Unpacking the PDCA
At least one Power Distribution Control Assembly (PDCA) is shipped with the Superdome. In some cases, the
customer may have ordered two PDCAs, the second to be used as a backup power source. Unpack the PDCA
now and ensure it has the power power cord option for your installation.
Currently there are several power cord options available for the PDCAs. These are shown in Table 2-1. Only
options 6 and 7 are currently available in new superdome configurations. The other options shown in
Table 2-1 are obsolete but are given in case you encounter a Superdome with obsolete power cord options.
Table 2-2 details options 4 through 7.
