3. Safety Information
Always adhere to the following safety guidelines to prevent damage to the power supply, connected devices, and to ensure personal safety:
- Ensure the power supply is used with compatible devices that match its voltage and current requirements (24V DC, 4A).
- Do not expose the power supply to water, moisture, or extreme temperatures.
- Avoid dropping or subjecting the power supply to severe impacts.
- Do not attempt to open or modify the power supply. Refer all servicing to qualified personnel.
- Disconnect the power supply from the main outlet before cleaning or when not in use for extended periods.
- Ensure proper ventilation around the power supply during operation to prevent overheating.

4. Setup and Installation
Follow these steps to correctly set up your Genmitsu Power Supply Adapter:
- Verify Compatibility: Confirm that your CNC router or spindle motor requires a 24V DC, 4A power input. This adapter is specifically designed for upgraded 20000RPM spindles compatible with 3018-PRO/PROVer/PROVer Mach3 and 4040-PRO/Reno CNC machines.
- Connect DC Output: Plug the DC output connector (barrel plug) of the power supply into the corresponding DC input port on your CNC router or spindle motor. Ensure a secure connection.
- Connect AC Input: Connect the AC power cord to the AC input port on the power supply. Then, plug the other end of the AC power cord into a standard wall outlet (100-240V AC, 50/60Hz).
- Power On: Once all connections are secure, you may power on your CNC router or spindle motor according to its specific operating instructions.

6. Maintenance
The Genmitsu Power Supply Adapter requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Keep the power supply clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Ensure that the ventilation slots are not blocked to allow for proper heat dissipation.
- Regularly inspect the power cords and connectors for any signs of damage, fraying, or loose connections. Replace if necessary.
- Store the power supply in a cool, dry place when not in use.
7. Troubleshooting
If you encounter issues with your power supply, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to spindle/CNC. | Loose connections, power outlet issue, faulty power supply. | Check all cable connections. Test the power outlet with another device. If still no power, contact support. |
| Spindle stutters or runs inconsistently. | Insufficient power, incorrect spindle settings. | Ensure the power supply is firmly connected. Verify spindle speed settings in your CNC software are appropriate for 20000RPM. This upgraded power supply is designed to prevent stuttering. |
| Power supply feels hot. | Poor ventilation, prolonged heavy load. | Ensure adequate airflow around the unit. Reduce continuous heavy load if possible. The built-in circuit helps manage heat. |
If the problem persists after attempting these solutions, please contact Genmitsu customer support for further assistance.
