I understand now. Not sure why a UPS has a 'shutdown' feature, but, it
can't be shutdown before the machine has completed its shutdown. Is this
why the UPS has the variable, ups.delay.shutdown ? Mine is set to 20. I
assume units are seconds. Do I adjust it to account for the time my
machine takes to shutdown?
