Operation method:
(1)Turn the speed rotary knob to zero
(2)Connect the main power,then turn on the switch of the controller(bright light)
(3)Adjust the potentiometer speed control knob, so that the motor can reach to your required speed.
Notes:
(1)Forbidden short-circuit output.
(2)The grounding line must be good contacted.
(3)Connect the neutral electrical to power zero line when using.
