NAC Circuit Wiring
The FX-3500 supports up to 4 NAC circuits that can be wired as either:
•
Class B (Style Y)
•
Class A (Style Z)
To supervise each Class B NAC circuit, use a 3.9K End-of-Line resistor.
Each NAC circuit provides up to 1.5A, total 6A of current maximum if no auxiliary power is
used.
For detailed wiring diagrams see Figure 21 NAC Circuit – Class B (Style Y) Wiring or Figure 22
NAC Circuit – Class A (Style Z) Wiring.
