Application cases
Function description
Charging process of controller with cable type (only CP signal is needed) After switching on the working voltage, the module starts to initialize and perform the function self test (LED light flashes circularly), waiting for the car to connect. The controller waits for the charging cable to connect to the vehicle (status a), and the LED flashes blue continuously. If the cable matching with the controller has been connected (state B), the LED turns to stable blue light and turns on the electromagnetic lock switch. After the gun head interlock, if the vehicle is in State C, the controller will make P1/ P2 in closed state (connected state), and the LED will turn to stable green light. If status D (ventilation required) is displayed, because the controller has no heat dissipation function, the controller makes P1 / P2 in the open state (off state) and turns off the electromagnetic lock switch at the same time, the gun head interlock will be invalid, and the controller will turn off the charging procedure, and the LED will turn into a stable red light
Function description
Charging process of controller without cable type(socket type)(connecting CP
and CS signals)
Before the power is turned on, the CS signal port of the controller can not be
connected to any device ,after the working voltage is turned on, the module
starts to initialize and perform function self-test (LED lights flash
circularly), waiting for the connection of the car cable, this lights flash
circularly), waiting for the connection of the car cable, this process takes
about 10 s.e. The controller waits for the charging cable to connect to the
vehicle (status A), and the LED flashes blue continuously. If the cable
matching with the controller has been connected (state B), the LED turns to
stable blue light and turns on the electromagnetic lock switch(if have). After
the gun head interlock(if have), if the vehicle is in State C, the controller
will make P1 / P2 in closed state (connected state), and the LED will turn to
stable green light. If status D (ventilation required) is displayed, because
the controller has no heat dissipation function, the controller makes P1 / P2
in the open state (off state) and turns off the electromagnetic lock switch(if
have) at the same time, the gun head interlock will be invalid, and the
controller will turn off the charging procedure, and the LED will turn into a
stable red light. In E and f States, the LED will not be on again when the
electromagnetic lock switch is off and the controller turns off the charging
procedure.
In the fault state, the controller turns P1 / P2 on (off) and turns off the
electromagnetic lock switch. The LED turns red and flashes continuously.
Ventilation requirements
In the absence of ventilation, the risk of asphyxiation may be caused due to
the accumulation of some battery related gases when charging indoor. If the
charging process is carried out indoor, forced ventilation shall be installed,
the charging pile controller does not have forced ventilation function.
Connection confirmation line (CS) current, resistance correspondence
information. current resistance/ current resistance/ current resistance /
current resistance/ current resistance 32A 732Ω / 25A 536Ω / 20A 432Ω / 16A
348Ω / 10A 249Ω When the input resistance (minimum) is lower than 100Ω, it
cannot be charged or interlocked. The controller will reduce the current load
to 7a within 5S, and the controller will enter Status A until the resistance
value of the input current rises.

Installation
Installing to DIN rail
- Install the controller (a) vertically on the horizontal DIN rail (b).
- Rotate the device down until the slider on the DIN rail snaps in.
(Note: DIN rail: rail in accordance with German industrial standards)
Wiring
Warning: improper (connection) fuses can cause heat or fire.
The internal self-reset fuse is designed only for the protecting device
itself, and it is the responsibility of the controller’ S user or factory
operator to protect the circuit related to the control. This device does not
include the contactor of load output. Improper use of the contactor of load
output will cause heat or fire when the line is overloaded. The contactor of
load output is installed from outside by the factory operator.
Warning: through the controlling signal, the maximum charging current borne by
the vehicle shall not exceed the maximum charging current specified by the EPC
controller, otherwise personal injury or property loss will be caused.
Notice
L/N is connected to the main board’ s line.
5.1 Connecting terminal blocks and terminal assignment
“C: with cable version”means that the charging cable is permanently connected
to the controller; P1 / P2 terminal is connected to the AC contactor providing
the charging load. The rated value of Curve B circuit breaker shall be
selected within the maximum current range circuit breaker shall be selected
within the maximum current range.
Notice
When selecting the cable, its temperature resistance needs to be at least 75°C. If the temperature resistance fails to meet the requirements, personal injury or property loss will be caused. Warning: The conductor sections should be designed to conform to the standard system construction. The cable must conform to the type of line, otherwise it will cause personal injury or property loss.

Functional grounding Vehicle interface shall conform to IEC61851
- Connect“CP”directly to the interface of vehicle charging terminal.
- Firstly connect the ground wire (PE line) of the vehicle charging terminal interface to the OV control point of the EPC controller, and then connect other lines in order. Do not use terminal blocks or EPC controller to connect the device from the outside at OV control point.
OV control point shall be consiste nt with the expected current of the factory. The connection of EPC controller to OV is functional grounding, and the reliability of connection must be guaranteed,otherwise personal injury or property loss will be caused.
Relay output
We recommend connection with 230 / 400V 10kA curve B RCCB. Cutting off the
power branchAccording to IEC61851, it is required to cut off the power branch
when the charging process is completed within 100ms.
The EPC controller will stop the relay output after detecting that the power
branch is cut off.
Warning: To cut off the power branch, especially the contactor, the total
power-off time shall not exceed the required 100ms.
Replacement device
Maintenance
EPC charging controller is maintenance free.
Warning: There is no replaceable fuse inside EPC When replacing, make
sure that the device and the components associated with the device are not
energized.
Danger: Voltage hazard Touching any running parts will cause serious
injury. Please cut off the power before operation.
Process
- Cut off the line from the EPC controller terminal.
- Pull the latch down from the back of the unit and rotate until it is free of the DIN rail and removed.
- Installation: connect the rear lock clipper to the DIN rail and swing until the lock clipper was put in.
- Reconnect the line (On).
- Turn on the switch and the main power.Cleaning Cleaning of the unit is not allowed
