5. Installation and Setup
Before beginning installation, ensure your electric scooter's power is completely off and the battery is disconnected.
5.1 Mounting the LCD Display and Thumb Accelerator
- Identify a suitable position on your scooter's handlebar for the LCD display and thumb accelerator unit. The clamp is designed for a 22mm diameter handlebar.
- Loosen the screws on the clamp of the display unit.
- Position the display unit on the handlebar and tighten the screws securely. Ensure it is oriented for comfortable thumb operation and clear visibility of the screen.
5.2 Controller and Wiring Connections
The controller is the central unit for managing your scooter's motor and accessories. Carefully connect all wires as described below and illustrated in the wiring diagram. Pay close attention to wire colors and connector types.
- Motor Wires: Connect the three thick motor phase wires (typically Yellow, Green, Blue) from the controller to the corresponding motor wires.
- Hall Sensor Wires: Connect the smaller Hall sensor wires (typically a 5-wire connector) from the controller to the motor's Hall sensor connector. Ensure correct polarity.
- Battery Power: Connect the thick Red wire from the controller to the positive (+) terminal of your scooter's battery, and the thick Black wire to the negative (-) terminal.
- LCD Display (Instrument Cable): Connect the 6-pin instrument cable (provided) from the LCD display unit to the corresponding port on the controller. This cable typically carries power, communication, and control signals.
- Throttle (Thumb Accelerator): The thumb accelerator is integrated with the LCD display and connects via the instrument cable.
- Brake Levers: Connect the brake lever wires (if applicable) to the designated brake input on the controller. These typically cut motor power when brakes are applied.
- Other Accessories: Connect any other accessories (e.g., lights, horn) to their respective ports on the controller, if available and compatible.
After making all connections, double-check for security and correct pairing. Ensure no bare wires are exposed. Secure the controller in a safe, dry location on your scooter.
