Replacement Procedures
Rectifier Replacement
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 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
NOTE!
Refer to
Figure 11
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, loosen the captive fastener securing the top of the latch mechanism to
the front of the rectifier. Pull the top of the latch mechanism away from the rectifier (this will retract the
latch mechanism located on the underside of the rectifier). This unlocks the rectifier from the shelf.
Refer to
Figure 11 for latch mechanism illustration.
3. Slide the rectifier out by pulling forwards.
4. Place the replacement rectifier into the mounting position without sliding it in completely.
5. On the replacement rectifier, loosen the captive fastener securing the top of the latch mechanism to the
front of the rectifier. Pull the top of the latch mechanism away from the rectifier (this will retract the
latch mechanism located on the underside of the rectifier). See
Figure 11 .
6. Push the rectifier completely into the shelf.
7. Push the top of the latch mechanism into the front panel of the rectifier, and secure by tightening the
captive fastener. 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. 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.
