Assuming that these UPSes are connected through USB and you're using the
'newhidups' driver (or the 'usbhid-ups' driver, if you're running the
development version), 'man 8 newhidups' is what you need to read carefully:

       vendor=regex
       product=regex
       serial=regex
       vendorid=regex
       productid=regex

Probably the only difference between these units (if they are all the
models) is the serial number. Running the driver in debug mode (with -DD
on the commandline) will help to find the serial number. Connect one UPS
at a time, so that you're able to unambiguously determine which one has
which serial number.
