What You Need to Do
To guard against ESD damage, take these precautions:
Electrostatic discharge can damage the components. Follow
these guidelines:
• 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 controller
• if available, use a static-safe work station
• when not in use, store each component in the anti-static
packaging in which it was shipped
To install the memory board, do these steps:
• Step 1: Verify that You Have All the Components
• Step 2: Remove the Controller from the Chassis
• Step 3: Remove the Side Plate of the Controller
• Step 4: Remove the Existing Memory Board (If Any)
• Step 5: Install the Memory Board
• Step 6: Replace the Side Plate
• Step 7: Attach Labels

WARNING
!
Step 2: Remove the Controller from the Chassis
You can install or remove a ControlLogix controller while chassis power is applied
and the system is operating. If you remove the controller, all the devices owned by
the controller go to their configured faulted state.
When you insert or remove a module while backplane power
is on, an electrical arc may occur. An electrical arc can cause
personal injury or property damage by:
• sending an erroneous signal to your system’s actuators
causing unintended machine motion or loss of
process control
• causing an explosion in a hazardous environment
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.
A. On the top and bottom of the controller, press the locking tabs.
B. Slide the controller out of the chassis.
