[Nut-upsuser] How do I initiate a shutdown sequence immediately after losing line power?

[Stoycho Ganev]

Using the upsrw command I was able to change the value of
battery.charge.low from 10 to 40, so my problem is solved for now (at
least temporarily, until I get my battery replaced). 

Thanks a lot for your help and have a nice day!
