Cleaning Your cRIO-FRC and Installing Protective Gaskets 

 

This document describes how to clean the cRIO-FRC if it has been internally contaminated by metallic 
debris such as wire fragments, flakes, or dust. You must be very careful disassembling the cRIO-FRC. 
When you remove the printed circuit board (PCB) from the enclosure, it is vulnerable to electrostatic 
discharge (ESD) and physical damage. Failure to follow the directions in this document may result in 
damage to your cRIO-FRC and void the warranty. 

 
If you are uncomfortable with disassembling and cleaning your controller, you can provide a minimal 
level of protection by installing the external Module Connector Gasket. To do that, skip to the
