The Eaton 5P 850G and the 5P 1000 have the option "Auto start delay":

  Load segments - Auto start delay [No Delay] [1 s] [2 s]…[65354 s]
  The connected load is powered after the specified delay.
  Defaults: Group 1: 3 s  Group 2: 6 s

Maybe it's the difference between the "E" equipment and the "P" stuff. See 

The noise level is given as < 40 dBA so maybe it has a fan running permanently. 
Eaton's Automatic Voltage Regulation can be noisy.
