Class B wiring Notes:
1. If no remote isolators or isolator bases are on the loops, device addressing can be assigned without concern for sequence.
2. If remote isolators or isolator bases are on the loops, the required addressing approach is to start at the output and assign each successive
isolator a higher address than the isolator it proceeds. For Class B wiring only, the “A” output and “B” output per loop are connected together
in parallel for wiring convenience.
