Notes:
1. All output signals on ACH7 are multiplexed.
2. All output voltages on A33 J2 are referenced to ground (J2-15 and J2-16).
3. Must have L1, L2, L3, CT21, CT22, and CT23 for these phase angle outputs.
4. J1-24 (5VDC), J1-23 (signal), J1-18 (return).
5. Must have L1, L2, L3, Bus L1, Bus L2, and Bus L3 for these outputs.
6. L1, L2, and L3 can be 0 to 180out of phase with Bus L1, Bus L2, and Bus L3, respectively.
