4. Electrical installation of charger
4.1 General Specification
Before performing any electrical installations, ensure that you have a clear understanding of the following electrical regulations
for the charger:
Wiring terminal definition
Cable requirement
Note: 1. For the DVC10-A7KGP1E charger, the maximum continuous working current is 32A, and the cable must
meet these requirements. We recommend using a 10 AWG cable with a 600Vac withstand voltage rating. However,
you may also opt for a larger cable size.
2. For single-phase AC chargers, the power cable can have a sheath, but its maximum allowable diameter should
not exceed the range shown in the diagram above; otherwise, assembly cannot be completed.
For the charger models DVC10-A11KGP1E and DVC10-A22KGP1E, they are suitable for 360-440Vac three-phase AC power
(TN):

13
Note: 1. For the DVC10-A11KGP1E charger, the maximum continuous working current is 16A, and the cable
should meet the above requirements. It is recommended to use a 12 AWG cable with a 600Vac withstand voltage
rating.
2. For the DVC10-A22KGP1E charger, the maximum continuous working current is 32A, and the cable
should meet the requirements outlined above. We recommend using a 10 AWG cable with a 600Vac withstand
voltage rating. However, you can opt for a larger cable size if desired.
3. For single-phase AC chargers, the power cable can have a sheath, but its maximum allowable diameter
should not exceed the range shown in the diagram above; otherwise, assembly cannot be completed.
4.2 Electrical installation procedure
Since the connection of the cable is made in the rear plate of the charger, the electrical installation work should be completed
before the mechanical installation.
(1) Cable pre-treatment
•Measure the actual length of the AC power cable according to the installation location of the charger, and pretreat the
cable (If possible, crimp the cable to a tubular terminal for subsequent connection) for preparation.
•Remove the rear plate maintenance cover
•Use a screwdriver to remove the maintenance cover screws, revealing the terminal connected to the AC cable and the
power distribution module.
•Please keep the maintenance cover and fixing screws aside for future use.
A: Wiring terminal; B: Maintenance cover plate;
C: Screws; D: Waterproof seal.
Note: Be sure not to discard the related parts when removing the maintenance cover, such as waterproof seals and securing
screws
(2) Pre-install cables
•Loosen the waterproof jacket of the cable by turning it counterclockwise.
•Insert the pre-treated cable into the waterproof jacket, leaving a cable length of approximately 10~15mm based on the
installation position for easy access to the terminal. (Note: Crimping the cable to a tubular terminal is essential for a
secure connection.)
•To secure the waterproof jacket, turn it counterclockwise until it's tightened.

(3) Charger AC input cable connection
•Use a screwdriver to unscrew and loosen the fixing screws on the wiring terminals.
•Attach the cable to the appropriate terminal port, following the installation diagram for guidance. Then, use a
screwdriver to secure the screws to the specified torque level. (Recommended torque: Max 2 Nm. / 10.6 Lbf.in)
•Once the connection is made, gently pull the cable with slight force to ensure it remains securely in place. If the cable
doesn't come loose, the connection is secure.

Note: 1. Engineers can differentiate the wiring by examining the markings on the terminal row in addition to referring to
the pictures provided above for AC input cable connections.
2. Before connecting the AC input cable to the power grid network, please complete the mechanical installation of
the charger first to ensure safety.
(4) Install the rear plate maintenance cover
•Ensure that you remove any debris that may be left inside the charger after installing the AC input cable.

15
•Before installing the maintenance cover, check the waterproof seal strip to ensure it is correctly installed in the groove.
•Reattach the maintenance cover plate and securely fasten the fixing screws with a screwdriver.
Note: Please refrain from removing the waterproof sealing strip during installation. Doing so may compromise the charger's
waterproofing, allowing water to enter and potentially causing short circuits and damage.
5. Mechanical installation of the Charger
5.1 Installation procedure of power distribution module (Optional)
•When this function module is not attached, please disregard this installation procedure and proceed with the subsequent
mechanical installation.
•This installation procedure involves the removal and installation of the maintenance cover plate.
(1) Cable hole pre-treatment
Identify the wire hole for the power distribution module located at the
charger's bottom. Use appropriate tools like screwdrivers to prepare the
wire holes by removing any obstructing material. Then, open the prepared
sealant shell. Carefully insert the wire into the sealant hole and ensure
it is properly secured.
(2) Power distribution module cable connection
Insert the cable through the glue hole, connect the wires to their corresponding interfaces as defined, and then tighten the fixing
screws.
Install the rear cover plate after the above wiring harness connection is completed.
4 PIN terminal wiring definition
General specification for the wiring
Recommended cables: UL2464-4 * 22 AWG or 24 AWG
four-core wire (or other four-core wire)
Recommended length: The recommended cable length is
not more than 40 meters except in exceptional
circumstances.
(3) Power distribution module installation
Install the module on the side of the charger, then insert the current transfer to the power input wire L (L1, L2, L3 for three-
phase).

16
5.2 General Specification
•The engineer or user should supply four expansion bolts measuring M6x50mm, with a load-bearing capacity of at least
10kg.
