Installation Attaching Panel Circuit Modules
3.7.2 Mount Expander Boards
Expander Board Modules need to be mounted onto their respective modules (e.g. ICE-4 onto
ICM-4RK, or CRE-4 onto CRM-4RK) before being installed onto a chassis. To mount an expander
module:
1. Remove one module support screw and set it aside for later use.
2. Replace the module support screw with one module stand-off (supplied with expander).
3. Repeat Steps 1 and 2 for the three remaining module support screws. Remove only one at a
time so the panel circuit module does not come apart.
4. Insert pins on the front of the expander board into connector on the back of the module. Make
sure the pins are in line; then, press the two units together until they snap into place.
5. Install the four module support screws (removed earlier) through the back of the expander
board and into the stand-offs. Tighten securely.
Figure 3.7 illustrates the steps.
3.7.3 Installing a Multi-layer Module into the Chassis
Follow the instructions illustrated in Figure 3.8 to install a panel circuit module or a pair of loop
control/expander modules into into CHS-4N or CHS-M3.
1. Angle the module into the chassis so that the upper end of the rear board (or boards) fits into
the top slot.
2. Bring the module back down so that the lower board edges slip into the bottom slots.
3. Secure the module to the chassis with the two module screws. Tighten securely.
4. Connect the ribbon cable to the module.
