Replacement Procedures
Converter Module Replacement
Converter modules can be inserted or removed with power applied
(hot swappable).
Note:
Each converter module locks into a module mounting shelf by
means of a latch located on the bottom of the module. The
latch and converter 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 2 .
DANGER! Take care when removing a converter module
that was in operation, as converter module surfaces
could be very hot.
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
Note:
Refer to Figure 2 as this procedure is performed.
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 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 2 .
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’s handle. Pull
the handle down out from the module’s front panel (this
will also retract the latch mechanism). See
Figure 2 .
6. Push the module completely into the shelf.
7. 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.
8. Certain functions (i.e. converter current limit, converter
addressing) may require adjustment when adding or
replacing a converter module. Refer to “Converter
Current Limit” on page 4 and the Power System
documentation for instructions.
9. After the converter modules are physically installed in the
mounting shelf(s), they are ready for operation
immediately after power is supplied to them. Verify that
the converters are operating normally.
10. Enable the external alarms, or notify appropriate
personnel that this procedure is finished.
11. Ensure that there are no local or remote alarms active on
the system.
