connecting the phase and neutral wiring to avoid hazardous voltage.
1) An insulated grounding conductor that is identical in size, insulation material, and thickness to the grounded and
ungrounded branch-circuit supply conductors except that it is green with or without one or more yellow stripes is to
be installed as part of the branch circuit that supplies the unit or system.
2) The grounding conductor described in item 1 is to be grounded to earth at the service equipment or, when supplied
by a separately derived system, at the supply transformer.
480V Three-Phase
WARNING!
The following diagram illustrates DC City Charger connection to L1, L2, L3, and neutral in a Wye power grid feed.
Before Installation

air vent of the product.
● Recommend to keep not less than 100cm (3 ft. 6 in.) clearance distance from all around the product following
NEC table 110.26 condition 2, 151-600V.
NOTICE
It is recommended to conduct Wi-Fi and 3G/4G signal strength while charger installation. The RSSI (Received Signal
Strength Indication) value is considered as good as higher than -65dBm. Poor connection quality might interrupt charging
process or data transaction.
Installing the DC Charger
Preparation
1. Take the key from the handle of the charging connector.
2. Open the left door (clockwise) and right door (anticlockwise).
Press the handle back to the lock slot to make sure that the door lock is closed.
3. Release the 4 screws on the base panel (two sides) with a Torx® Tamper-Resistant T15 & T20 screwdriver. Take out
the base panel.
4. Release the screws on the cabinet and pallet with a No. 19 socket wrench.
5. Transport the cabinet.
Transporting with the crane: The included angle hanging the cabinet on the top shall be 30°.
6. Replace the eye bolts with M12 bolts x4 with a No. 19 socket wrench after the DC charger has been well-placed.
Ground mounting
The EV Charger shall be installed on the ground. During installation, it must be securely and reliably fixed. It is
recommended that the foundation be constructed in accordance with the following foundation drawing:
Making the Connection
Power Wiring
● The electrical installation of the DC charger must be carried out under the guidance of professional technical
personnel. Open the front door of the charging pile and connect the incoming power cable to the upper terminals
of the circuit breaker. Connect the grounding wire to the grounding bolt.
● The charger input uses a three- phase four- wire AC power supply, and the AC incoming current is approximately
235A.
● It is recommended to select copper core cables that meet US standards. Use wire terminals matching the cable
cross- section for crimping. The exposed parts of the terminal connections must be insulated with heat- shrinkable
sleeves or insulating tape. The wiring is shown in the following diagram:
● The AC incoming cable enters the charger from the bottom and is connected to the AC input terminals and the ground
terminal inside the charger. The AC input must be wired in accordance with the incoming line markings. The upstream
circuit breaker and distribution cabinet for the charger must be selected and operated by professional electrical
personnel.
Power- On Preparation
1. Personnel Requirements
Users must complete operation training before using the charger. During operation, they must wear appropriate work
clothes and insulated shoes. Individuals with long hair must wear safety helmets.
2. Pre- Use Inspection
In accordance with electrical operation standards, check the interior of the cabinet for any electrical damage or
displacement. Ensure all terminals are securely crimped and free of damage or burning.
Open the front cabinet door, set the circuit breaker to the ON position, and close the control circuit air switch to
perform a continuity test and ensure there is no short circuit.
Set the circuit breaker to the OFF position to disconnect it. Turn off the control circuit air switch and connect the
AC input power cable.
After applying AC input power, first confirm that the emergency stop button is in the released position. Then turn
on the circuit breaker and air switch, and use a multimeter to verify that power has been applied.
Before charging, inspect the charging gun, the insulators of the charging socket, the pins, and the jacks for any foreign
objects. If any foreign objects are found, please clean them.
Ethernet Connection
1. It is recommended to connect Ethernet cables through the underside access ports. It is necessary to open the front
cover and the left door.
2. Make sure that the cable passes through the grommet and reaches the Ethernet terminal on the upper controller, as
shown in the following figure.
3. Connect the Ethernet cable to the Ethernet terminal.
4. Fasten the cable on the brackets with cable ties.
Cellular Connection
1. Open the door.
2. Insert mirco SIM card onto the micro SIM interface on the upper controller.
Note:
Insert a valid SIM card as detailed above to start cellular connection. Consult with local operator to activate data
service on the SIM card beforehand. Disable PIN check on the SIM card before inserting the card into the modem. Request
APN information from the operator and make sure APN is configured correctly via the configuration tool.
Switch on DC Charger
1. Open the door of City Charger, AC input breaker QF2, QF3, QF4 are marked on the side panel. Follow the steps
to turn on City Charger: QF3 — QF4 — QF2.
2. Switch the power on to initialize DC Charger.
3. DC Charger is ready to charge.
4. To switch off City Charger, open the left door of City Charger, AC input breaker QF2, QF3, QF4 are marked on
the side panel. Follow the steps to turn on City Charger: QF2 — QF4 — QF3.

Maintenance
Annual Requirements
1. Replace the ventilation filter.
2. Conduct a visual inspection of the charging cable and ensure that the cable does not show any
visual damage or deformation.
3. Conduct a visual inspection of the charging connector and ensure that the connector does
not show any visual damage, arcing or rust.
WARNING!
To avoid danger of electrical shock or injury, turn off power at the panel board or load center
before working on the equipment or removing any component. Do not remove circuit
protective devices or any other component until the power is turned off.
Disconnect electrical power to DC City Charger before any maintenance work to ensure that
it is separated from the supply of AC mains. Failure to do so may cause physical injury or
damage to the electrical system and charging unit.
Note:
Even when the key switch is turned off, the circuit before the main terminal is still
hazardous. Please only operate visual inspection at this moment.
Maintenance of the DC City Charger shall be conducted only by a qualified technician.
After opening the front door, turn off the main breaker and auxiliary breaker before any
maintenance work.
