Operating instruction:
Connect DC motor (or DC load) to the motor terminals as indicated on the wiring diagram;
Connect a voltage of 6V-28V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit;
Turn on the power, the power LED lights, the power is OK;
Adjust the potentiometer, motor speed can be controlled.

Important notes:
An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation.
The controller is NOT reverse-polarity protected and it will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes.
