HP Integrity Superdome and 9000 Superdome sx2000 manual System Power Requirements

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.
