Note that the load.off delay is specified in seconds, but internally it
is divided by 60, using integer division, to get the number of minutes.
I said the following in a prior message about a different Cyber Power
UPS model:

==When I specify a 59 second delay on the command line, the UPS shuts off
immediately.

  59 second delay specified - immediate shutoff
  60 second delay specified - exactly one minute delay, then shutoff
  80 second delay specified - exactly one minute delay, then shutoff
 115 second delay specified - exactly one minute delay, then shutoff
 128 second delay specified - exactly two minute delay, then shutoff

So if I had to guess, I would offer that the UPS is doing an integer
divide by 60 on the number of seconds given by the command.  That is why
the request for a 59 second delay resulted in no delay at all.

I see the same behavior with this model.
