Configuring the NCU Identification of Rectifiers and
Assigning which Input Feed is Connected to the Rectifiers
When rectifiers are all installed prior to applying power and starting the system, the order in which the NCU identifies the rectifiers is
by serial number (lowest serial number is Rect 1, next lowest is Rect 2, etc.). If you prefer the NCU to identify the rectifiers by position
in the system, perform the following procedure.
Upon power up, the NCU arbitrarily assigns Feed AC1, AC2, or AC3 to each rectifier. This assignment is used to display rectifier AC
input feed voltage(s). The User may reassign the feed to each rectifier per your specific installation by following the procedure below.

Configuring the NCU Identification of Solar Converters
When solar converters are all installed prior to applying power and starting the system, the order in which the NCU identifies the solar
converters is by serial number (lowest serial number is Solar Conv 1, next lowest is Solar Conv 2, etc.). If you prefer the NCU to identify
the solar converters by position in the system, perform the following procedure.
