The battery storage system should not be installed in direct sunlight or on flammable
surfaces. Please be sure to mount the battery storage system tightly on a solid /
smooth surface. The optimal temperature range for the battery storage system to
operate is 10 to 30°C . The operating humidity is within the range from 0 to 95%.
If the ambient temperature is outside the operating range, the battery storage
system stops to protect itself from any unexpected damage.
This battery storage system should be installed by a trained and experienced
installer designated by the retailer. Having the product installed by a non-specialized
installer is very dangerous and can cause damage or injury. The battery storage
system is always installed by 2 or more people. (According to regional regulation,
more people may be required.)
Please make sure any breaker is turned off before connecting cables. Be careful
of the cable length must be less than 100 meters.
1.2.3 Safety Instructions
The battery module contains flammable materials such as organic solvents.
Mishandling the battery module may cause fire, smoke, or an explosion and
the battery module’s functionality will be seriously damaged. Protection circuits
are designed into the battery storage system via BMSS (PCB part inside the
battery cabinet) to protect the battery modules.
Please read and check the following prohibited actions.
1.2.3.1 Handling of Prohibitions
8
Safety

(1) Electrical Shock
Do not touch the terminals of the battery module without protectors.
Be grounded with the specified conditions.
High voltage may occur between the positive and the negative terminals.
Electric shock impairs health or may cause threat to life.
More than 2,000 meters higher, risks of an electric shock will be increased.
(2) Immersion
Do not immerse the battery module in liquid such as water, beverages, or
other fluids.
Do not expose to corrosive substances such as sea breeze, steam or chemicals.
Do not install in the humid places or places to condensation.
Exposure to liquid may damage the battery module or the circuit board.
This may cause a battery module's damage to leak electrolyte, generate
heat, smoke, catch fire, or explode.
(3) High Temperature
Do not use or place the battery module near an open flame, heater or high
temperature. Subjecting the battery module to high temperature may damage
the separator and cause internal short circuit.
This may cause the battery module's damage to leak electrolyte, generate heat,
smoke, catch fire, or explode.
(4) Charge Conditions
Only charge the battery module within the specified conditions.
(e.g., temperature range, voltage, current and etc.)
Charging with unspecified conditions (e.g., over charge or abnormal current)
may cause the battery module's damage to leak electrolyte, generate heat,
smoke, catch fire,or explode.
(5) Reverse Polarity
Check the positive (+) and the negative (-) terminals.
If the battery module is connected with a reversed polarity, unexpected
reactions may occur.
This may cause the battery module's damage to leak electrolyte, generate
heat, smoke, catch fire, or explode.
DANGER!
- This warning indicates an immediate hazard which will lead to death or serious
injury may occur.
