NOTE: A qualified electrician must wire the PDCA receptacle to site power using copper wire and in compliance with all local codes. All branch circuits used within a complex must be connected together to form a common ground. All power sources such as transformers, UPSs, and other sources, must be connected together to form a common ground. When only one PDCA is installed in a system cabinet, it must be installed as PDCA 0. For the location of PDCA 0, see Figure 1-1. NOTE: When wiring a PDCA, phase rotation is unimportant. When using two PDCAs, however, the rotation must be consistent for both. Figure 1-1 PDCA Locations PDCA 1 PDCA 0 System Power Requirements Table 1-8 and Table 1-9 list the ac power requirements for an HP Integrity Superdome/sx2000 system. These tables provide information to help determine the amount of ac power needed for your computer room.
