Electrical Diagrams:
In the following picture we show as to connect the secondary side of current transducer.

The current transducer inlcudes a light signal to show normal operation state. The measure under this situation will be correct and inside of electrical parameters showed in the characteristics tables.
OUTPUT-INPUT Connector
Pin 1 : Output Current + ( Current Direction F to B)
Pin 2 : + Vcc Supply
Pin 3 : 0V ( General Reference of the circuit)
Pin 4 : - Vcc Supply
