Replacement Procedures
Converter Module Replacement
The converter module is hot swappable. It can be removed and installed with the system operating.
WARNING!
To prevent damage to the latching mechanism, ensure the handle is in the open position
when installing or removing a converter module. NEVER hold the handle in the closed position when
installing a converter module into a shelf.
Procedure
1.
Performing this procedure may activate external alarms. Do one of the following. If possible, disable
these alarms. If these alarms cannot be easily disabled, notify the appropriate personnel to disregard
any alarms associated with this system while this procedure is performed.
2.
Loosen the captive screw that is located on the module handle. (Turn the fastener several turns
counterclockwise to loosen.) Pull the handle to pivot it out of the module front panel (this will also
retract the latch mechanism located at the right side of the module). Refer to
Figure 2
for latch
mechanism illustration.
3.
Grasp the handle and pull firmly to remove the module from the shelf.
4.
Place the replacement converter module into the mounting position without sliding it in completely.
5.
Loosen the captive screw on the module handle. Pull the handle to pivot it out of the module front panel
(this will also retract the latch mechanism located at the right side of the module). Refer to
Figure 2
for
latch mechanism illustration.
6.
Push the converter module completely into the shelf.
7.
Push the handle into the front panel of the module. Tighten the captive screw on the handle. This will
lock the module securely to the shelf.
8.
Certain functions (i.e. converter current limit, converter addressing) may require adjustment when
adding or replacing a converter module. Refer to the Power System documentation for instructions.
9.
Enable the external alarms, or notify appropriate personnel that this procedure is finished.
10.
Ensure that there are no local or remote alarms active on the system.
Converter Module Fan Replacement
Each converter module uses two fans for cooling. If fan replacement should become necessary, perform the
following procedure. It is recommended that both fans in the converter module be replaced at the same time.
Refer to
Figure 3
as this procedure is performed.
CAUTION!
In a system with NO redundant converter module, battery must have sufficient reserve to
power the load(s) while the converter module is removed for fan replacement.
NOTE!
When performing any step in this procedure that requires removal of existing hardware, retain all
hardware for use in subsequent steps.
