Configuring the ACU+ Identification of Rectifiers and Assigning Which Input Phase Is Connected to Each
Rectifier
When rectifiers are all installed prior to applying power and starting the system, the order in which the ACU+
identifies the rectifiers is by serial number (lowest serial number is Rect 1, next lowest is Rect 2, etc.). If you
prefer the ACU+ to identify the rectifiers by position in the system, perform the following procedure.
Upon power up, the ACU+ arbitrarily assigns Phase A, B, or C to each rectifier. This assignment is used to
display rectifier AC input phase voltage(s). The User may reassign the phase to each rectifier per your specific
installation by following the procedure below. (Note:
This power system is single phase only.)
Procedure

With the Main screen displayed, press ENT to go to the Main Menu. Navigate to and select “Settings”
(ENT).

down arrow key to move cursor down to the password line. Press ENT. “0” is highlighted. Press the up
arrow key once to change the “0” to”1” (default password is “1”), then press ENT twice. (

If you
