4. Setup and Installation
Proper installation is crucial for the safe and effective operation of your electric scooter or bicycle. If you are unsure about any step, it is recommended to seek professional assistance.
4.1. Safety Precautions
- Always disconnect the battery power before beginning any installation or maintenance.
- Ensure all connections are secure and properly insulated to prevent short circuits.
- Wear appropriate safety gear, such as gloves and eye protection.
- Refer to your electric scooter/bicycle's original manual for specific wiring diagrams if available.
4.2. Installation Steps
- Mount the Controller: Securely mount the motor controller to the frame of your electric scooter or bicycle using appropriate fasteners. Ensure it is in a location that allows for good airflow for cooling.
- Connect Motor Wires: Connect the motor phase wires (usually three thick wires, often green, blue, yellow) from the controller to the corresponding wires on your motor.
- Connect Hall Sensor Wires: Connect the Hall sensor wires (usually five thinner wires) from the controller to the motor's Hall sensor connector.
- Connect Battery Power: Connect the main power wires (red for positive, black for negative) from the controller to your battery. Ensure correct polarity.
- Connect LCD Display: Connect the wiring harness from the LCD display unit to the corresponding connector on the controller.
- Connect Other Accessories (Optional): Connect any other accessories such as brake levers, lights, or pedal assist sensors (PAS) to their respective connectors on the controller.
- Secure All Connections: Double-check all connections to ensure they are tight and properly insulated. Use cable ties to manage wires and prevent them from interfering with moving parts.
