Connect the DC power supply according to the wiring diagram. Ensure that the DC power supply voltage range is greater than 12V and less than 80V, and that the output power of the power supply meets the needs of the motor. The power supply voltage should be equal to the rated voltage of the motor.2. Connect the DC brushed motor according to the wiring diagram. The motor line can be positive or negative. When the running direction is inconsistent with the expectation, you can change the direction by adjusting the motor line sequence position.3. Do not reversely connect the positive and negative poles of the DC power supply, otherwise the governor may be damaged. Package List 1 x Motor Speed Controller 1 x English User Manual
