Perform steps in the Systems Operation, Testing and Adjusting, "Internal Component Preremoval Steps (Controls Cabinet)" in order to de-energize the system and gain access to internal components.
Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. When not in use, keep the module in its static-shield bag. Follow these guidelines when you handle any module:Touch a grounded object to discharge static potential.Wear an approved wrist-strap grounding device.Do not touch the bus connector or connector pins.Do not touch circuit components inside the module.If available, use a static-safe work station.

Disconnect all connectors from the board.Refer to Illustration 2.
Remove the two cross head screw (ground) from the top and bottom of the board.
Disconnect the four white plastic standoffs connecting the board to the left panel using the following method.Note: The board must be removed from the stand-offs without bending the board.
Pinch the head of each stand-off so that the board is not locked to the stand-off but is still attached to the stand-off.
Remove the board by gently and evenly pulling the board from all stand-offs at the same time.Installation

Position the board in the cabinet over the four white stand-offs that are connected to the left panel.
Push the board, gently and evenly, onto all the stand-offs simultaneously. Make sure all stand-offs are locked in place.
Attach the two cross head screws (ground) to the top and bottom screw holes in the middle of the board (J2 and J3).
Plug the wire connectors into the correct connectors on the board. Check the labels on each connector for proper placement.Refer to Illustration 2.
