It sounds like one of your hots isn't hot. So perhaps it's operating at 120 V when your are expecting 240 V. Check your outlet and/or wiring.I also noticed that under 110v I need to have the hot leg in a specific position for it to work, which seemed odd at the time.
Please check very carefully before powering it up. The way you thought it was seems it would have connected a hot to chassis, which you should have noticed painfully, and returning through ground should have tripped your GFCI, I would think.I think I found the problem. ... So, I was feeding one hot leg in (red) and returning through ground, which is a bad idea.
I haven't hooked it back up yet...

Is the output fuse blown on the right hand unit, can't really see it in the picture.
where are you located--don't know what mains system you are using.
Who wired up the plug? Who wired up the mains outlet--is it in the correct polarity and configuration?
