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).
