That is correct but I found that most how tos for NUT were lacking some of the
details.  I found the NUT manual at
https://networkupstools.org/docs/user-manual.chunked/index.html.  I found I
needed to go through the entire chapter 6 of that manual to get things set up
correctly.  The end of chapter 6 describes how to set up multiple UPS
configurations.
