Question,
If I connect my main AC2 transformer to the UPS, and purchase a secondary transformer(with the 9-volt connector) to my AC2 battery back up, will this cause a ground loop, or what if the transformers are not plugged into to the same ac "Phase".
I currently have 8 outlets on 2 dedicated circuits (1 GFCI on each leg of AC, with a second outlet piggy-backed to it). Will this harm my AC2 unit? either:
A) plugged into UPS, and wall outlet on the same ac phase, or
b) plugged into UPS, and the the other wall outlet on the other AC phase?
Confused?
