Figure 4-3. Removing the Relay Modules From the Housing.

Removing the basic module:

Loosen the module by pulling the top and bottom releasing levers to the left. Grasp the module by the edges of the front panel and pull it out of the housing. Place the module on a conductive surface.

Take all necessary precautions to avoid electrostatic discharges into or around the module.

Removing the additional I/O module:

Remove the basic module using the procedure described above.

Grasp the additional I/O module behind the rear edges of the printed circuit boards on the left side of the module and pull it out of the housing.

Inserting the additional I/O module:

Ensure that the printed circuit board edges are properly positioned to enter the guide slots.

Push the module into the housing as far as it will go. Ensure that the internal connector is properly engaged.
