4.2 Conexións eléctricas
Refer to the wiring diagram provided with your speed controller for specific connection details. General steps include:
- Connect the Motor to the Controller: Connect the motor's power wires to the corresponding output terminals on the speed controller. Pay close attention to polarity.
- Connect the Battery to the Controller: Connect your 48V DC power source (battery) to the input terminals of the speed controller. Ensure correct polarity (positive to positive, negative to negative).
- Connect the Throttle Pedal: Plug the throttle pedal's connector into the designated port on the speed controller.
- Connect Other Accessories: If applicable, connect any other accessories (e.g., ignition switch, brake sensors) to their respective ports on the controller as per the wiring diagram.
- Secure all Connections: Double-check all connections for tightness and proper insulation. Loose connections can lead to poor performance or electrical hazards.
4.3 Control direccional
The motor supports both forward and reverse rotation. To change the direction of rotation, reverse the polarity of the motor's power wires connected to the speed controller. Consult your controller's manual for specific instructions on directional control if it offers a dedicated switch or wiring for this function.

5. Instrucións de funcionamento
Once the motor and controller are correctly installed and wired, follow these steps to operate the system:
- Encendido: Insert the key into the ignition switch (if included) and turn it to the 'ON' position. The system should power up.
- Proba inicial: Before full operation, perform a brief test. Gently press the throttle pedal to ensure the motor spins smoothly and in the desired direction.
- Control de velocidade: The throttle pedal provides variable speed control. Pressing the pedal further increases the motor's speed up to its maximum 4500 RPM.
- Apagado: To stop the motor, release the throttle pedal and turn the ignition key to the 'OFF' position.
