The SPS can connect to auxiliary power appliances via the dedicated auxiliary power tap (TB3). If more power is needed, any of the three
NAC outputs can be used for auxiliary power.
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.
