9.
Disconnect two (2) cables from the interface circuit card.
10.
Remove the one screw that secures the circuit card. Carefully lift the circuit card from its mounting
posts, and remove.
11.
Place the circuit card over its mounting posts and carefully press down at each post until fully seated.
Install and tighten the one mounting screw.
12.
Connect the two cables previously disconnected.
13.
Install the top/rear cover on the Mounting Frame, and secure with the nine previously removed screws.
14.
Remove the grounding wrist strap.
NOTE!
In the next step, the Retrofit Mounting Frame CANNOT be installed in the Power Bay unless all
Rectifiers are first removed from the Mounting Frame. Doing so will defeat the precharge circuit in the
rectifiers and cause arching and pitting on the DC power connector!
15.
Slide the Mounting Frame into its mounting position in the Power Bay. Secure with the four previously
removed screws.
16.
Install the three Rectifiers into the Mounting Frame. Refer to the previous procedure, “Replacing a
Rectifier”, for step-by-step instructions.
17.
After the Rectifiers are physically installed in the Mounting Frame, they are ready for operation
immediately after power is supplied to them. Verify that the Rectifiers are operating normally.
18.
On the Power System controller (MCA), update the system inventory as necessary. Refer to the Power
System documentation for a procedure.
19.
Ensure that there are no local or remote alarms active on the system.
20.
Install the front cover on the Mounting Frame, and secure by tightening the two captive fasteners.
Replacing a Fan in a Rectifier
Each Rectifier in a Mounting Frame uses a fan for cooling. If fan replacement should become necessary,
perform the following procedure.
Refer to
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.
