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

ADE7762 are used in this case. The active power calculated by

the ADE7762 does not depend on the selected channels.

Figure 19 shows the connections of the ADE7762 analog inputs

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