4. Safety Information
Always observe the following safety precautions to prevent injury or damage to the controller and associated equipment:
- Ensure the power supply is disconnected before performing any installation, wiring, or maintenance.
- Verify that the voltage and current ratings of your battery and motor are compatible with the controller's specifications.
- Avoid exposing the controller to water, excessive moisture, or extreme temperatures.
- Do not attempt to open or modify the controller casing, as this may void the warranty and pose electrical hazards.
- Consult a qualified technician if you are unsure about any installation or wiring procedures.
5. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your FarDriver ND72300 controller. Follow these steps carefully:
- Mounting: Securely mount the controller to the frame of your electric bike in a location that allows for adequate airflow for cooling and protection from physical damage and moisture. Refer to Figure 4 for dimensions.
- Power Connections:
- Connect the main battery positive (B+) cable to the red terminal on the controller.
- Connect the main battery negative (B-) cable to the black terminal on the controller.
- Ensure all power connections are tight and secure to prevent arcing or overheating.
- Motor Connections:
- Connect the motor phase wires (U, V, W) to the corresponding terminals on the controller (typically yellow, green, blue).
- Connect the motor Hall sensor wires to the multi-pin connector using the provided wiring harness (refer to Figure 3).
- Signal and Control Wiring: Connect the throttle, brake levers, ignition, and other control signals using the wiring harness. Consult the specific wiring diagram provided with your electric bike kit or motor for detailed connections.
- Initial Power-Up: After all connections are made and verified, connect the battery. Observe for any unusual sounds or smells. If issues arise, immediately disconnect power and re-check all connections.

6. Operating Instructions
Once the controller is correctly installed and all connections are secure, you can begin operating your electric bike:
- Power On: Turn on the electric bike's main power switch. The controller will perform a self-check.
- Throttle Control: Gently apply the throttle to initiate motor rotation. The controller will regulate power delivery based on throttle input.
- Braking: Engaging the brake levers will cut power to the motor, ensuring safe stopping.
- Monitoring: Pay attention to any indicators on your electric bike's display (if equipped) for battery level, speed, and error codes.
For advanced settings or customization, refer to the specific software or programming guide for the FarDriver series, typically available from the manufacturer's support resources.
7. Maintenance
The FarDriver ND72300 controller is designed for minimal maintenance. However, regular checks can ensure its longevity and reliable performance:
- Visual Inspection: Periodically inspect the controller for any signs of physical damage, loose connections, or corrosion.
- Cleaning: Keep the controller clean and free from dust, dirt, and debris. Use a dry, soft cloth for cleaning. Do not use water or chemical cleaners.
- Connection Checks: Ensure all electrical connections remain tight and secure. Loose connections can lead to intermittent operation or damage.
- Heat Management: Ensure the controller's heat sink fins are not obstructed, allowing for proper heat dissipation.
8. Troubleshooting
If you encounter issues with your FarDriver ND72300 controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not run | No power, loose connections, faulty throttle, motor or Hall sensor issue. | Check battery connection and charge. Verify all wiring connections (power, motor phases, Hall sensors, throttle). Test throttle functionality. Inspect motor for damage. |
| Intermittent power/operation | Loose wiring, poor contact, overheating. | Tighten all connections. Ensure controller has adequate ventilation. Check for signs of overheating. |
| Controller gets excessively hot | Overload, insufficient cooling, short circuit. | Reduce load on the motor. Ensure controller is mounted in a well-ventilated area. Check for short circuits in motor or wiring. |
| Unusual noises from motor | Incorrect motor phase connection, Hall sensor issue, motor damage. | Verify motor phase and Hall sensor wiring. Consult a technician if motor damage is suspected. |
If the problem persists after attempting these solutions, please contact customer support for further assistance.
