3. Safety Information
- Always disconnect power before installation, maintenance, or troubleshooting.
- Ensure all connections are secure and properly insulated to prevent short circuits.
- Do not expose the controller to water or extreme temperatures.
- Verify that the voltage and power ratings of your motor and battery are compatible with this controller.
- Seek professional assistance if you are unsure about any installation steps.
4. Setup and Installation
Carefully follow these steps to install your brushless motor controller. Refer to the labels on the controller's interfaces and the provided diagrams for correct connections. Incorrect wiring can damage the controller or other components.

Connection Steps:
- Motor Cables (A, B, C): Connect the three thick motor phase wires (typically green, yellow, blue) from the controller to the corresponding motor phase wires. Ensure colors match.
- Hall Sensor: Connect the Hall sensor wire bundle (usually a 5-wire connector) from the controller to the motor's Hall sensor connector.
- Battery Connection:
- Battery Positive Electrode: Connect the red wire from the controller to the positive terminal of your 24V battery.
- Battery Negative Electrode: Connect the black wire from the controller to the negative terminal of your 24V battery.
- Speed Steering Handle (Throttle): Connect the throttle connector (typically a 3-wire connector) to the speed control handle.
- Low Potential Brake: Connect the brake signal wire(s) to your brake levers. This connection typically cuts power to the motor when brakes are applied.
- Assist Sensor (PAS): If your electric bicycle has a pedal-assist system, connect the assist sensor wire to the corresponding connector.
- Intelligent Identification (Self-Learning Wires): These two wires (often white or green) are used for initial motor direction setup. Connect them, power on, and the motor will spin. If it spins in the wrong direction, disconnect, reconnect, and power on again. Once the correct direction is established, disconnect and leave them disconnected.
- Cruise Function: If your system supports a cruise control function, connect the cruise function wires.
After all connections are made, double-check each wire against the labels and diagrams before applying power.

5. Operating Instructions
- Ensure all connections are secure and the battery is charged.
- Turn on the main power switch of your electric vehicle.
- Use the speed steering handle (throttle) to control the motor's speed.
- Apply brakes as needed; the controller will cut power to the motor when the brake signal is received.
- If equipped, engage the cruise function for maintaining a constant speed.
6. Maintenance
- Keep the controller clean and free from dust and debris.
- Regularly inspect all wire connections for looseness or damage.
- Avoid exposing the controller to direct sunlight for prolonged periods or to environments with high humidity.
- Do not attempt to open the controller casing, as this may void any warranty and could lead to damage.
7. Troubleshooting
- Motor Not Responding: Check battery charge, ensure all power connections are secure, and verify throttle connection. Re-check the intelligent identification wires if motor direction was an issue.
- Intermittent Power: Inspect all wiring for loose connections or damaged insulation. Ensure the battery is providing consistent voltage.
- Overheating Controller: Ensure the controller is mounted in a location with adequate airflow. Verify that the motor is not drawing excessive current due to a fault or overload.
- Brakes Not Cutting Power: Check the low potential brake wire connection and ensure the brake levers are functioning correctly.
