by qualified personnel.

No open flames

Do not place or install near flammable or explosive materials.

Danger of hot surface

The components inside the battery will release a lot of heat during operation. Do not touch metal

plate housing during operating.

Attention

Install the product out of reach of children

An error has occurred

Please go to Chapter 7 “Troubleshooting”to remedy the error.

Equipment with the CE mark fulfills the basic requirements of the Guideline Governing Low-

Voltage and Electro-magnetic Compatibility.

Recyclable

2.3 Battery Handling

Operate and use the battery properly according to user manual, any attempt to modify battery without the permission from SAJ will void the limit

warranty for the battery.

•The battery must be installed at a suitable location with sufficient ventilation

•Do not use the battery if it is defective, damaged or broken.

•Only use the battery with compatible inverter.

•Do not use the battery with other type of battery.

•Make sure the battery is grounded prior to use.

•Do not pull out any cables or open the battery enclosure when the battery is powered on.

•Only use the battery as intended and designed.

2.4 Emergency Situation

Despite of its careful and professional protection design against any hazards, damage of the battery may still possible. If a small amount of battery

electrolyte is released due to a serious damage of the outer casing; or if the battery explodes due to not being treated timely after a fire breaks

out nearby, and leaks out poisonous gases such as carbon monoxide, carbon dioxide and etc., the following actions are recommended:

1）Eye contact: Rinse eyes with a large amount of running water and seek medical advice

2）Contact with skin: Wash the contacted area with soap thoroughly and seek medical advice

3）Inhalation: If you feel discomfort, dizziness or vomiting, seek medical advice immediately.

4）Use a FM-200 or Carbon Dioxide (CO2) fire extinguishers to extinguish the fire if there is a fire in the area where the battery pack is

installed. Wear a gas mask and avoid inhaling toxic gases and harmful substances produced by the fire.

5）Use an ABC fire extinguisher, if the fire is not caused by battery and not spread to it yet.

WARNING

B2 Series Battery

·If a fire has just occurred, try to disconnect the battery circuit breaker and cut off the power supply first, but only if you

can do so without endangering yourself.

·If the battery is on fire, do not attempt to extinguish the fire but evacuate the crowd immediately.

Potential danger of damaged battery:

Chemical Hazard: Despite of its careful and professional protection design against any hazard results, rupture of battery may still occur due

to mechanical damage, internal pressure etc., and may result in a leakage of battery electrolyte. The electrolyte is corrosive and flammable. When

there is fire, the toxic gases produced will cause skin and eyes irritation, and discomfort after inhalation. Therefore:

1) Do not open damaged batteries;

2) Do not damage the battery again (shock, fall, trample, etc.);

3) Keep damaged batteries away from water (except to prevent an energy storage system from catching fire);

4) Do not expose the damaged battery to the sun to prevent internal heating of the battery.

Electrical hazard: The reason of fire and explosion accidents in lithium batteries is battery explosion. Here are the main factors of battery

explosion:

1) Short circuit of battery. Short circuit will generate high heat inside battery, resulting in partial electrolyte gasification, which will stretch

the battery shell. The temperature reaching ignition point of internal material will lead to explosive combustion.

2) Overcharge of battery. Overcharge of battery may precipitate lithium metal. If the shell is broken, it will come into direct contact with the

air, resulting in combustion. The electrolyte will be ignited at the same time, resulting in strong flame, rapid expansion of gas and explosion.
