Re: Power Connection Question

I'm quite sure the 620 will be unhappy with 120V. 'The Book' on those
systems says 200 to 240V 50 or 60hz. There is a UPS integrated into the
PDU for that system (from Deltec) and I suspect that won't even light
off at 110V. As to single .vs. 3 phase I'm quite certain it will run on
3 phase though technically you will be running on 2 out of the three
phases. Some UPSs will not even start in that mode as they detect 'input
phase rotation but I don't think the deltec units cared.. This is where
the two legs are out of phase which they certainly are (on purpose!)
with 3 phase.

I guess I'd plug it into 110V and see what it does (or doesn't) do.
