3. FIELD REPLACEABLE UNITS (FRUS)
Each FRUS comes with detail instructions of how the part should be performed. At the ends of most wires/cables are
labels that indicates their locations. When ordering replacement parts from the factory, supply the information from the
System Label (refer to Technical Assistance section in this manual). Include the model number, serial number, input/
output voltages, and power rating when ordering parts. Replacement parts must be replaced by qualied factory trained
service personnel only.
3.1. MOTHER/MAIN BOARDS
The Mother/Main Boards are located on the three middle shelves and mounted with 10 screws. Verify that all connectors
are matches with their designations and pins #1, 2, etc (Note: all plugs and connections are not used!) Unplug jumper on
daughter board and all connectors from on Mother Board. Install the new board. Reconnect all plugs and connections
returning them to their original orientations.
Note: all plugs and connections are not used!
Circuit boards and IGBTs contain ESDS (Electro-Static Discharge Sus-
ceptible) components. Handle and package ESDS devices in accordance
handling the devices and circuit boards. Always package components
-
tive material that the FRUS came in before transporting (Even if a device
has failed). Failure to do so could result in further damage, complicating
repair and failure analysis.
3.2. All Other Parts
Verify that the cables are marked before disconnecting. Replace the defective part with the new part. Reconnect wiring
the same way as it was disconnected.
