Maximum Demands of Total Power (Points 15 - 19)
These points are formatted as 2's complement fractions. They represent a fraction of
4500W Secondary in normal operation, or 3000W Secondary in Open Delta operation.
Inputs above/below +/-4500 or +/-3000W Secondary are pinned at +/-4500 or +/-
3000W Secondary, respectively.
Phase Angle (Points 20 - 25)
These points are formatted as 2's complement integers. They represent angles from -
180.00 (0x0F8F8) to +180.00 (0x00708).
