Get rid of the interconnecting links one by one.

The output of the UPS will most likely be connected into an automatic switching panel - just conectors with their sensing coils connected accross opposing circuits.

just find the panel it goes into it and isolate from there

Before you switch off the mains isolator you had better

1- switch off the battery charging circuit
2- isolate the batteries

Ian,

With regards to the mains isolator. Do you mean switch off the input isolator or the output?
Assuming there are both that is.

I believe this thing is digitally controlled. Has anyone ever worked on one of these? Anyone know where I could find a manual for it?

I found the manual here btw: http://lit.powerware.com/ll_download...0B4000-ENG.zip

This is for the Powerware Borri 4000 which is apparently the same unit.

Switch off every thing you can find giz,test it ,make sure everythings dead ,test between phases ,phase to earth and phase to neutral,this thing may have more than one supply.
and be confident reading manuals will just confuse you ,read the previous posts ,and go and get the job done ,you cant woory about every job you might do in the future,
all the best with it.

It Cant Hurt You If Its Dead.

Link for product info http://www.hkectr.com/photo/products...3/S4000new.pdf I would speak to specialist UPS recycling company before attempting to move it, the are usually lead acid batteries and hence will have to be upright at all times to avoid leakage.

Thanks everyone,

I persuaded the boss that it needed done properly and he got a company to remove it. (backroom.co.uk if anyone is interested) Very proffessional and the cost was reasonable.

Cheers
