InstallationEaton 93PM Integrated Accessory Cabinet-Distribution (50–200 kW) Installation and Operation Manual P-164000229—Rev 6 www.eaton.com/powerquality 4-15Figure 4-9. 480 VAC Input to IAC-D from UPS Terminal Detail – 208V/208V4.3.3 50 kW and 100 kW Output WiringTo install wiring to connections:1. If not already open, open the front door (see Figure 4-1) by lifting the latch from the bottom and turning tothe 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) andhardware for later use.4. If wiring an IAC-D with distribution panels, continue to Step 5; if wiring an IAC-D with subfeed breakers oran output breaker, skip to Step 8.5. Install customer-supplied branch circuit breakers into the distribution panel (see Figure 4-10 orFigure 4-11). Use Cutler-Hammer bolt-on type BAB or QBHW breakers.6. Route output cables to the branch circuit breakers and wire the branch circuits according to the branchcircuit breaker manufacturer's ratings and instructions, and national and local electrical codes (input isprewired to the panelboard). See Figure 4-10 or Figure 4-11 for neutral and ground terminal locations. Seeparagraph 3.2.2, Table 3-6 or Table 3-7, and Table 3-10 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 toStep 11.8. Route output cables from subfeed breaker terminal blocks or output breaker to the critical load. SeeFigure 4-11, Figure 4-13, or Figure 4-15 for IAC-D output, neutral, and ground terminal locations. Seeparagraph 3.2.2, Table 3-6 or Table 3-7, and Table 3-10 for IAC-D wiring and termination requirements.NOTE When wiring branch circuits, begin adding conduits at the back of the bottom or topconduit landing plates to simplify future circuit additions.NOTE When wiring subfeed branch circuits, begin adding conduits at the back of thebottom or top conduit landing plates to simplify future circuit additions.Phase APhase CPhase B480 VAC Input to IAC-D
