I had the same problem with an Eaton Ellipse ECO 1500. 
ups.delay.shutdown got lost at each power cycle.  I fixed it by setting

      offdelay = 30
      ondelay = 40

in ups.conf.  This seems to me to be a better solution than writing a 
script.  I'm guessing that if these two lines are omitted, no value is 
sent to the UPS unit.  Is this true?
