Rectifiers modules can be installed in any mounting position of each module mounting
shelf. Converters modules can be installed in any of the three far right mounting
positions of each module mounting shelf (as viewed from the front). See Figure 3-1.
Note: Each rectifier and converter module locks into the module mounting shelf by
means of a latch located on the bottom of the module. The latch and module
handle are interactive. Pushing the handle up into the module’s front panel
causes the latch to extend to the locking position; pulling the handle down out
from the module’s front panel causes the latch to retract. See Figure 3-1.
Warning: To prevent damage to the latching mechanism, ensure the handle is in
the open position when installing or removing a module. NEVER hold
the handle in the closed position when installing a module into a shelf.
Procedure
1) Unpack the modules.
2) Note the model number located on the front of each module. Model numbers
starting with the letter “R” are rectifier modules. Model numbers starting with the
letter “C” are converter modules.
3) Place the module into an unoccupied mounting position without sliding it in
completely. Rectifiers modules can be installed in any mounting position of each
module mounting shelf. Converters modules can be installed in any of the three
far right mounting positions of each module mounting shelf (as viewed from the
front). See Figure 3-1.
4) Loosen the captive screw on the module’s handle. Pull the handle down out from
the module’s front panel (this will also retract the latch mechanism). See Figure
3-1.
5) Push the module completely into the shelf.
6) 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 to “Checking the ACU+
Current Limit Point after Adding or Removing a Rectifier” in “CHAPTER 4.
TROUBLESHOOTING AND REPAIR”.
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 Chapter 5 of the
separate Power System Installation Manual (IM582127000).
