Note that only two current inputs and two voltage inputs of the

ADE7752B are used in this case. The active power calculated by

the ADE7752B does not depend on the selected channels.

Figure 18 shows the connections of the ADE7752B analog

inputs with the power lines in a 3-phase, 4-wire Wye service.
