To increase system current capacity, a rectifier module can easily be added to an existing
rectifier module mounting shelf Spec. No. 588705000 that contains an empty rectifier

It is recommended that the current limit point be checked whenever a rectifier module 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 module being added is assigned by the ACU+ the lowest available
