On the front panel door control indicator (red Third from bottom) , show lack of phase or phase sequence ( Gating) When, on behalf of the phase sequence protection or lack of phase. In order to guarantee the power supply to the use of security, stability, our power setting the phase sequence protection and open phase protection function. Meet phase sequence with errors or lack of phase, in order to prompt the user lacks protector the red light, the power supply cannot work normally. The so-called 'phase sequence protection' refers to the three phase line when the three-phase power supply order mistake, power supply automatic protection function.
