Class B NAC wiring
To connect the XPS to appliances using Class B wiring, read the following instructions and refer to Figure 12.
1. Use NAC1, NAC2, or NAC3 to route wire (between 12 [3.309 mm²] and 18 AWG [0.8231 mm²]) from B+ and B- on the XPS to the first appliance.
2. Route wire to the next appliance as shown in the figure. Repeat for each appliance.
3. Route wire from the last appliance to the EOLR harness (10k ohm, 1/2 W: P/N 733-894, PID# 4081-9008).
4. Repeat steps 1 through 3 for each NAC output you want to use.
5. Leave the 10k, 1/2 W, brown/black/orange resistor (378-030) on each unused circuit. The circuit must connect B+ to B- terminals.
