The red signal lamp is used for motor operation and fault indication, and the green signal lamp is used for stop indication. White light is used to indicate the input and operation of reactive power compensation capacitors. The yellow light is used for star triangle operation indication and the red light is used for triangle operation indication.

In the "reset" button, blue, black, white or grey buttons are used for single function, while red buttons are used for stop and power off function.
