ondelay maps to ups.delay.start, and offdelay maps to ups.delay.shutdown.

offdelay needs to be greater than ondelay. I'm using 600 & 615 on a 
Win2k3 server I have connected to an Evolution 850. If the power comes 
back on during the offdelay period, the ups will do a reboot cycle with 
a 15s wait.

If the power is off for more than offdelay, yeah, it will turn on 
instantly (*), but by then the PC has had no power for at least 15s.

The above will depend on having a good UPS.

(*) Some UPS's do provide extra options to determine when they will 
restore power to load.
