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 to
remove all 3 from the drive and change the board externally.
Instructions 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. Loosen the two metal tabs on the top and bottom right of the
panel on which the SCB-L and SCB-M are mounted. The panel
is hinged on the right side, and should swing open to allow
access to the DCB-L, DCB-M and CIB boards. There is no need
to remove any connections from the SCB.
4. 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.
5. Using your static strap, disconnect the fiber optic cables from the
sheet metal by cutting the tie-wraps. The purpose is to create
enough slack to allow the FOI Boards to be moved slightly out
of the way, allowing access to remove the boards. Use great care
when handling Fiber Optics, as any damage can affect
transmission capabilities.
6. Remove the Fiber Optic Interface (FOI) Boards from the DCBs.
There are standoffs and pins from the DCB that slide into the
FOI boards, but they are physically attached only using the
standoff connectors, and you have to be firm, but CAREFUL, in
freeing the FOI boards.
7. 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.
8. Separate the boards and replace the damaged CIB with the new
part. Verify the part number is the same, and note the revision
letters.
9. Follow Steps 7-3 in reverse to re-install the boards back into the
low voltage control cabinet.
