to directly dispose of the battery, please wear insulating rubber gloves;
(2)Keep away from children;
(3)Before touching the battery, please avoid touching exposed metal parts;
(4)To prevent static electricity from accumulating, maintenance personnel should discharge
static electricity from the human body before operating the battery;
(5)Never put tools or metal parts on top of the battery;
(6)During the assembly process, please be careful not to touch the positive and negative
terminals of the battery with your hands or other metal objects at the same time to avoid
electric shock or short circuit;
(7)Do not step on or sit on the battery;
(8)Do not short-circuit the positive and negative electrodes of the battery directly, otherwise it
Worldwide Energy and Manufacturing USA Co., Limited
5
will cause the battery to leak, heat up and rupture;
(9)It is strictly prohibited to modify the battery without authorization. To prevent danger, a
protection system is installed in the battery. If the protection system is damaged, charging
and discharging may not be controlled, or the charging and discharging current may exceed
the set boundary value, resulting in battery leakage, heat generation and rupture;
(10)It is strictly forbidden to cover the battery during charging and discharging. Otherwise, the
generated heat will accumulate, the battery performance will decrease, and liquid leakage will
occur.
3.1.3 Responding to Emergencies
Electrolyte leakage
If electrolyte leakage occurs, avoid contact with the leaking liquid or gas. If the user is
exposed to the leaked material, please immediately follow the instructions below:
Inhalation: Evacuate the contaminated area and seek medical attention immediately;
Eye contact: Flush eyes with running water for 15 minutes, and seek medical attention
immediately;
Skin contact: Wash the affected area thoroughly with soap and water, and seek medical
attention immediately;
Ingestion: Cause vomiting and seek medical attention immediately.
(2)The battery catches fire
If the battery catches fire, move it to a safe area before the battery catches fire. When the
battery is heated to above 150°C, it may explode; when the battery pack is burned, toxic gas
will be leaked, please do not approach it.
(3)The battery is immersed in water
If the battery is immersed in water, please do not use it before maintenance and inspection by
professionals.
(4)The battery is damaged
A damaged battery may leak electrolyte or produce flammable gas. Damaged batteries are
dangerous and must be handled by professionals.

Step 1: Connect the circuit breaker to the battery box
Two 2P circuit breakers are installed on the cabinet, and each battery box is connected to one
circuit breaker, that is, one circuit breaker controls one battery box. The wiring sequence on
the circuit breaker is "-, +, -, +" from left to right. The circuit breaker on the left controls the
bottom battery box, and the circuit breaker on the right controls the upper battery box.

Step 2: Install the power output wiring harness
The cables from the circuit breaker to the output terminal block have been pre-installed inside
the cabinet. The user only needs to install the output wiring block to the external cables of the
cabinet. Use M6*12 bolts to fix the cables out of the electrical cabinet through the waterproof
connector from the terminal block.
Figure 11. install the power output wiring harness
Step 3: Install the communication harness
Connect the "Link Port 0" of the lower battery box and the "Link Port 1" of the upper battery
box with a network cable. The “CAN” of the upper battery box is connected to the inverter
external to the box.
