Hookup Data:
For Parallel connected operation (33.8K Ohm Secondary): Connect the GRN/YEL wire to the GRN wire AND the BLK/YEL wire to the BLK wire.
For Series connected operation (135K Ohm Secondary): Connect the BLK/YEL wire to the GRN (this becomes the center tap) - GRN/YEL and BLK wires are the output.
