SAFETY
SAFETY ANNOUNCEMENTS
Before operating the EV charger, read the instructions and precautions carefully to reduce the risk of accidents.
The “caution, warning, hazard” notices in the product and product manual do not represent all safety concerns
to be observed and are only intended to supplement the various operational safety precautions.
In carrying out the company’s product and equipment operations, you must comply with relevant industry safety
norms and strictly abide by these instructions to provide the appropriate equipment precautions and special
safety instructions

SAFETY
ELECTRICAL SAFETY
HIGH VOLTAGE
Some components of the power system operate with high voltage. Direct or indirect
contact with these components through non-insulated protective material poses a fatal
hazard.
The installation of AC power supply equipment must comply with safety regulations, and personnel carrying out
the installation of AC equipment must be qualied in high voltage AC-power operation.
It is strictly prohibited to wear watches, bracelets, rings or other conductive objects on your wrist or hand.
Turn off the power immediately if you nd water or moisture in the electric cabinet. When operating in humid
conditions, water should be strictly prevented from entering the equipment.
A “Do not operate” sign must be hung on switches and buttons that are not to be used during installation.
Construction of high-voltage lines can cause re or electric shock accidents.
The racking and wiring of AC cables through the area must comply with the local
regulations and specications. Only personnel qualied for high-voltage and AC
operations can carry out various high-voltage operations.
TOOLS
Special tools must be used for all high AC voltage operations.
THUNDERSTORMS
High AC voltage operations during thunderstorms are strictly prohibited.
Strong electromagnetic elds are produced in the atmosphere during thunderstorms. To avoid lightning
damage to equipment and personnel, do not carry out any operations during thunderstorms.
ELECTROSTATICS
Static electricity generated by the human body can damage electrostatic-sensitive
components on boards such as large-scale integrated circuits (ICs). To prevent static
damage to sensitive components, personnel must wear an anti-static bracelet when in
contact with equipment (hand-held boards, circuit boards, IC chips, etc.). The anti-
static bracelet must be well-grounded on the other end.

SAFETY
SHORT CIRCUITS
It is strictly prohibited to short-circuit the power supply system to the positive and
negative poles or to short the non-ground pole to ground during operation. Short
circuits can cause equipment to burn and pose a personal safety hazard.
In addition, the polarity of the cables and interface terminals must be strictly checked when carrying out live
work.
Power distribution operation space is limited. Before any operation, close attention must be paid to the choice
of operating space.
An insulation tool must be used during operation.
When working with electricity, care must be taken to keep your hands, wrists and arms steady, to prevent
accidents from a tool slipping, or from too much movement of a tool or your body.
SHARP CORNERS
When moving equipment by hand, wear protective gloves to prevent cuts.
POWER CABLE
Make sure that the cable label is correct before connecting the cable.
SIGNAL LINE
The signal cable should be tied separately from the power cable and at
least 15mm away.

INSTALLATION
PROCEDURE
SAFETY INSTRUCTIONS
The operating voltage and current inside the charging system are high, and the following regulations should be
observed at all times to ensure personal safety:
1.Chargingsystemsmust only be installedbypersonnel who have beentrainedin,and have sufcient knowledge
of, the charging system. Always follow safety precautions and local safety regulations during installation.
2. To operate inside the charging system, make sure that the charging system is not live. The power input to the
charging system must be disconnected.
3. Distribution cable wiring should be reasonable and protective to avoid accidental contact when operating
power supplies.
VISUAL INSPECTION
Upon product delivery, check that the package is not damaged and that the label is complete and correct. If
there is an issue, immediately inform the carrier and take photos as evidence. At the same time, immediately
contact the manufacturer to discuss the issue.
Only after the goods arrive at the installation site can they be opened and the boxes opened for inspection.
Start by opening the box with the packing slip, taking out the packing list and checking it against each item.
Next, check the serial number of the box, the equipment packaging, the number and type of accessories and
the integrity of all items.
Following the packing list, check that accessories and accompanying documents are complete (refer to the
shipping list) and store the accessories and documents properly.
Carry out a visual inspection to ensure that the product is free of abnormal marks showing collisions, and of
scratches, cracks, dents, rust, breakage, or peeling of paint.
Sign receipt documents, make a record of the situation, keep documents and scan them for archives, or give
them to relevant parties.

INSTALLATION
NETWORK CONNECTIVITY REQUIREMENTS
The recommended way to connect to the network is to access 4G wireless communication. A SIM card meeting
local networking requirements is required. Make sure the local signal strength is strong and stable; otherwise
a signal amplier must be installed.
If there is no local 4G communication signal, a standard wired internet connection is available. Wired
connections must meet the following requirements:
RJ45 Ethernet
Network cable type: 5e class or greater, 8P plus PE, shielding wire.
It is recommended that the line length is less than 75m. Greater than 75m length requires a customised
engineering solution.
Minimum bandwidth required:
Upstream: 128 kbps
Downstream: 4 Mbps
Demand connection reliability: 99.9%.
For special congurations, please contact us.

should be consistent with the phase section.
The section of the ground line must not be less than 16 mm2.
The recommended power distribution input wire diameter of the charger should not be less than the following
recommended values and should have a separate circuit breaker and leakage. Please see table below:
