1.1 Safety precaution
1.1.1 Personal safety
Dangerous
Live operation is strictly prohibited during the installation process. It is prohibited to install
or remove cables with electricity. When the cable core comes into contact with the
conductor, it may generate electric arcs, sparks, or explosions, which can lead to fire or
personal injury.
When the equipment is electrified, the non-standard and incorrect operation may cause fire,
electric shock, or explosion, leading to personal injury or property damage.

User Manual

1.1.2 Electrical safety
Dangerous
Before making electrical connections, please ensure that the equipment is not damaged;
otherwise, it may cause an electric shock or fire.
Unstandardized and incorrect operations may cause accidents such as fires or electric
shocks.
During the operation, it is necessary to prevent foreign objects from entering the interior of
the equipment; otherwise, it may cause short circuit faults or damage to the equipment, load
power reduction or power loss, and personal injury.
Warning
When installing equipment that needs to be grounded, a protective ground wire must be
installed first; When dismantling equipment, the protective ground wire must be removed
last.
1.1.3 Environmental safety
Dangerous
It is strictly prohibited to place the equipment in a flammable, explosive gas, or smoke
environment, and any operation is prohibited in this environment.
It is strictly prohibited to store flammable and explosive materials in the equipment area.
It is strictly prohibited to place the equipment near a heat source or fire source, such as smoke,
fire, a candle, a space heater, or other heating equipment. Heating of the equipment may cause
equipment damage or fire.
During operation, special insulation tools must be used to avoid electric shock injuries or short
circuit faults. The insulation’s ability to withstand voltage levels must meet the requirements of
local laws, regulations, standards, and specifications.
Warning
The equipment should be installed in an area far away from liquids, and it is strictly
prohibited to install it below water pipes, air vents, and other locations that are prone to
condensation; It is also strictly prohibited to install it below the air conditioning outlet,
ventilation outlet, machine room outlet window, and other locations that are prone to water
It is strictly prohibited to wear easily conductive objects such as watches, bracelets, bangles,
rings, necklaces, etc. during the operation to avoid being burned by electric shock.
During operation, special insulation tools must be used to avoid electric shock injuries or
short circuit faults. The insulation’s ability to withstand voltage levels must meet the
requirements of local laws, regulations, standards, and specifications.
Warning
Special protective equipment must be used during the operation process, such as wearing
protective clothing, insulated shoes, goggles, safety helmets, insulated gloves, etc.

leakage, to prevent liquid from entering the equipment and causing equipment malfunction
or short circuit.
When the equipment is running, do not block the ventilation openings, heat dissipation
systems, or use other items to cover it to prevent high temperature damage to the equipment
or ignition.
1.1.4 Mechanical safety
Dangerous
High-altitude operations must wear safety helmets, safety belts, or waist ropes tied to sturdy
structural components. It is strictly prohibited to hang on moving unstable objects or metal
with sharp edges to prevent hook slipping and falling accidents.
Warning
The tools must be fullyprepared and inspected by a professional organization tobe qualified.
It is prohibited to use tools that have scars, fail the inspection, or exceed the inspection
validity period, to ensure that the tools are firm and not overloaded.
Before installing the equipment into the cabinet, first make sure that the cabinet is fixed to
avoid tilting and collapsing due to an unstable center of gravity, which may cause injuries
to installation personnel and equipment damage.
When pulling equipment out of the cabinet, be careful to install equipment that may be
unstable or heavy inside the cabinet to avoid being crushed or crushed.
It is strictly prohibited to drill holes in the equipment. Drilling holes can damage the sealing,
electromagnetic shielding performance, internal components, and cables of the equipment,
and the metal chips generated by drilling holes entering the equipment can cause circuit
board short circuits.
1.1.5 Battery safety
Dangerous
It is strictly prohibited to short-circuit the positive and negative terminals of the battery;
otherwise, it may cause a short circuit in the battery. The short circuit of the battery will
generate a large current and release a large amount of energy in an instant, causing the
battery to leak liquid, smoke, release combustible gas, thermal runaway, fire, or explosion.
To avoid short circuits in the battery, live maintenance is not allowed.
Do not expose the battery to high-temperature environments or around heating equipment,
such as high-temperature sunlight, a fire source, a transformer, a space heater, etc.
Overheating of the battery may cause leakage, smoke, the release of combustible gas,
thermal runaway, fire, or explosion.
It is strictly prohibited for the battery to be subjected to mechanical vibrations, falls,
collisions, hard objects piercing, and pressure impacts; otherwise, it may cause battery
damage or fire.

It is strictly prohibited to disassemble, modify, or damage the battery (such as by inserting
foreign objects, squeezing by external force, immersion in water or other liquids), so as to
avoid liquid leakage, smoke, release of combustible gas, thermal runaway, fire, or explosion
of the battery.
It is strictly prohibited for battery terminals to come into contact with other metal objects,
as it may cause heating or electrolyte leakage.
Warning
When installing and testing batteries, fire protection facilities such as fire sand and carbon
dioxide fire extinguishers must be equipped in accordance with construction standards and
specifications. Before putting into operation, it is necessary to ensure that fire-fighting
facilities that comply with local laws, regulations, and regulatory requirements are in place.
The battery should be installed in an area far away from liquids, and it is strictly prohibited
to install it below areas prone to water leakage such as air conditioning outlets, ventilation
vents, machine room outlet windows, and water pipes, to prevent liquid from entering the
equipment and causing equipment malfunction or short circuit.
After the battery is discharged, it should be charged in a timely manner; otherwise, it may
cause damage to the battery due to over-discharge.
