Instructions for Use
1. When using this product, users should wire it correctly as shown in Figure 1;
When the connected phase line is in positive sequence, the bright spot of the indicator light rotates clockwise, and the positive sequence relay is delayed in closing; On the contrary, the indicator light will rotate counterclockwise, and the reverse sequence relay will delay the closing; The two relays are electrically interlocked.
3. When the power is turned on, the indicator lights corresponding to each phase light up; If there is a shortage, the indicator light corresponding to this phase will turn off, and the bright spot of the indicator light will stop rotating. At the same time, the original pull in relay will be delayed and released, so that both relays are in the released state.
