To install wiring to connections:
1. If not already open, open the front door (see Figure 13 ) by lifting the latch from the bottom and turning to
the right (counterclockwise) and swing the door open.
2. Loosen the screws securing the inside distribution panel door and swing the door open.
3. Loosen the screws securing the inside trim plate(s) and remove the plate(s). Retain trim plate(s) and
hardware for later use.
4. If wiring an IAC-D with distribution panels, continue to Step 5 ; if wiring an IAC-D with subfeed breakers or
an output breaker, skip to Step 8 .
5. Install customer-supplied branch circuit breakers into the distribution panel (see Figure 22 or Figure 23 ).
Use Cutler-Hammer bolt-on type BAB or QBHW breakers.
NOTE When wiring branch circuits, begin adding conduits at the back of the bottom or top
conduit landing plates to simplify future circuit additions.
6. Route output cables to the branch circuit breakers and wire the branch circuits according to the branch
circuit breaker manufacturer's ratings and instructions, and national and local electrical codes (input is
prewired to the panelboard). See
Figure 22 or Figure 23 for neutral and ground terminal locations. See
paragraph 3.2.2 IAC-D Power Wiring Preparation , Table 6 or Table 7 , and Table 10 for IAC-D wiring and
termination requirements.
7. If wiring an IAC-D with subfeed breakers or an output breaker, continue to Step 8 ; otherwise, skip to
Step 11 .
NOTE When wiring subfeed branch circuits, begin adding conduits at the back of the bottom or
top conduit landing plates to simplify future circuit additions.
8. Route output cables from subfeed breaker terminal blocks or output breaker to the critical load. See
Figure 23 , Figure 25 , or Figure 27 for IAC-D output, neutral, and ground terminal locations. See paragraph
3.2.2 IAC-D Power Wiring Preparation , Table 6 or Table 7 , and Table 10 for IAC-D wiring and termination
requirements.
9. Connect Ground, phase A, B, and C, and Neutral power wiring to the subfeed breaker terminal blocks or
output breaker and the critical load.
For a detailed view of the IAC-D output terminals, see Figure 24 , Figure 26 , or Figure 28 .
