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 9265. 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 9265 only as described in this document.
Caution Do not operate the NI 9265 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 the following limits.

Isolation Voltages

Channel-to-earth ground, Vsup-to-earth ground, or
COM-to-earth ground
Continuous
up to 2,000 m altitude 250 Vrms,| Measurement Category II
up to 5,000 m altitude 60 VDC,| Measurement Category I

Withstand
up to 2,000 m altitude 2,300 Vrms, verified by a 5 s dielectric withstand test
up to 5,000 m altitude 1,000 Vrms, verified by a 5 s dielectric withstand test

Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage  sources, and electronics.
Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system.
This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.
Note Do not connect the NI 9265 to signals or use for measurements within Measurement Categories III or IV.

Safety Guidelines for Hazardous Voltages
If hazardous voltages are connected to the device, take the following precautions. A hazardous voltage is a voltage greater than 42.4 Vpk voltage or 60 VDC to earth ground.
Caution Ensure that hazardous voltage wiring is performed only by qualified personnel adhering to local electrical standards.
Caution Do not mix hazardous voltage circuits and human-accessible circuits on the same module.
Caution Ensure that devices and circuits connected to the module are properly insulated from human contact.
Caution When module terminals are hazardous voltage LIVE (>42.4 Vpk/60 VDC), you must ensure that devices and circuits connected to the module are properly insulated from human contact. You must use the NI 9927 connector backheel kit to ensure that the terminals are not accessible.

Safety Guidelines for Hazardous Locations
The NI 9265 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 9265 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.
Caution For Division 2 and Zone 2 applications, install the system in an enclosure rated to at least IP54 as defined by IEC/EN 60079-15.
Caution For Division 2 and Zone 2 applications, connected signals must be within the following limits.

Special Conditions for Hazardous Locations Use in Europe and Internationally The NI 9265 has been evaluated as Ex nA IIC T4 Gc equipment under DEMKO Certificate No. 03 ATEX 0324020X and is IECEx 14.0089X certified. Each NI 9265 is marked II 3G and is suitable for use in Zone 2 hazardous locations, in ambient temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI 9265 in Gas Group IIC hazardous locations, you must use the device in an NI chassis that  has been evaluated as Ex nC IIC T4, Ex IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.

Caution You must make sure that transient disturbances do not exceed 140% of the rated voltage.
Caution The system shall only be used in an area of not more than Pollution Degree 2, as defined in IEC 60664-1.
Caution The system shall be mounted in an ATEX/IECEx-certified enclosure with a minimum ngress protection rating of at least IP54 as defined in IEC/EN 60079-15.
Caution The enclosure must have a door or cover accessible only by the use of a tool.

Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for electromagnetic compatibility (EMC) stated in the product specifications. These requirements and limits provide reasonable protection against harmful interference when the product is operated in the intended operational electromagnetic environment.
This product is intended for use in industrial locations. However, harmful interference may occur in some installations, when the product is connected to a peripheral device or test object, or if the product is used in residential or  commercial areas. To minimize interference with radio and television reception and prevent unacceptable performance degradation, install and use this product in strict accordance with the instructions in the product documentation.

Furthermore, any changes or modifications to the product not expressly approved by National Instruments could void your authority to operate it under your local regulatory rules.
Special Conditions for Marine Applications
Some products are Lloyd’s Register (LR) Type Approved for marine (shipboard) applications. To verify Lloyd’s Register certification for a product, visit ni.com/certification and search for the LR certificate, or look for the Lloyd’s Register  mark on the product.
Caution In order to meet the EMC requirements for marine applications, install the product in a shielded enclosure with shielded and/or filtered power and input/output ports. In addition, take precautions when designing, selecting,  and installing measurement probes and cables to ensure that the desired EMC performance is attained.

Preparing the Environment

Ensure that the environment in which you are using the NI 9265 meets the following specifications.

Indoor use only.
Note Refer to the device datasheet on ni.com/manuals for complete specifications.

Connecting the NI 9265

Figure 1. NI 9265 Pinout

Note You must use 2-wire ferrules to create a secure connection when connecting more than one wire to a single terminal on the NI 9265.

NI 9265 Signals
The NI 9265 has four analog output channels, AO. Each channel has a common terminal, COM, that is internally connected to the isolated ground reference of the module. The NI 9265 also has a terminal for an external power supply, Vsup, and an external power supply common terminal, Power Supply COM.
Connecting a Load
You can connect a load to each channel of the NI 9265.

Figure 2. Connecting a Load to the NI 9265

Connecting an External Power Supply

You must connect an external power supply to the NI 9265. This power supply provides the current for the devices you connect to the module.
When the module powers on, the channels output the startup current.
High-Vibration Application Connections
If your application is subject to high vibration, NI recommends that you follow these guidelines to protect connections to the NI 9265:

• Use ferrules to terminate wires to the detachable connector.
• Use the NI 9927 backshell kit with the NI 9265 with screw terminal or the NI 9981 backshell kit with the NI 9265 with spring terminal.
