Install the Controller into the Chassis
When you install a ControlLogix controller, you can:
• place the controller in any slot
• use multiple controllers in the same chassis
You can install or remove a ControlLogix controller while chassis
power is on and the system is operating.
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 circuit board with the top and bottom guides in the
chassis.
2. Slide the module into the chassis. The controller is fully
installed when it is flush with the power supply or other
installed modules and the top and bottom latches are engaged.
!
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.
