3. Safety Precautions

• Always disconnect the battery before performing any installation, maintenance, or repair work on your e-bike.
• Ensure all connections are secure and properly insulated to prevent short circuits.
• Do not expose the controller to water or extreme temperatures.
• If you are unsure about any part of the installation process, consult a qualified technician.
• Wear appropriate safety gear, including gloves and eye protection, when working with electrical components.

4. Installation Guide

Carefully follow the wiring diagram below to connect the controller to your e-bike components. Ensure each connection is made to the correct corresponding part.

Wiring Connections:

1. Power Supply: Connect to the e-bike battery. Ensure correct polarity.
2. Throttle: Connect to the e-bike's throttle mechanism.
3. Assistance (PAS Sensor): Connect to the Pedal Assist System sensor.
4. Speed Signal: Connect to the speed sensor for accurate speed readings.
5. Brake (5 & 6): Connect to the e-bike's brake levers. These typically cut motor power when brakes are applied.
6. Brake Light/Rear Light (7): Connect to the brake light or rear light system.
7. Motor Hall: Connect to the motor's Hall sensors.
8. Horn Switch (9): Connect to the e-bike's horn switch.
9. Headlight and Horn (10): Connect to the e-bike's headlight and horn.
10. Display (11): Connect to the compatible 5S display meter.
11. Motor Cable (12, 13, 14): Connect the three phase wires to the e-bike motor. Ensure these are correctly matched.

After making all connections, double-check for any loose wires or incorrect pairings before powering on the system.

5. Operation

Once the controller is correctly installed and all components are connected, power on your e-bike. The display meter (if connected) should illuminate and show relevant information. The controller will manage the power delivery to the motor based on throttle input and pedal assistance (if enabled). Familiarize yourself with your e-bike's display and throttle operation for a smooth riding experience.

6. Maintenance

• Regularly inspect all wiring connections for signs of wear, corrosion, or looseness.
• Keep the controller clean and free from dust, dirt, and moisture.
• Avoid exposing the controller to direct sunlight for extended periods or extreme heat.
• Do not attempt to open the controller casing, as this may void any warranty and could damage internal components.

7. Troubleshooting

If you encounter issues with your e-bike's motor or electrical system, consider the following common troubleshooting steps:

• No Power to Motor: Check battery charge, ensure all power connections (including the main power supply to the controller) are secure. Verify the display is receiving power.
• Motor Not Responding to Throttle: Check throttle connection and functionality. Ensure the speed signal and assistance sensor connections are correct.
• Erratic Motor Behavior: Inspect motor Hall sensor connections and motor phase wire connections for proper seating and damage.
• Display Not Working: Check the display's power connection to the controller.
• Brakes Not Cutting Power: Verify brake lever switch connections (5 & 6) are correctly installed and functioning.

For persistent issues, it is recommended to consult a professional e-bike technician.
