1. Ensure there is no power to the equipment.
To prevent electrical shock, ensure the main power has
been disconnected before working on the sensing board.
Verify that all circuits are voltage free using a hot stick
or appropriate high voltage-measuring defice. Failure to
do so may result in injury or death.
2. Mark the position of the ribbon cable and wires.
3. Remove the screws and lift the ring lugs from the terminals to remove
the wires.
4. Release the locking mechanism located on each side of the ribbon
cable connector and pull the ribbon cable straight out to prevent
bending the pins.
5. Remove the 4 nuts that secure the assembly to the side panel.
6. Replace with the new assembly securing with all 4 nuts and washers.
(See diagram below)
7. Replace ring lugs on terminals. Plug in ribbon cable making sure that
it is positioned properly and fitting is secure (locking mechanism is
engaged).
8. For personnel and equipment safety, ensure both grounding
connections are reconnected to the sensing board.
