Push the handle up into the module’s front panel.  This will lock the module securely to the shelf.  Tighten the captive screw on 
the handle. 

7.

 

Repeat the above steps for each module being installed in the system. 

8.

 

After the modules are physically installed in the mounting shelf(s), they are ready for operation immediately after power is 
supplied to them. 

Note:

  It is recommended that the current limit point be checked whenever a rectifier is added to or removed from the power system.  Refer 

“Checking the ACU+ Current Limit Point after Adding or Removing a Rectifier Module or Converter Module” on page 18. 

Note:

  The rectifier or converter being added is assigned by the ACU+ the lowest available identification number.  If desired, you can change 

the identification number, see “Configuring the ACU+ Identification of Rectifiers” or “Configuring the ACU+ Identification of 
Converters” in the separate Power System Installation Manual (IM582127000).
