Figure 18 shows the connections of the ADE7762 analog inputs
with the power lines in a 3-phase, 3-wire delta service.
Figure 19 shows the connections of the ADE7762 analog inputs
with the power lines in a 3-phase, 4-wire Wye service.

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.
