Specification
| Item | Specification |
| Rated voltage (V) | 120 - 230 |
| Rated current (A) | 6, 8, 10, 12 (Variable Settings) |
Description
• A device designed to provide assistance with AC charging (at home).
• The ICCB has functions such as indicating the state of charge, blocking and detecting leakage current, blocking power when the internal temperature is abnormal, detecting over-current, blocking power plug when the temperature is abnormal, and automatically varying current down.
Indicator Description
| Name | Indicator | Function |
| POWER indicator |
|
Illuminates green when the power plug is connected |
| CHARGE indicator |
|
- Illuminates blue during AC charging - Blinks blue during charging with lower current |
| FAULT indicator |
|
Blinks red when charging stops due to a failure (e.g., leakage current or over current) |
| 7 - segment |
|
- Displays charging current or DTC - Blinks in charging current selection mode |
Troubleshooting
Lighting signal display during normal charging
| Order | Condition | Display mode | |
| 1 | Connecting the ICCB to the power plug : Power indicator light up and the charging current that is set is displayed in the 7- segment. | Standby mode |
|
| 2 |
ICCB connection to the vehicle's inlet and charging : If the ICCB is connected
to the inlet connector, the ICCB performs a self-examination for approximately
1.5 seconds, and if there are no problems, it activates ON the internal
relay, thereby becoming able to charge, and the charge indicator lights
up (charging satus). In charging status, if there are no changes for approximately
1 minute, the 7- segment charging current display turns OFF in order to
enter sleep mode. If the plug temperature is 80 - 90°C (176 - 194°F), or the internal temperature of the ICCB is 90 - 95°C (194 - 203°F), it enters the lowering mode of the charging current and the charging current becomes 6 A, making the charging indicator keep flashing ON and OFF. If after the lowering of mode of the charging current the temperature falls below 70°C (158°F), the original charging current value is restored. |

How to set the charging current
| Order | Procedure |
| 1 |
Entering the state of charge current setting Pressing the button in the standby or charged state for 2 to 8 seconds will enter the charging current setting state and the charging current value in the 7- segment will flash. |
| 2 |
Change the charging current The charging current is initially set at 6 A and is raised by one step each time the button is pressed (less than 1 second). When the current set value is 12 A, press the button to change to 6 A. Level 1 : 6 A → Level 2 : 8 A → Level 3 : 10 A → Level 4 : 12 A → Level 1 : 6 A |
| 3 |
Determining the charging current After setting the charging current, pressing the button for above than one second changes to the set value and switches from the charging current setting mode to the original mode (standby mode or charging mode). When there is no button input, it is returned to the previously set charging current value and switched to the original mode. |
In-Cable Control Box (ICCB) Self-diagnosis
The ICCB operation if there is a fault
| The ICCB operational specifications if there is a fault | Display mode | |
| The power indicator lights ON, the fault indicator flashes, and the fault code for the 7- segment lights ON. The power is turned OFF with the OFF of the internal relay. | Fault mode |

Fault code list of In-Cable Control Box (ICCB)
| Fault Code | Item | Suspected Cause | Inspection |
| E1 | CP communication | Vehicle communication fault occurred | Inspect the communication line and the ICCU |
| E2 | Leakage | Leakage current occurred |
E2 fault code (leaking current) remedy method: remove the power plug and
press the button for above than 2 seconds after reconnecting. ※ Repeat the procedures above 2 to 3 times and if the problem is not resolved, replace the ICCB. |
| E3 | Charger fault Occurred | Replace the ICCB | |
| E4 | Plug temperature | Power plug temperature 90°C (194°F) or above | |
| E5 | Power plug temperature rise more than 20°C (68°F) within 1 minute | ||
| E6 | Power plug temperature sensor fault | ||
| E7 | Overcurrent | Charge overcurrent warning | |
| E8 | Internal temperature | ICCB internal temperature 95°C (203°F) or above | |
| E9 | ICCB internal temperature sensor fault | ||
| F1 | Relay fault | Internal relay weld | |
| F3 | SMPS power fault | SMPS output voltage 8.5 V or below | |
| F4 | SMPS output voltage 8.5 - 11 V | ||
| F5 | CP voltage fault | CP ( - ) voltage fault | |
| F6 | CP ( + ) voltage fault | ||
| F7 | Temperature sensor fault | Plug temperature sensor fault | |
| F8 | PCB internal temperature sensor fault |
How to delete the past fault codes
| Order | Condition | Display specification | ||||
| Fault code call | The fault code call is possible when there is no fault indication in the standby mode. In order to call the history of past faults, press the button for above than 8 seconds. |
|
||||
| Deleting the saved fault code | After calling the fault code, if the button is pressed for above than 8 seconds, the fault code is deleted, and in the 7- segment, "NO" is indicated. Afterwards, it enters the automatic standby mode. |
|
