As shown in the figure above, in the control mode, when the SB1 button is closed,
press the SB2 button to turn the inverter forward. Press the SB3 button to reverse the
inverter. When the SB1 button is turned off, the inverter stops. During normal start-up
and operation, it is necessary to keep the SB1 button closed. The commands of the SB2
and SB3 buttons are valid at the end of the closing action. The running status of the
inverter is based on the last button action of the three buttons.
