Not an answer to your question - just a question to your post

Any reason you are going for the APC UPS?
I've just spent a week deciding which UPS I was going to purchase for home use.
In the end I decided upon the Belkin 1200VA Universal UPS (which I managed to find for £89+vat).
I was tempted by the APC units but just found that I could get "more VA's for my money" looking at the Belkin units.
Just interested.
