Install the Controller
Added Plug Attention Statement
Before you install the controller, make sure to see these ControlLogix® Chassis and 
Power Supply Installation Instructions:
• ControlLogix Chassis Installation Instructions, publication 1756-IN621
• ControlLogix Power Supply Installation Instructions, publication 1756-IN619
• ControlLogix Redundant Power Supply Installation Instructions, publication 
1756-IN620
When installing a GuardLogix controller, you can do the following:
• Place the controller in any slot. For SIL 3/PLe applications, install the 
safety partner in the slot immediately to the right of the primary controller.
• Use multiple controllers in the same chassis.
You can install or remove a GuardLogix controller while chassis power is on and 
the system is operating.
1. Align the circuit board with the top and bottom guides in the chassis.
2. Slide the module into the chassis until it snaps into place.
3. Verify that the controller is flush with the power supply or other installed 
modules.
4. For SIL 3/PLe applications, repeat steps 1...3 to install the safety partner in 
the slot immediately to the right of the primary controller.
ATTENTION: If you are using the controller to in a SIL 2/PLd 
application, you must use a Series C chassis.
NOTE: If operating above +55 °C (+131 °F) in a SIL 2/PLd 
application, modules greater than 6.2 W shall not be 
installed in slots adjacent to the controller.
ATTENTION: If you are using the controller in a SIL3/PLe 
application, you can use a Series B chassis (derating to 
+50 °C [+122 °F]) or Series C chassis with no restrictions.
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. 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.
ATTENTION: The GuardLogix 5580 controllers that are listed 
on page 1 of this document that end with a ‘K’ or are shipped 
with port protection plugs installed to provide a layer of 
protection from corrosive atmospheres. Port plugs must 
remain installed in unused ports at all times during storage 
and operation for the product to meet its corrosive 
atmosphere rating. If temporary access is required, plugs 
can be removed, and should be reinserted after temporary 
access is complete.

ATTENTION: This equipment is sensitive to electrostatic 
discharge, which can cause internal damage and affect 
normal operation. 
Follow these guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging 
when not in use.
