system.
This user manual provides important instructions for DELTA BX6.3_AC Battery
storage system.
The product is designed, tested, verified, and certified according
to international
safety requirements, regulations, and standards but precautions
must be observed
when installing and operating the product.
The DELTA BX6.3_AC is a battery storage system designed with two battery
modules. In order to prolong Lithium-based batteries' life, 100% state of charge
(SOC) shown on the device is actually within the range of 95%~100%.
The battery storage system can be charged/discharged from grid, and provides
electricity to household loads and electricity supply backup is available.
The DELTA BX6.3_AC Battery storage system is NOT to be used as a backup
for any medical uses or life supporting uses.
Before battery module running one cycle, there might be some error in the SOC
accuracy.
If DELTA BX6.3_AC has not used for more than six months, please connect to grid
and check the SOC value via APP, if the SOC value is below 30%, please select
“Charge first mode” to charge BX6.3_AC, it should be charged to at least 30% SOC.
Utilize a brand new battery with used one may lead to reduction of battery lifetime
and increase the safety risk. Therefore, we suggest the evaluation of the battery
size have to be made thoroughly before installation.
Extend the battery size from 6.3kwh to 12.6kwh is not allowed.

The battery storage system should not be installed under direct sunlight or
on flammable surfaces. Please make sure the battery storage system is mounted
tightly on a solid / smooth surface. The optimal temperature range for the battery
storage system to operate is 10 to 30℃. The operating humidity is within the range
from 0 to 90%. 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 all the breakers are turned off before connecting cables.
Please note that the cable length must within 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
9
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.
10
Safety

(6) Direct Connection
