General
NOTE!
For general operation instructions, refer to the NCU Controller User Manual (UM1M830BNA).
This system uses a special NCU configuration which allows intuitive naming of the bays and distribution
elements. The NCU User Manual documents the names found in a standard NCU configuration. This section
describes the differences in the NCU naming convention used in this special configuration as compared to a
standard NCU configuration.
NCU Numbering Scheme
The NCU identifies (numbers) the components of the system as detailed in Table 1.
