Connect the fan today, there is a capacitor and three wires (red, yellow and green) on it. How to connect them, and the significance of the three lines into the fan.

1. The three lines of the fan capacitor are the yellow capacitor rotor control line, the red power line and the blue zero line that control the rotation of the fan.

2. Connect the blue line of the fan with the rotor control line of the capacitor, and connect the black line with the power line of the capacitor.

3. After the connection, the remaining red wire is connected to the power supply, that is, the live wire of 220V, and then one of the remaining two wires is connected to the zero line of the power supply, so that a loop can be formed, and the capacitor plays the role of starting the capacitor.

4. Connect the capacitor of the fan with the fan.
