverter side, please refer to
the inverter user manual.
4.5.2 Cable connection of parallel cabinets
（1）When the devices are connected to the inverter in parallel, the output positive and negative cables of
each device are connected to the combiner box, and then the cables are connected from the combiner
box to the inverter.
（2）Up to 3 parallel connections are supported.
Step1
Strip the communication cable
stripper with Ethernet and guide
the corresponding signal cable
output. Pass the communication
cable through ICX10-F12A1T,
insert the RJ45 plug in the correct
order, and crimp it with a crimper.

6. Maintenance manual/general troubleshooting
6.1 Routine maintenance
The battery needs to be recharged every 6 months if not working
From the date of shipment from the manufacturer, the battery needs to be maintained at a maximum
interval of 6 months; the requirements for the recharge interval after the battery is empty are as follows:
Ambient temperature (45,50]℃, should be recharged within 7 days;
Ambient temperature (35,45]℃, should be recharged within 15 days;
Ambient temperature ≤35℃, should be recharged within 30 days.
When the device is placed unused, the battery SOC should be in the range of 45%~55%, and battery
output should be disconnected to prevent the battery from draining.
During the storage period of the system, professionals should regularly check the system to check
whether the lines are loose or fall off, and clean the surface of the system; if any defects are found,
please contact the dealer in time.
