使用说明Directions
1、用户在使用本产品时，应按照图一所示正确接线：

User should properly connect according to figure I while using Theis product.

2、当接入相线为正序时，批示灯亮点按顺时针旋转，同时正序继电器延时吸合，反之，则指示灯亮点接逆序时针旋转，同时逆序继电器延时吸合，两继电器有电气连锁。

The lamp will sequence turn on clockwise when the connect power is RF correct,meanwhile relay of RF correct will close,otherwise the lamp will sequcnce turn on anticlockwise while the RF false relay will be close,two relay are electrical connected.

3、当接通电源后，各相所对应的指示灯点亮，如有缺相时对应此相的指示灯会熄灭，且指示灯亮点停止旋转，同时原吸合继电器延时释放，从而使两继电器都处于释放状态。

After connecting to the power,the phase-indicated-lamp should be rurn on,if one phase loses,then responded lamp will be off,and sequence lamp will stop work and the relay will open,and two relay all in open status.
