I am a little confused by this post, but I think ultimately you are looking to monitor this UPS device. If that is correct, then what we need to figure out is, what objects the device supports and then of those objects, which ones you care to monitor.
I would recommend starting off with an SNMP Walk on the device using the WUG tool in the web interface. You should start the walk with this OID:
That is the top level Emerson OID, so starting the walk there will only return objects within the Emerson tree. If you save the results of the walk to a file and post it, I would be happy to take a look at it with you.
