Notes
1. 110/120 VAC system is not supported
2. See Table A-7: PDU plugs, circuit breakers, and receptacles on page A-7 for
information about poles and current.
3. The total power consumption of the system is the same whether it uses single
phase or three phase power. The difference is that each branch of the three phase
input power draws less current than the single phase conductors.
