Why when using ATV66U41N4 drive on a demo unit does the drive when powered up can make changes to the programming and when powered down and then back up it will go back to factory defaults?

When drive is used as a demo unit and only applying single phase power it can cause the drive to go back to factory defaults every time it is powered down and then back up if the proper steps haven`t been taken.
The first time the drive is powered up need to have CL1 and CL2 power only, make programming changes and power down, then connect L1 and L2 and the drive should power up and retain the settings thereafter.
