Guía de conexión:

1. Conexión do motor: Connect the three thick phase wires (typically Green, Blue, Yellow) from the controller to the corresponding motor phase wires. Connect the smaller Hall sensor wires (Red, Black, Green, Blue, Yellow, White) to the motor's Hall sensor connector (C4 in Figure 3).
2. Conexión da batería: Connect the thick Red wire from the controller to the positive (+) terminal of your 36V or 48V battery, and the thick Black wire to the negative (-) terminal.
3. LCD Display (Optional): If using an NB POWER LCD display, connect it to the designated connector (C7 in Figure 3). This connection is required to activate the regenerative function.
4. Conexión do acelerador: Connect the throttle unit to the throttle connector (C8 in Figure 3). This typically has Red (5V), Black (Ground), and White (Signal) wires.
5. PAS (Pedal Assist System) Connection: Connect the PAS sensor to its dedicated connector (C5 in Figure 3). This usually includes Red (5V), Yellow (Signal), and Green (Ground) wires.
6. Brake Levers Connection: Connect the brake levers to the brake input connectors (C6 in Figure 3). These are typically LOW-LEVEL brake inputs.
7. Other Connections (C1, C2, C3): These may include wires for specific functions like ignition lock, cruise control, or other accessories depending on your ebike system. Refer to your ebike's specific wiring diagram if these are present.

After all connections are made, double-check for correctness and secure fitment before reconnecting the battery power.

6. Instrucións de funcionamento

Once the controller is correctly installed and the battery is connected, your ebike system should be ready for operation.

• Encendido: Turn on your ebike's power switch (if applicable) or the LCD display.
• Control do acelerador: Gently twist the throttle to engage the motor. The speed is regulated by the throttle input voltage (1-4.2V).
• Asistencia de pedal: If a PAS sensor is installed, pedaling will activate motor assistance. The level of assistance may be adjustable via your LCD display.
• Freado: Engaging the brake levers will cut off motor power, ensuring safe stopping.
• Regenerative Function: If using a compatible NB POWER LCD display, the regenerative braking function can be activated through the display settings. This function allows the motor to act as a generator during braking or downhill riding, returning a small amount of energy to the battery.

7. Mantemento

Proper maintenance ensures the longevity and reliable performance of your controller.

• Manter seco: Ensure the controller remains dry and protected from water ingress.
• Limpeza: Periodically clean the exterior of the controller with a dry cloth to remove dust and debris.
• Inspeccionar conexións: Regularly check all electrical connections for tightness and signs of corrosion or damage.
• Temperatura: Avoid operating or storing the controller in environments outside its specified operating temperature range (-40°C to 80°C).
