Figure Notes:
1. Maximum allowed NAC current consumption (aux power plus NACs): 9A (Special Application) or 4A regulated 24V dc.
2. Maximum per NAC: 3 A
3. Maximum allowed auxiliary power current consumption: 5A (total supply).
4. Maximum per auxiliary output: 2 A
5. Class A wiring is possible only if a 4090-9117 Power Isolator is used.
6. International systems require ferrite beads. Use kit 4100-5129.
