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 2-1.
NOTE: When wiring a PDCA, phase rotation is unimportant. When using two PDCAs, however,
the rotation must be consistent for both.

System Power Requirements
Table 2-8 and Table 2-9 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.
