2.5ELECTRICAL CONNECTION INSTALLATION

Choose the diagram that best suits your application and maintain the polarity. Follow the outlined procedure to verify correct connection.

NOTE: THE NEUTRAL READING IS CALCULATED FROM THE SUM OF THE 3 PHASES OF CURRENT. HIGH NEUTRAL CURRENT INDICATES REVERSE CT POLARITY.
