Installing Rectifier or Converter Modules into
Spec. No. 588705000 Module Mounting Shelves
Rectifier or converter modules are installed in a 588705000 module mounting shelf, depending on the shelf ordered.
•
Rectifiers are installed in 588705000 List 21, List 22, 31, and 32 shelves.
•
Converters are installed in 588705000 List 40, List 41, and 42 shelves.
Rectifier or converter modules can be inserted or removed with power applied (hot swappable).
Note:
The rectifier or converter module locks into the module mounting shelf through a latch located on the underside of the module. The
latch and module handle are interactive. Push the handle into the module's front panel, and the latch will pop out from the module
bottom. Click the handle to pop it out from the module's front panel, and the latch will retract back into the module. The latch

hand side of the shelf. The second three-phase input feeds the modules on the right-hand side. To maintain phase balance, install
rectifier modules in groups of three; that is, fill all three mounting positions on the left and/or all three on the right.
PROCEDURE
1.
Unpack the rectifier or converter modules.
2.
If present, remove blank cover panels from the module mounting positions into which modules are to be installed.
3.
Place the module into an unoccupied mounting slot without sliding it in completely.
4.
Click the module handle in order to pop it forwards out of the module's front panel (this will also retract the latch mechanism
located on the underside of the module).
5.
Push the module completely into the shelf.
6.
Push the handle into the front panel of the module. This will make the latch lock the module securely to the shelf.
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.
