Warning: When you insert or remove the module while backplane power is on, an electrical arc
can occur. An electrical arc can cause personal injury or property damage by:
sending an erroneous signal to your system’s actuators causing unintended machine motion
or loss of process control
causing an explosion in a hazardous environment
Verify that power is removed or the area is non-hazardous before proceeding. Repeated electrical
arcing causes excessive wear to contacts on both the module and its mating connector. Worn
contacts may create electrical resistance that can affect module operation.
1 Align the module with the top and bottom guides, and then slide it into the
rack until the module is firmly against the backplane connector.
2 With a firm, steady push, snap the module into place.
3 Check that the holding clips on the top and bottom of the module are securely
in the locking holes of the rack.
4 Make a note of the slot location. You must identify the slot in which the
module is installed in order for the sample program to work correctly. Slot
numbers are identified on the green circuit board (backplane) of the
ControlLogix rack.
5 Turn power ON.
Note: If you insert the module improperly, the system may stop working, or may behave
unpredictably.
