Handling components
Warning
The Industrial PC contains electronic components with highly integrated modules or
modular elements. Due to the technology employed, these electronic components are
extremely sensitive to surges as well as to discharges of static electricity.
When working on and with electronic parts and components, follow the generally
applicable ESD guidelines.
As a general rule, noax recommends first touching a metal part, such as the system
carrier plate or connector plate, followed by the electronic part or component.
Warning
Do not touch the golden contacts of the parts and components.
