5. Setup and Installation
Installing the controller system requires careful attention to wiring and component placement. It is strongly recommended that installation be performed by a qualified technician or someone experienced with electric scooter electronics.
General Installation Steps:
- Preparation: Ensure the scooter is turned off and the battery is disconnected. Gather all necessary tools (screwdrivers, wire cutters, electrical tape, etc.).
- Access Components: Carefully open the scooter's deck or housing to access the existing controller and wiring.
- Remove Old Components (if replacing): Disconnect and remove the old controller, display, and other parts being replaced. Note the original wiring configuration.
- Install New Controller: Mount the new 36V 350W Brushless Motor Controller securely in the designated area.
- Connect Wiring: Connect the main control cable to the controller. Then, connect the display, switch, accelerator, brake, and front light to the appropriate ports on the control cable or directly to the controller as per the scooter's wiring diagram. Ensure all connections are firm and correctly matched (e.g., motor phase wires, Hall sensor wires, power input).
- Secure Components: Install the new display, switch, accelerator, brake lever, and front light in their respective positions on the handlebars and frame.
- Initial Test: Before fully reassembling the scooter, reconnect the battery and perform a preliminary power-on test. Check if the display lights up, the accelerator responds, and the brake cuts power.
- Reassembly: Once functionality is confirmed, carefully reassemble the scooter's housing, ensuring no wires are pinched.
Note: Different batches of products may have slight variations in appearance or color, but this does not affect their functionality or compatibility with the KuGoo Kirin S8 Pro.
