2 Safety

2.1 Important Safety Instructions

Danger!

Electric shock and high voltage.

● Do not expose the storage unit to temperatures in excess of 45°C.

● Do not subject the storage unit to any strong force.

● Do not touch uninsulated cable termination.

● Do not soak the storage unit in water or expose it to moistur

environment.

● Do not touch the case of the storage unit when it is wet in case of

electric shock.

● Do not dispose of batteries in fire. The batteries may explode!

● Do not place the storage unit near a heat source, such as dire

sunlight, a fireplace.

● Keep inflammable and explosive dang erous items or flames away

from the storage unit.

● Do not charge or discharge damaged storage unit.

Before performing any work on the storage unit, please disconne

the storage unit from all voltage sources as described in this

document.

Warning!

● Installation, repair, recycling, and disposal of storage unit must be

performed by qualified personnel in accordance with national and

local standards and regulations.

● Risks of chemical burn electrolyte or toxic gases.

● Do not place heavy objects on the top of the system.

● Do not connect any un-dedicated battery pack to UHome storage

unit.

● If the moisture penetrates the system (e.g., due to casing

damage), please do not install or operate the system.

Do not use wet hands to touch the system.

● Any behavior to change the functionality of the product without

permission will cause fatal injury to the operator, third parties, and

equipment. UHome is not responsible for these losses and

warranty claims.

● To ensure property and

personal safety, the batteries and inverter

shall be well grounded.

！

Caution!

● Do not modify or tamper with storage unit and other components

the system.

● Risk of injury by hoisting or falling system

● Batteries are heavy and personal injury can be caused if the

battery is improperly lifted or dropped during transport or improper

operation when attached or removed from walls. Lifting and moved

the products shall be conducted by more than one person.

Note

● Do not extend other brands of batteries at the battery port.

2.2 Explanation of Symbols

This section explains all the symbols shown on the inverter and on the type

label.

Dangerous electrical voltage

All work to the battery shall only be carried out by qualified personnel.

No open flames

Do not place or install near flammable or explosive materials.

Corrosive substance

Keep the machine away from corrosive substance.

Attention

Install the product out of reach of children

Danger of hot surface

The components inside the device will release a lot of heat during

operation. Do not touch metal plate housing of the machine during

operating.

Danger.

Risk of electric shock!

An error occurred

Read the usage manual to troubleshoot problems

This device SHALL NOT be disposed of in residential waste

Please go to Chapter Seven “Battery maintenance” for proper

treatment.

Caution

2.3 Emergency situation

Despite of its careful and professional protection design against any hazard

results, damage of the battery may still occur. 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 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.

Potential danger of damaged battery:

Chemical Hazard: Despite of its careful and professional protection design

against any hazard results, rupture of battery shall 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).

Warning!

If a fire has just occurred, try to disconnect the battery circuit breaker an

cut off the power supply first, but only if you can do so without endangeri

yourself.

If the battery is on fire, do not attempt to extinguish the fire and evacuate

the crowd immediately.

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.
