how to use three-phase v-i measurement block from simpowersystems?

how to connect the three output terminals a,b,c of the three-phase v-i measurement blocks?

also my second question is how the active reactive power is calculated when we use active-reactive instantaneous power measurement block?

Best to check this example:

there is no output a,b,c. They are terminals to connect power lines, in the same way as A,B,C. The outputs are Vabc and Iabc, the measurements.
