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.
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.
3. Align the circuit board with the top
and bottom guides in the chassis.
4. Slide the module into the chassis. Make sure it is flush with the power supply
or other modules and the top and bottom latches are engaged.
2. Turn the key to the PROG position.
1. Insert the key into the
controller.
