Notes

The positive and negative busbars mirror each other in terminal numbering. On the positive side, terminal numbers descend from MP6 at the top to MP1 at the bottom. On the negative side, terminal numbers ascend from MP1 at the top to MP6 at the bottom. All positive leads use red wiring and all negative leads use black wiring per standard convention.
