Notes:
L1, L2, L3 AC control power and A2, B2, C2 AC line output are phase sensitive, switching the order
of phases to any of the inputs may result in damage to the regen. L1 is the same phase as A1. L2
is the same phase as A2. L3 is the same phase as A3.
All power wire should be selected to match or exceed the voltage rating of the unit.
Field wiring for terminals will be copper 75
°
C wire only.
