5. 설정 및 설치
Proper installation is crucial for the safe and effective operation of your hardwire kit. If you are unsure about any steps, it is recommended to seek professional assistance.
5.1 안전 예방 조치
- Always ensure the vehicle's ignition is OFF before beginning installation.
- Disconnect the vehicle's battery negative terminal if you are uncomfortable working with live electrical circuits.
- Carefully test and check the polarity and grounding of your vehicle's electrical system before making connections.
- Do not expose the hardwire kit to moisture or extreme temperatures.
5.2 배선도view
The hardwire kit features two input wires for connection to your vehicle's power source:
- Red Wire (ACC/Battery+): Connects to a switched 12V-24V power source (e.g., an ACC fuse in your fuse box) that turns on and off with the vehicle's ignition.
- White Wire (GND/Battery-): Connects to a reliable ground point on the vehicle's chassis.

5.3 설치 단계
- 전원 공급원을 확인하십시오: Locate your vehicle's fuse box. Using a circuit tester, identify a fuse that provides switched power (ACC) and a suitable ground point (metal chassis).
- Connect Power Wire: Use a fuse tap (not included) to connect the red wire (ACC/Battery+) of the hardwire kit to the identified switched power fuse.
- 접지선을 연결하십시오: 안전하게 연결 white wire (GND/Battery-) to a clean, unpainted metal bolt or screw on the vehicle's chassis. Ensure a good electrical connection.
- 케이블 경로: Carefully route the Micro USB cable from the power converter box to the location of your device (e.g., dash cam). Ensure the cable is tucked away neatly and does not interfere with vehicle operation or safety features.
- 장치 연결: Plug the right-angle Micro USB connector into your dash camera, GPS navigator, or other compatible 5V device.
- 테스트 기능: Turn on your vehicle's ignition. Your connected device should power on. If not, recheck all connections.

6. 사용 설명서
Once installed, the EKYLIN DC 12V to 5V Micro USB Hardwire Kit operates automatically:
- When the vehicle's ignition is turned on, the hardwire kit will supply 5V power to your connected device.
- When the vehicle's ignition is turned off, the hardwire kit will cease power supply to the device.
- The built-in low car battery voltage auto cut-off feature will automatically stop power delivery if your vehicle's battery voltage drops below approximately 11.2V, preventing complete battery discharge. Power will resume when the voltage reaches approximately 11.6V.
