5.2.3 Replacing a Fan in a Rectifier
Each Rectifier in a Mounting Frame uses two fans for cooling. If fan replacement should become necessary, perform the following
procedure. It is recommended that both fans in the Rectifier be replaced at the same time.
Refer to Figure 5.2 as this procedure is performed.
CAUTION! In a system with NO redundant Rectifier, battery must have sufficient reserve to power the load(s) while the
Rectifier is removed for fan replacement.
WARNING! Circuit cards used in this equipment contain static-sensitive devices. Read the Static Warning page at the front
of this document before performing the following procedure.
NOTE!
When performing any step in this procedure that requires removal of existing hardware, retain all hardware for use in
subsequent steps.
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 future alarms associated with this system
while this procedure is being performed.
2. Remove the Rectifier from the Mounting Frame. Refer to a previous procedure, “Replacing a Rectifier”, for step-by-step
instructions.
3. Place the Rectifier on a static-safe work surface. Connect an approved grounding strap to your wrist for the remainder of this
procedure.
4. Remove the five (5) faceplate mounting screws shown in Figure 5.2 from the Rectifier. Remove the faceplate.
5. Carefully pull the fan(s) out from the Rectifier chassis, until the fan power cable(s) can be accessed.
6. Unplug the fan power cable(s) from connector(s) on the PC board, and remove the fan(s).
7. Plug the power cable(s) of the replacement fan(s) into the connector(s) on the PC board.
8. Place each fan in its cavity in the Rectifier chassis, orienting the fan so that:
a) The arrow on the fan body points toward the rear of the Rectifier, and
b) The power cable exits the fan body toward the other fan, as shown in Figure 5.2.
9. Reinstall the faceplate on the Rectifier chassis. Ensure that no fan wiring is pinched. Secure faceplate with the five (5)
previously removed screws.
10. Reinstall the Rectifier into the Mounting Frame. Refer to a previous procedure, “Replacing a Rectifier”.
11. When the fans start, check to ensure that each is providing front-to-back airflow. If air direction is wrong, immediately
remove the Rectifier from the Mounting Frame. Repeat previous steps to check fan orientation, and correct as necessary.
Reinstall the Rectifier and again check for proper airflow.
12. Enable the external alarms, or notify appropriate personnel that this procedure is finished.
13. Ensure that there are no local or remote alarms active on the system.
