⚫For the equipment that needs to be grounded, install the protective earthing (PE) cable
first when installing the equipment and remove the PE cable last when removing the
equipment.
⚫Do not damage the ground conductor.
⚫Do not operate the equipment in the absence of a properly installed ground conductor.

grounded.
General Requirements
———————————————————————————————————————————
DANGER
Before connecting cables, ensure that the equipment is intact. Otherwise, electric shocks
or ire may occur.
———————————————————————————————————————————
⚫Ensure that all electrical connections comply with local electrical standards.
⚫Obtain approval from the local electric utility company before using the equipment in
grid-tied mode.
⚫Ensure that the cables you prepared meet local regulations.
⚫Use dedicated insulated tools when performing high-voltage operations.
DC Operation
———————————————————————————————————————————
DANGER
PhaseGreen

1 Safety Precautions
Version 1.2 Copyright © PHASEGREEN TECHNOLOGY INC 9
Do not connect or disconnect power cables with power-on. Transient contact between
the core of the power cable and the conductor will generate electric arcs or sparks, which
may cause fire or personal injury.
———————————————————————————————————————————
⚫Before connecting cables, switch off the disconnector on the upstream equipment to cut
off the power supply if people may contact energized components.
⚫Before connecting a power cable, check that the label on the power cable is correct.
⚫If the equipment has multiple inputs, disconnect all the inputs before operating the
equipment.
Cabling Requirements
⚫When routing cables, ensure that a distance of at least 30 mm exists between the cables and
heat-generating components or areas. This prevents damage to the insulation layer of the
cables.
⚫Bind cables of the same type together. When routing cables of different types, ensure that they are
at least 30 mm away from each other.
⚫Ensure that the cables used in a grid-tied PV power system are properly connected and insulated
and meet specifications.
⚫The positions where cables are routed through pipes or holes must be protected to prevent the
cables from being damaged by sharp edges or burrs.
⚫When the temperature islow, violent impact or vibration may damage the plastic cable sheathing.
To ensure safety, comply with the following requirements:
–Cables can be laid or installed only when the temperature is higher than 0°C. Handle cables with
caution, especially at a low temperature.
–Cables stored at subzero temperatures must be stored at room temperature for at least 24
hours before theyare laid out.
1.4 Battery Safety
Declaration
The Company shall not be liable for equipment functional abnormality, component damage,
personal safety accident, property loss, or other damage caused by the following reasons:
⚫The batteries are not charged asrequired during storage, resulting in capacity loss or irreversible
damage to the batteries.
⚫A battery is damaged, falls, or leaks due to improper operations or incorrect connection.
⚫After being installed and connected to the system, the batteries are not powered on in time, which
causes damage to the batteries due to over discharge.
⚫Battery running parameters are incorrectly set.
⚫The customer or a third party uses the batteries beyond the scenarios specified by the Company.
For example, connect extraloads, or use with other batteries, including but not limited to batteries
of other brandsor batteries of different rated capacities.
⚫Damage is caused to batteries because the batteryoperating environment orexternal power
parameters do not meet environment requirements. The actual operating temperature of batteries
is too high or too low, or the power grid is unstable and experiences outages frequently.
⚫Batteries are frequently over discharged due to improper maintenance, capacity is incorrectly
expanded, or the batteries have not been fully charged for a long time.
PhaseGreen

1 Safety Precautions
Version 1.2 Copyright © PHASEGREEN TECHNOLOGY INC 10
⚫Batteries are not maintained based on the operation guide, such asfailure to check battery
terminals regularly.
⚫Batteries are stolen.
⚫The warrantyperiod of batteries has expired.
Basic Requirements
———————————————————————————————————————————
DANGER
⚫Do not expose batteries at high temperature environment or around heat-generating sources, such
as sunlight, ire sources, transformers, and heaters. The battery may cause a fire if overheated.
⚫To avoid leakage, overheating, or fire, do not disassemble, alter, or damage batteries. For example,
do not insert foreign objects into batteries or place batteries in water or other liquids.
⚫The fire hazard of the lithium-ion/sodium-ion battery energy storage system is high. Consider the
following safety risks beforehandling batteries:
⚫Battery electrolyte is combustible, toxic, and volatile.
⚫Batterythermal runaway can generate flammable gas and harmful gas such as CO and HF.
———————————————————————————————————————————
⚫The batteries must be stored separately inside the packaging. Do not store batteries together with
other materials or in the open air. Do not stack batteries too high.
⚫Do not use batteries beyond the warranty period.
⚫Do not remove the battery packaging before use. Batteries should be charged during storage by
professionals as required. Put batteries back to their packaging after charge during storage.
⚫Move batteries in the correct direction. Do not place a battery upside down or tilt it.
⚫Protect batteries from impact.
⚫Do not perform welding or grinding work around batteries to prevent fire caused by electric sparks
or arcs.
⚫Use batteries within the temperature range specified in this manual.
⚫Do not use damaged batteries (such as damage caused when a battery is dropped, bumped, or
dented on the enclosure). Damaged batteries may release flammable gases. Do not store damaged
batteries near undamaged products.
⚫Do not place damaged batteries in close proximityto flammable materials. Do not approach the
damaged batteries unless you are a professional.
⚫Monitor damaged batteries during storage for signs of smoke, electrolyte leakage, or heat.
Personal Safety
⚫Wear proper personal protective equipment (PPE) during operation. If there is a probability of
personal injuryor equipment damage, immediately stop the operations, report the case to the
supervisor, and take feasible protective measures.
⚫Use tools correctly to avoid hurting people or damaging the equipment.
⚫Do not touch the energized equipment, as the enclosure is hot.
⚫To ensure personal safety and normal use of the equipment, the equipment must be reliably
grounded before use.
⚫When a battery is faulty, the temperature may exceed the burn threshold of the touchable surface.
Therefore, avoid touching the battery.
PhaseGreen

1 Safety Precautions
Version 1.2 Copyright © PHASEGREEN TECHNOLOGY INC 11
⚫Do not disassemble or damage the battery. The released electrolyte is harmful to your skin and
eyes. Avoid contact with the electrolyte.

attention to the following points:
(a) Remove any metal objects from yourself, such as watches and rings.
(b) Use tools with insulated handles.
(c) Wear rubber gloves and boots.
(d) Do not place tools or metal parts on top of batteries.
(e) Before connecting or disconnecting battery terminals, disconnect the charging power
supply.
(f) Check whether batteries are accidentally grounded. If it is accidentally grounded, remove
the power supply from the ground. Touching any part of a grounded battery can cause an
electric shock. If these grounding points are removed during installation and maintenance, the
possibility of electric shocks can be reduced.
⚫Do not use water to clean electrical components inside or outside of a cabinet.
⚫Do not stand on,lean on, or sit on thetop of the equipment.
⚫Do not damage the modules of the equipment.
Battery Emergency Measures
———————————————————————————————————————————
