Choice #1 (115 VAC Input):
For those customers who need the 115V input - nothing has changed - simply use the White & Gray wires and tape the Black wire (see above schematic).
Choice #2 (125 VAC Input):
For those customers who are seeing too high a secondary voltage due to higher primary line voltages (roughly 125V input) - use the White & Black wire and tape the gray wire
Caution: NEVER connect power to BOTH the GRAY & BLACK wire - instantaneous destruction of the transformer will result!
