Main Pcb; Wiring Diagram - Fellowes Powershred Series Technical & Service Manual

Main PC Board
•
The main PC board is located at the right, front of the cabinet shelf
•
The PCB slides onto a support that is attached to the cabinet shelf
•
The wires leading to capacitor are hard-wired to the PCB
•
Other wires (i.e., bin full sensor and motor wires; control panel cable) can be disconnected
from the board via quick disconnect
•
If a component that is hard-wired to the main PC board fails, the entire PC board must be
replaced (NOTE: Splicing is NOT an acceptable form of repair)
Before replacing the PC board, disconnect the wires (that are not hard-wired) from the PC board.
CAUTION! Do not reverse the wires on the PC board. Make notes and tag wires as you remove
them from the board. See the wiring diagram. Do not break the hard wired connections if the
board is not being replaced.
To replace the main PC board:
1. Disconnect the power wires from the disconnect switch and the power receptacle. (See
wiring diagram on pg22.)
2. Disconnect the 3 motor wires from the main PC board.
3. Disconnect the black and blue wire tabs from the capacitor.
4. Disconnect the bin full PC board cable connector from the PC board.
5. Disconnect the door open switch wires.
6. Remove the plastic wire crimps that hold the PC board to the support. Lift the PC board out
of the support.
7. Slide the new PC board into the support and secure with wire crimps.
8. Connect all of the wires from the various sensors and components to the new PC board.
