Thanks for the pointer to the Slackware-specific scripts - that is helpful.
/usr/libexec/nut/nut_kill_inverter calls "/etc/rc.d/rc.ups shutdown", which calls "upsdrvctl shutdown". So that part seems reasonable.
If you can power the system from a different UPS or outlet, you can plug a dummy load (like a lamp) into this UPS, and invoke the driver shutdown command directly. This will allow you to see the debug messages.
It will be something like the following:
service stop nut # (or equivalent)
/usr/libexec/nut/usbhid-ups -a Eaton5E650iUSB -DD -k

When you say it seems to hang, is this including the 40 and 10 second sleep commands in nut_kill_inverter?

It looks like the driver recognized the "offdelay" parameter, but there should be a matching "ups.delay.start" variable to match the "ondelay" parameter.
I don't know much about this specific model, so I have CC'd Arnaud at Eaton.
