3.2 Installation Steps
- Mount the Controller: Securely mount the controller in a location that is protected from direct impact and excessive heat, ideally with good airflow. Ensure the mounting surface is stable.
- Connect Power Wires: Connect the main power wires (typically thicker red and black wires) from the battery to the controller, observing polarity.
- Connect Motor Wires: Connect the motor phase wires (typically three thicker wires, e.g., yellow, green, blue) from the controller to the motor.
- Connect Hall Wires: Connect the Hall sensor wires (smaller wires, often a bundle) from the motor to the controller.
- Connect Signal Wires: Connect all other signal wires according to the wiring diagram (e.g., throttle, brake, ignition, speed display, alarm, soft/hard start, gear level, reversing horn). Ensure each connection is firm and correct.
- Secure Connections: Double-check all connections for tightness and proper insulation. Use cable ties to manage wiring and prevent chafing.
- Initial Test: After all connections are made, turn on the vehicle's power and perform a low-speed test in a safe environment.

4. Operating Instructions
Once installed, the controller manages the power delivery to your motor based on your input.
- Power On/Off: Use the vehicle's main power switch or electric door lock to activate or deactivate the controller.
- Acceleration: Apply the throttle gradually for smooth acceleration. The controller's soft start function helps prevent sudden jerks.
- Speed Control: Utilize the three-speed function (if connected) to select appropriate speed gears for different driving conditions (e.g., low speed for crowded areas, high speed for open roads).
- Braking: The controller is designed to provide enhanced sensitivity for braking. Engage the brakes as needed; the controller will manage motor power accordingly.
- Reversing: If a reversing horn/switch is connected, activate it to engage reverse gear.
- Monitoring: Pay attention to any indicator lights or meter readings (if connected) for system status and battery voltage.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your motor controller.
- Keep Clean: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can affect heat dissipation.
- Inspect Wiring: Regularly check all wiring connections for signs of wear, corrosion, or looseness. Ensure waterproof seals are intact.
- Avoid Overheating: Ensure the controller has adequate ventilation. Avoid operating the vehicle in conditions that cause prolonged overheating of the controller.
- Battery Health: Maintain your vehicle's battery in good condition. The controller's under-voltage protection relies on accurate battery voltage.
- Environmental Protection: While the controller has an IP55 rating, avoid prolonged exposure to extreme moisture or submersion.
