Remove the Controller from the Chassis, If Required
You can install or remove a ControlLogix controller while chassis
power is on and the system is operating. If you remove the controller,
all the devices owned by the controller go to their configured fault
state.
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. On the top and bottom of the controller, press the locking
tabs.
2. Slide the controller out of the chassis.
!
WARNING
When you insert or remove the module while
backplane power is on, an electrical arc can
occur. This could cause an explosion in
hazardous location installations. Be sure that
power is removed or the area is nonhazardous
before proceeding.
