Rectifier Module Replacement

Rectifier modules can be inserted or removed with power applied (hot swappable).
NOTE! Each rectifier module locks into a module mounting shelf by means of a latch located
on the bottom of the module. The latch and rectifier 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 6.
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 module. NEVER hold the handle in the closed
position when installing a rectifier module into a shelf.
Procedure
NOTE! Refer to Figure 6 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 Error! Reference source not found..
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.
