3.4. Name Rules
3.5. Product Functions and Features
The AC charging pile is a new product designed according to customer needs. The product has the
characteristics of small size, lightweight, high charging efficiency, small floor space, and stylish
appearance.
The charging pile design has various protections, including AC leakage protection, lightning
protection,over-current alarm, and protection, Over/under voltage protection, and emergency power-off
protection.
The AC charging post has the following features:
◼Safe and stable: The wall-mounted/column AC charging pile provides a reliable electrical safety
protection function. It can be anti-theft, dust-proof, waterproof, and stable in operation, ensuring
reliable long-term operation. Meets the outdoor IP54 protection;
◼System integration: The functions of the entire charging pile, such as charging function, man-machine
operation, safety protection, and function, are highly integrated. The system is simple in structure,
conducive to production, and stable and reliable in operation;
◼Easy to operate: friendly man-machine interface, simple and clear, easy to operate;
◼Small footprint and convenient installation: the area and space occupied by the entire charging pile
are very reasonable, improve space utilization, and facilitate installation and application in areas with
tight land ;
◼Connection abnormality: It can bejudged whetherthe charging connector is properly connected.When
properly connected, the charging interface can output power. When the charging connector is
abnormally disconnected, theAC charging poststops outputting immediatelyto ensure personal safety
and charging safety;
◼Multiple protection: The charging pile has the functions of output over-voltage, under-voltage and
overload protection. When the charging voltage exceeds the overvoltage protection setting or is lower
than the under-voltage protection setting, the charging post stops charging to protect the charging
device. When the charging current exceeds the fixed value of the load current, the delay 5S sends an
alarm signal and automatically cuts off the charging power;
◼Charging pile has short circuit and leakage protection function;

Charging pile input incoming line connection:
The device must be grounded. The firewire (L) neutral wire (N) must be tested with the test pencil. The
electric pen test is lit by the firewire (L), and then the L wire and the N wire are respectively connected to
the corresponding terminals!
Safety Warning: In order to ensure safe charging, the user must strictly follow the phase sequence of the
incoming terminal when wiring the input. At the same time, the charging pile with a rated current of 32A,
the incoming input line is not less than 6 square copper core wire; the charging pile with the rated current
is 16A, the incoming input line is not less than 4 square copper core wire. (After wiring is completed, put
it back into the lead wire of the column or protect it with a protective cover to prevent accidental exposure.)
The following safety regulations are observed when charging and wiring the charging pile:
