Replacement Procedures
Rectifier Replacement
The rectifier is hot swappable. It can be removed and installed with the system operating.
NOTE!
Each rectifier locks into a module mounting shelf by means of a latch located on the bottom of
the module. The latch and rectifier 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 16
.
DANGER! Take care when removing a rectifier that was in operation, as rectifier 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 module. NEVER hold the handle in the closed position when installing a
module into a shelf.
Procedure
NOTE!
Refer to
Figure 16
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. On the rectifier to be removed, click the rectifier’s handle in order to pop it forward out of the rectifier's
front panel. This will retract the latch mechanism located on the underside of the rectifier and thus
unlock the rectifier from the shelf. Refer to Figure 16 for latch mechanism illustration.
3. Slide the rectifier out by pulling forward.
4. Place the replacement rectifier into the mounting slot without sliding it in completely.
5. On the replacement rectifier, click the rectifier’s handle in order to pop it forward out of the rectifier's
front panel (this will also retract the latch mechanism located on the underside of the rectifier).
6. Push the rectifier completely into the shelf.
7. Push the handle into the front panel of the rectifier. This locks the rectifier securely to the shelf.
8. Certain functions (i.e. rectifier current limit, rectifier addressing) may require adjustment when adding or
replacing a rectifier Module. 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.
