Wieing diagram
connection method
1、Controller voltage U1 and U2 connect with B phase and C phase.(See diagram 1 and kiagram2)
2、Sampling current terminal l1 and l2 are getting from A phase current transformer sublevel If the total load(major cabinet),never get from the capacitance screen.
3、COM is the common source of inner relay of output terminal 1~10groups of the contuoller, AC contactor J coil voltage 220V.
