Maybe this will help someone in the future. We bought an Accurpress 7606 that was originally wired for 208V, then rewired to 480V, then we bought it and changed it back to 208V. First verify that your motors and control transformer have provisions for either voltage. For ours what needed to be changed was:

- Main fuses in the electrical cabinet
- Main motor overload (it's a little dial that can be adjusted for tripping current)
- Ram leveler overload (our dial didn't have a big enough range so had to get another one, only like $15 on ebay)
- Switching the input wires into control transformer to different lugs (the sticker on your transformer should say what lugs correspond to what input voltages)
- Rewiring the main motor from high voltage to low voltage setup (refer to sticker on motor wiring panel)
- Rewiring the ram leveler motor from high voltage to low voltage setup (refer to sticker on its wiring panel)

Your electrician (or you, I don't judge) should also verify the size of all your electrical cabinet wires going into the transformer and motors if your machine started its life as a 480V and you're dropping it to 208V (higher current).
