Can anyone link a basic design guide for UPS systems?
It would be much appreciated.
Thanks.

RE: UPS Systems
RE: UPS Systems
My building voltage is 277/480,3ph,4w and they need a panel which is UPS protected. So I can connect this like a transformer?
I'm not sure how to show this on a one-line. Just like a transformer?
I assume it would be like a generator with a transfer switch which would switch over to the UPS?
RE: UPS Systems
Yes, see page 3 of this link http://www.sandc.com/pdfs/600/653_30.pdf
RE: UPS Systems
Does the UPS have the isolation transformer integral to it? Does it also have the circuit breakers integral?
I only need one panel (computer loads) connected to a UPS. So, would I connect thru the UPS or have a transfer switch. I am assuming directly thru it.
RE: UPS Systems
Yes
[Does it also have the circuit breakers integral?]
Yes, everything shown on the diagram is included, you only need to bring in the utility power source and the cables to the load.
[I only need one panel (computer loads) connected to a UPS. So, would I connect thru the UPS or have a transfer switch. I am assuming directly thru it.]
Then bring the cable from the panel originally destined to the computer loads to the UPS instead, and the output of the UPS to the loads.

Try IEEE Std 446, Recommended Practice for Emergency and Standby Power Systems for Industrial and Commercial Applications.

Heres a cheap one for you. I have noticed that some of the Army manuals are the same as the IEEE standards.
