Customer Interface Board Replacement
The DCB-L, DCB-M, and CIB are all connected together using solid
plug connections. This means that the best way to change any of the
boards without physically stressing the connections and boards is too
remove all 3 from the drive and change the board externally.
To replace the Customer Interface Board:
1. Record all drive setup information using any of the options
above, if possible.
2. Ensure that all medium voltage and control voltage power to the
drive is isolated and locked out.
3. Note and Mark the location and orientation of all the ribbon
cables, plugs, and connectors into the DCB-L, DCB-M, and CIB.
Use the electrical drawing as a reference.
4. Using your static strap, disconnect the Fiber Optic cables tie
wraps that run along the front of the cabinet from the sheet
metal. Use great care when handling Fiber Optic cables as any
damage can affect transmission capabilities.
5. Remove the Fiber Optic Interface (FOI) Boards from the DCBs.
There are pins from the DCB that slide into the FOI boards, but
they are physically attached using plastic connectors, and you
have to be firm, but CAREFUL, in freeing the FOI boards.
6. Carefully tie the FOI boards out of the way.
7. Remove the 10-mm taptites that are shown in the following
diagram. This will allow removal of the front piece of the sheet
metal frame around the low voltage control section, and grant
access to the plate on which the DCB-L, DCB-M, and CIB are
mounted.
8. This plate is held in the back using tabs, and held in the front
using taptites. Remove the taptites and remove the plate with the
boards still attached. Place the plate on a clean working surface.
9. There are numerous plastic clips holding all 3 boards to the plate.
Loosen the connectors and remove all 3 boards as one unit. If
you need to place the boards on a surface, ensure you have a
static pad to protect the boards.
10. Separate the boards and replace the existing CIB with the new
part. Verify the part number is the same, and note the revision
letters.
11. Follow Steps 9-3 in reverse to reinstall the boards back into the
low voltage control cabinet.
