1.1 Safety Notes
1.1.1 Personal security
Hazard
No energized operation is allowed during the installation
process. Avoid installing and removing cables with power, the
moment the core of the cable touches the conductor, it will
generate electric arc, electric spark or fire and explosion, which
can lead to fire or personal injury.
When equipment is energized, unregulated and incorrect
operation may produce fire, electric shock, or explosion, resulting
in injury, death, or property damage.
No watch, bracelet, bangles, rings, necklaces and other
conductive objects shall be worn during operation to avoid being
burned by electric shock.

User Manual
3
Specific insulated tools are required during operation to
avoid electric shock or short-circuit faults, and the voltage
withstand level of the insulated tools must meet the requirements
of local laws, regulations, standards, and specifications.
Warning
Dedicated protective equipment, such as protective clothing,
insulated shoes, goggles, helmets, insulated gloves, etc., must
be used during the operation.
1.1.2 Electrical security
Hazard
Before carrying out electric connections, make sure that the
equipment is undamaged, otherwise it may cause electric shock
or fire.
Unregulated or incorrect operation may cause accidents
such as fire or electric shock.
Prevent foreign objects from entering the equipment during
operation, as this may result in short-circuit failure or damage to
the equipment, dropping of power supply to the load or power
loss, and personal injury.
Warning
When installing equipment with grounding requirements, the
protective ground wire should be installed first; and when
removing it, the protective ground wire should be removed last.
1.1.3 Environmental security
Hazard
Do not place the equipment in an environment of flammable,
explosive, corrosive gases or fumes, prohibit any operation in

User Manual
4
such environment.
Do not store flammable or explosive materials around the
equipment.
Do not placethe equipment nearsources of heat or fire, such
as fireworks, candles, heaters or other heat generating devices,
as heat exposure to the equipment may result in damage to the
equipment or cause a fire.
Use special insulated tools during operation to avoid electric
shock injury or short circuit failure, and the voltage withstand
level of insulation must meet the requirements of local laws,
regulations, standards or specifications.
Warning
Install the equipment in an area away from liquids, avoid
installing it under water pipes, air outlets and other locations that
are prone to condensation; and avoid installing it under air
conditioning outlets, vents, server room outlet windows and other
locations that are prone to water leakage, in order to prevent
liquids from entering into the interior of the equipment and
causing equipment malfunctions or short-circuits.
Do not use objects to cover the equipment, block vents, or
heat dissipation systems while the equipment is in operation to
prevent heat damage to the equipment or fire.
1.1.4 Machinery security
Hazard
Wear a helmet, safety belt and safety rope when working at
height, and fasten them to a firm and sturdy structure; do not
hang them from moving objects that are not firm or metal with
sharp edges to prevent hooks slipping off and falling accidents.
Warning
Tools need to be prepared and qualified by professional
organizations, avoiding the use of tools with scars, unqualified

User Manual

tests or beyond the validity period of the test to ensure the
firmness of the tools, and not exceeding the load.
Before installing the equipment into the cabinet, first make
sure that the cabinet has been fixed well to avoid the cabinet
being tilted and collapsed due to the unstable center of gravity,
resulting in the installer being smashed and the equipment being
broken and other problems.
When pulling equipment out of the cabinet, be careful of
unstable or heavy equipment that may be installed in the cabinet
to avoid being crushed or smashed.
Do not drill holes in the equipment. Drilling holes can
damage the sealing, electromagnetic shielding performance,
internal components and cables integrity of the equipment, and
metal shavings from drilling holes into the equipment can lead to
a short circuit of the circuit board.
1.1.5 Battery Security
Hazard
Do not shield other loads to connect the positive and
negative terminals of the battery directly, otherwise a short circuit
will be caused. Battery short-circuit will instantly generate a large
current and release considerable energy, causing battery
leakage, smoke, flammable gas release, thermal runaway, fire or
explosion. In order to avoid the short-circuit, do not maintain the
battery with electricity.
Do not expose the battery to high temperatures or place it
around heat generating devices, such as high temperature
sunlight, ignition sources, power transformer, heater and so on.
Overheating of the battery may cause leakage, smoke, release
of flammable gases, thermal runaway, fire or explosion.
Avoid mechanically shocking, dropping, bumping,
puncturing with hard objects and pressure shock to the battery,

which may result in battery damage or fire.
Do not dismantle, modify or damage the battery (e.g.
inserting strange objects, extruding with external force,
immersing in water or other liquids), which may cause battery
leakage, smoke, release of combustible gases, thermal runaway,
fire or explosion.
Do not touch the battery terminals with other metal objects,
it may cause heat generation or electrolyte leakage.
Warning
Battery installation and testing shall be equipped with fire
protection facilities, such as fire sand, carbon dioxide fire
extinguishers, etc., in accordance with construction standards
and specifications. Before putting into operation, make sure that
the fire fighting facilities are equipped in accordance with local
laws, regulations and specifications.
Installation of the battery should be in an area away from
liquids, never place it below air conditioning outlets, vents,
machine room outlet windows, water pipes and other locations
prone to water leakage, in order to prevent liquids entering the
interior of the equipment to cause equipment malfunction or
short-circuit.
Charge the battery in time after it is discharged, otherwise
the battery may be damaged due to over-discharge.

3 Installation Guidance
3.1 Cautionary notes
The product must be installed by a professional in accordance
with local standards and regulations and in strict obedience to the
manual installation procedures. Before starting the installation,
please pay attention to the following:
Whether the ambient temperature is within the designated
range at the installation site: charging at 0~50℃, discharging
at -20~55℃.
The battery system needs to be installed on a flat and
sufficiently load-bearing indoor floor; if the floor has limited
flatness and load-bearing performance, it can be filled by
means of making a foundation and adding load-bearing
plates.
Avoid installing equipment in environments that are close to

User Manual
15
high-temperature heat sources or low-temperature cold
sources.
Avoid installing equipment in areas with excessive ambient
temperature changes or extreme climates.
Avoid installing the equipment in a strong interference
environment.
Avoid installing equipment in areas where children
commonly congregate to prevent access by children.
Avoid installing equipment in areas prone to waterlogging.
Avoid placing flammable, explosive, or corrosive types of
items around the equipment.
Make sure there is a carbon dioxide, Novac 1230 or FM-200
fire extinguisher near the equipment. Use the recommended
type of fire extinguisher. Water or ABC dry powder
extinguishers should not be used to extinguish fires;
firefighters must wear protective clothing and self-contained
breathing apparatus before operating.
The installation location should be well ventilated and avoid
installing or operating the equipment in a smoky environment.
Before installation, the battery system needs to be carried to
the installation site. To prevent injury to personnel or damage
to the equipment during the process, please note the
following：
（1）Estimate the number of hands and lifting tools required
according to the weight of the equipment to avoid damage to the
equipment beyond the range of individually liftable weights.
（2）Ensure that the equipment is balanced during handling to
avoid drops.
Avoid installing equipment in extreme environments such as
sun, rain and snow cover.
Do not tilt or lay the product on its side.
