I'm trying to get two old UPS units to work. They
were made by Best
Electric / Best Power Technologies and apparently, that firm (in Necedah
WI) has changed hands at least twice. Entering www.bestpower.com into a
browser gets you an immediate redirect to
http://www.powerware.com/UPS/BestPower/Products.asp, an Eaton company,
which knows nothing at all about these units.
I've got a model ME2.1KVA unit that needs four 12V, 35Ah batteries. I
think it works, I just can't afford the batteries. Best price I've seen is
about $49. The UPS is huge-- about 18 inches front to back, and darn near
two feet high.
I also have a ME700VA unit that uses the same battery, just one of them.
Both have serial ports and lots of dipswitches.
Anyone know where to find a manual for these?
Well I'll be dipped. The direct approach paid off! I sent an email to Eaton
via their "Contact Us" form on their website, which I reached by trying to
reach www.bestpower.com, being redirected to
http://www.powerware.com/UPS/BestPower/Products.asp?CC=1 (Service and
support --> Contact Support) and finding the BestService at eaton.com email
address. Or maybe it went to http://www.powerware.com/USA/contact It's hard
to tell.
Anyhow, someone at BestService at eaton.com sent me a 27-page PDF with most of
the user-side documentation. It includes a pin-out of the DB-25 connector
on the back, and the command guide.
