Make 240V from two 120V units?

[mlewis_apc]

I have a weird problem on my hands and need some input which would be most appreciated.
In my main server room, I have an RT10000RMXL unit handling a small network.

I am building a new network and I need to migrate everything over which will take several weeks.
My problem is that I don't have a second UPS which has a 208/240 output yet a couple of the hardware items require 240VAC for power.
I don't have the budget to purchase another unit, especially only for a short term use.

I do have several SU3000RM3U units which are sitting idle at the moment. My question is one which I almost certainly know the answer to :).

Could I use two of the 120V units in order to get a safe 240V output in order to secure the load at the new location until I get the RT10000RMXL unit moved over to the new location.

I realize that each unit would only be able to monitor it's own outputs of 120V so while I could probably wire two outputs to get 240V, I suspect this would not be safe, even for a few weeks?

i think the biggest issue you'd have is national electrical code and/or local electrical code. as long as the UPS gets 208v or 240v input, i don't think you'll have an issue with UPS powering on that its just the safety issue like you said. i can't comment on it from experience or anything but i imagine its not a good idea.

The problem I am facing is that I only have one UPS which inputs 240v and outputs 240V.
I do have several 120V in/out units and that's why I wondered if I could in fact use two of those to get the 240V I need temporarily.

So there is no way of doing this, even for a temporary, one month solution?

I've decided not to bother so buying a second ups.
