How do you derate the Altivar ATV56 drive for installation at 5000 feet above see level?

Above 3300 feet, must derate 1.2% for every 300 feet up to 6600 feet. This means {[(5000 - 3300)/( 300)] x 0.012} = 0.068 or derate current by 6.8%. i.e. the usable current of the drive is 93.2 % of the drives rating.
