2.5.1 Installing the Module in the Rack
You can install or remove ControlLogix system components while chassis power
is applied and the system is operating. However, please note the following
warning.
Warning: When you insert or remove the module while backplane power is on, an electrical arc
can cause personal injury or property damage by sending an erroneous signal to your system's
actuators. This can cause unintended machine motion or loss of process control. Electrical arcs
may also cause an explosion they occur in a hazardous environment. Verify that power is
removed, or that the area is non-hazardous before proceeding. Repeated electrical arching
causes excessive wear to contacts on both the module and its mating connector. Worn contacts
may create electrical resistance that can affect module operation.
Align the module with the top and bottom guides, and then slide it into the rack
until the module is firmly seated against the backplane connector.
With a firm, steady push, snap the module into place. Ensure that the holding
clips on the top and bottom of the module are securely in the locking holes of the
rack.
Make a note of the slot location. Slot numbers are identified on the green circuit
board (backplane) of the ControlLogix rack.
Turn power On.
