GETTING STARTED GUIDE

NI 9775
4-Ch, ±10 V, 20 MS/s, 14-Bit Digitizer

This document explains how to connect to the NI 9775.

• Note Before you begin, complete the software and hardware installation procedures in your chassis documentation.
• Note The guidelines in this document are specific to the NI 9775. The other components in the system might not meet the same safety ratings. Refer to the documentation for each component in the system to determine the safety and EMC ratings for the entire system.

Safety Guidelines

Operate the NI 9775 only as described in this document.

• Caution Do not operate the NI 9775 in a manner not specified in this document. Product misuse can result in a hazard. You can compromise the safety protection built into the product if the product is damaged in any way. If the product is damaged, return it to NI for repair.

Safety Voltages

Connect only voltages that are within Measurement Category O.

Isolation

• Channel-to-channel None
• Channel-to-earth ground None

Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.

Caution Do not connect the NI 9775 to signals or use for measurements within Measurement Categories II, III, or IV.

Safety Guidelines for Hazardous Locations
The NI 9775 is suitable for use in Class I, Division 2, Groups A, B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4 and Ex nA IIC T4 hazardous locations; and nonhazardous locations only. Follow these guidelines if you are installing the NI 9775 in a potentially explosive environment. Not following these guidelines may result in serious injury or death.

• Caution Do not disconnect I/O-side wires or connectors unless power has been switched off or the area is known to be nonhazardous.
• Caution Do not remove modules unless power has been switched off or the area is known to be nonhazardous.
• Caution Substitution of components may impair suitability for Class I, Division 2.
