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.
