Before You Begin
Know the basics and safety requirements for each component in your system before you perform any maintenance, test, or repair procedures. Visit ni.com/docs to review the safety documents that apply to your system.
There are a variety of solution integration options available for your application-specific system requirements. Depending on the configuration of your system and the level of customization by an integrator, some of the procedures and concepts described in this document may not be applicable to your solution. Consult your system integrator for any instructions not provided in this document.
The term integrator refers to the company or person responsible for customizing the system and software as delivered from NI.
