Overview

System Overview

The WLEVDC-FG01 series is a newly developed DC charging system that builds on years of research, development and field operating experience to meet the demanding reliability, performance and energy-saving requirements of EV DC charging. The rectifier cabinet and the charging dispensers are installed separately: one cabinet serves several dispensers, and power is dispatched flexibly to each parking bay.

StructureCABCABINET + TERMINAL

Separate cabinet and dispensers

SEPARATED ARCHITECTURE

Rectification and heat dissipation are centralised in the cabinet while dispensers stand next to the bays, shortening DC cable runs and saving space. Station expansion only requires additional dispensers.

Safety

General Safety Precautions

To protect people and equipment, follow all safety notices on the equipment and in the user manual during installation, operation, testing and maintenance. The "Notice", "Warning" and "Danger" items in the manual are reminders and supplements, not the complete list of safety rules to be observed.

Personnel

PERSONNEL REQUIREMENTS
Work only after strict training Know the safety notices Master correct operating procedures Part replacement by the manufacturer or authorised staff only Report abnormalities to the project manager promptly

Grounding

GROUNDING REQUIREMENTS
Ground first when installing Remove the ground connection last Never damage the grounding conductor Never operate without grounding Permanent grounding · re-check before operation

Personal safety

PERSONAL SAFETY
Insulated high-voltage safety shoes Anti-static gloves No conductive jewellery Evacuate immediately in case of fire Never return to a burning area

Equipment safety

EQUIPMENT SAFETY
Securely fixed to the base Do not touch internal parts while running Screws tightened / latches secured Clear packaging material after installation

Electrical safety

ELECTRICAL SAFETY
Never connect or disconnect power cables live Switch off the input side first Verify power cable connections Ground first where high leakage current is marked Do not enter flammable or explosive areas

Mechanical safety

MECHANICAL SAFETY
Wear protective gloves Forklift handling recommended Avoid hand injuries

Cable laying

CABLE LAYING
Bind signal and power cables separately Avoid severe impact and vibration Handle with care in low temperatures Never push the unit off a vehicle

Fire sealing

FIRE SEALING
Seal all cable entry and exit holes Fire putty thicker than 20 mm Approx. 1–2 kg per hole Poor sealing causes condensation
DANGER Danger

Never install or remove power cables while energised. An arc or spark may occur the moment the conductor touches, causing fire or eye injury. Always switch off the input (or upstream) power before installation or removal.

CAUTION Notice

Wear protective gloves when handling the unit by hand to avoid cuts; a forklift or other mechanical aid is recommended. Signal cables must be bound separately from power or high-voltage cables, and severe impact or vibration must be avoided during laying.

REQUIREMENT Fire sealing requirements

After installation, all cable entry and exit openings must be sealed with fire putty at least 20 mm thick. Unsealed or poorly sealed openings cause condensation that shortens the service life of components and busbars.

AC input wiring requirements

AC INPUT
Starting pointRun the AC input cable from the user's distribution switch and connect it to the switch output terminals only when power-on is imminent. The distribution point must provide over-current, short-circuit and lightning protection, with a switch capacity of at least 1.3–2 times the actual load.
Visual inspectionCables must be free of broken strands, damage and scoring.
Cable entry and phase sequenceAC cables enter from the bottom of the unit after removing the bottom entry plate; L1, L2, L3 and N correspond to breakers A, B, C and N inside the cabinet, and PE connects to the internal grounding bar.
SealingAfter wiring, seal all cable entry openings with fire putty, about 1–2 kg per hole.

DC wiring requirements

DC CONNECTION
Power cable routingFrom the DC output busbar of the cabinet to the DC input busbar of the dispenser: two groups (DC+, DC-) plus grounding for dual-gun dispensers, one group plus grounding for single-gun dispensers, using 4+1 core cable with main conductors paralleled in pairs.
Visual inspectionCables must be free of broken strands, damage and scoring.
Auxiliary cable loopingThe 220 V supply and communication cables leave the host terminal block and run to dispenser 1, then from dispenser 1 to dispenser 2, and so on to the last dispenser.
SealingAfter wiring, seal all cable exit openings with fire putty, about 1–2 kg per hole.

Commissioning and maintenance

Commissioning & Maintenance

Inform our technical staff before testing; system commissioning must be carried out by trained personnel. Before power-on, complete the installation safety check and confirm that the AC input switch is open, the equipment is reliably grounded and all internal wiring and screws are tight.

Pile Power-on Commissioning

Inform our technical staff before testing; commissioning must be carried out by trained personnel. Remove rings, watches and other metal objects that may cause short circuits. Beware of high voltage and ensure good grounding before power-on.

Pre-power-on checklist

Pre-power-on Checks

Complete the following four steps in order: confirm cabinet grounding and internal tightness, then measure insulation and three-phase voltage, and finally close the secondary-circuit leakage breaker and the AC input switch.

Tightness checkCheck that the cabinet is reliably grounded and that internal wiring and screws are tight.
Insulation and gridOpen all breakers in the AC distribution cabinet and measure insulation resistance between phases and to earth with a megohmmeter. After mains supply is applied, measure the three phase voltages with a multimeter to confirm the grid is normal.
Secondary circuit power-upClose the miniature leakage breaker of the secondary circuit; monitoring starts, the screen enters standby and the status indicator lights up.
AC input closingClose the AC input switch; the system powers up and enters standby, after which the first charging session can start.
