Adding a Rectifier or Converter Module to an Existing
Module Mounting Shelf Spec. No. 588705000
To increase system current capacity, a rectifier or converter
module can easily be added to an existing module mounting shelf
Spec. No. 588705000 that contains an empty rectifier or converter
module mounting position.
It is recommended that the current limit point be checked
whenever a rectifier or converter module is added to or removed
from a 588705000 shelf in the power system. Refer to “Checking
the ACU+ Current Limit Point after Adding or Removing a Rectifier
Module or Converter Module” on page 18.
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 Rectifiers” or “Configuring the ACU+ Identification
of Converters” in the separate Power System Installation
Instructions (IM582127000).
•
For rectifier module installation instructions, refer to
Rectifier Instructions (UM1R483500E).
•
For converter module installation instructions, refer to
Converter Instructions (UM1C400483500E).
Adding a Rectifier or Converter Module to an Existing
Module Mounting Shelf Spec. No. 588705300
To increase system current capacity, a rectifier module can easily
be added to an existing module mounting shelf Spec. No.
588705300 that contains an empty rectifier module mounting
position. Likewise, to increase subsystem capacity a DC-DC
converter module can be added to a module mounting shelf Spec.
No. 588705300 that contains an empty converter module
mounting position.
Rectifier and converter modules can be inserted or removed with
power applied (hot swappable).
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
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
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
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
5.
Push the module completely into the shelf.
