2 of the 3 phases on my PAN-42 are showing reflected/mirrored power factors. How is that possible?

If the phases are not aligned in the installation, the power factor data lines will look like they are reflections of each other (mirror).

To fix this, confirm the right phases are installed in that L1 and I1+/- are matching in their wire position and so on for the remaining phases. When looking at the front of a PAN-42, the voltage inputs are installed on the left hand side from top to bottom while the current inputs are installed on the right hand side from bottom to top.
