——Wire Connection Modes——


1.Fix the electric meter to the meter box, and connect the interface . It is recommended to use copper wire or copper terminal.

2.Voltage input: The input voltage should not be higher than the product’s rated input voltage of 220V, otherwise PT should be considered.

3.Current input: The standard rated input current is 5A. More than 5A, an external CT(Current transformershould be used. If other instruments are connected to the CT used, the wiring should be in series. Before removing the current input wire , be sure to disconnect the CT primary circuit or short the secondary circuit.

–Make sure that the input voltage and current correspond to each other in the same order, and the incoming and outgoing directions are the same; otherwise, the values and symbols will be wrong!
