Replacement Procedures
Rectifier Module Replacement
DANGER! Take care when removing a rectifier module that was in operation, as rectifier 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 rectifier. NEVER hold the handle in the closed position when installing a
rectifier into a shelf.
The rectifier is hot swappable. It can be removed and installed with the system operating.
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 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.
3. Grasp the handle and pull firmly to remove the module from the shelf.
4. Place the replacement Rectifier 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 rectifier 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. rectifier current limit, rectifier addressing) may require adjustment when adding or
replacing a rectifier. Refer to the Power System documentation for instructions.
9. After the Rectifiers are physically installed in the mounting shelf(s), they are ready for operation
immediately after power is supplied to them. Verify that the Rectifiers 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.
