The i nte llige nt co nt ro lle r ca n a uto matica lly co nt ro l the starter to run according to the predetermined program , there by completing the star delta starting of the motor .
The YCFK intelligent capacitor switching device uses thyristor switch and magnetic holding switch in parallel operation.
It has the advantage of controllable silicon zero-crossing switch at the moment of connection and disconnection, and zero power consumption of the mag- netic holding switch during normal connection.

1.To prevent electric shock,the power must be off when wiring isto be carried out
2.Wiring shall be arranged directly according to ports. Please confirm whether allconnections are correct.
3.Use drag steering.
4.To reduce electromagnetic interference to electrical wires,
equipment and wires shall be connected in suitable range with same size for shortest connection.
5.Wiring layout shall be away from any internal electromagnetic nterference source.
6.The cross section of wires connecting power must be 0.5mm2-2.5mm2(20-14AWG;75℃(min)).And the current load of the wires shall be 6A.
7.Copper wire (standard or single core cable)can be used.
8.Before testing the equipment,please test the voltage and confirm whether it isproper
