Installation
ATTENTION: To avoid an electrical shock hazard assure that
all power to the controller has been removed prior to perform-
ing the following procedure.
!
ATTENTION: The controller contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing or
repairing this assembly. Component damage may result if ESD
control procedures are not followed. If you are not familiar
with static control procedures, reference A-B publication

Kit was received.
Components supplied:
(1) A Quad B Circuit Board and (1) plastic insulator
1. Ensure that all power has been removed to the controller.
2. Remove the front cover of the controller. Disconnect the ribbon cable
leading from the chassis to the top Logic Control Board of the
controller.
3. Remove the Logic Control Boards (2) by carefully squeezing the
standoffs between the bottom board and chassis.
4. Remove the ribbon cable connecting the top and bottom Logic Control
Boards.
5. Separate the two boards by unscrewing the standoffs. The standoffs
should remain in the bottom board.
6. Position the A Quad B Board with the foil side up. Lay the supplied
insulator on the foil side of the A Quad B Board.
7. Carefully snap the top Logic Control Board to the A Quad B Board.
The foil sides of the boards must face one another. Assure that the
insulator is still in place.
8. Align the pins on the A Quad B Board with the socket on the bottom
Logic Control Board. Snap the boards together. Reconnect the ribbon
cable previously removed in step 4.
9. Mount the completed board assembly back on the chassis.
10. Reconnect the ribbon cable previously removed in step 2.
