    and 15.):
    Case 1: On/Off Input Is Set for Unit On and
    then Input Power Is Applied (delay from
    point at which VI = VI, min until VO = 10% of
    VO, nom).
    Case 2: Input Power Is Applied for at Least
    One Second, and then the On/Off Input Is
    Set to Turn the Module On (delay from point
    at which on/off input is toggled until
    VO = 10% of VO, nom).
