I just looked up the manual for the meter and according the the documentation the "D7" error/diagnostic code means the following:
"23.6.7 Diagnostic D7 (Energy Polarity Check) The D7 diagnostic checks for reverse energy flow of one or more phases. If the energy polarity (watts) for any phase is negative, this flag is tripped. This check is not performed if phase A voltage is missing."
Another thing that is odd is the meter is reading an input voltage of 120. This should be 480vac.
