ADDING A RECTIFIER OR DC-DC CONVERTER MODULE
TO AN EXISTING MODULE MOUNTING ASSEMBLY
To increase system current capacity, a rectifier module can easily be added to an existing
module mounting assembly that contains an empty rectifier module mounting position.
Likewise, in systems that accept DC-DC converter modules, to increase subsystem
capacity a DC-DC converter module can be added to a module mounting assembly that
contains an empty converter module mounting position.
The module location diagram on the front of each module mounting assembly shows
which type of module can be operated in that shelf. (See Figure 3-1.) Rectifier modules
will operate in any mounting position in any shelf. If a shelf accepts DC-DC converter
modules, they must be installed in any or all of the four middle mounting positions (B, C,
F, G) of each 8-position module mounting shelf.
It is recommended that the current limit point be checked whenever a rectifier is added to
or removed from the power system. Refer to “Checking the ACU+ Current Limit Point
after Adding or Removing a Rectifier” in “CHAPTER 4. TROUBLESHOOTING AND
REPAIR”.
The rectifier or converter module 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 Rectifier Modules” or “Configuring the ACU+
Identification of Converter Modules” in Chapter 5 of the separate Power System
Installation Manual (IM581127000).
