Safety Guidelines

Caution Operate the hardware only as described in these operating instructions.
The following section contains important safety information that you must follow when installing and using the USB-6008/6009.
Do not operate the USB-6008/6009 in a manner not specified in this document. Misuse of the device can result in a hazard. You can compromise the safety protection built into the device if the device is damaged in any way. If the device is damaged, contact National Instruments for repair.
Do not substitute parts or modify the device except as described in this document. Use the device only with the chassis, modules, accessories, and cables specified in the installation instructions. You must have all covers and filler panels installed during operation of the device.
USB-6008/6009 User Guide and Specifications 2 ni.com
Do not operate the device in an explosive atmosphere or where there may be flammable gases or fumes. If you must operate the device in such an environment, it must be in a suitably rated enclosure.
If you need to clean the device, use a dry cloth. Make sure that the device is completely dry and free from contaminants before returning it to service.
Operate the device only at or below Pollution Degree 2. Pollution is foreign matter in a solid, liquid, or gaseous state that can reduce dielectric strength or surface resistivity. The following is a description of pollution degrees:
Pollution Degree 1 means no pollution or only dry, nonconductive pollution occurs. The pollution has no influence.
Pollution Degree 2 means that only nonconductive pollution occurs in most cases. Occasionally, however, a temporary conductivity caused by condensation must be expected.
Pollution Degree 3 means that conductive pollution occurs, or dry, nonconductive pollution occurs that becomes conductive due to condensation.
You must insulate signal connections for the maximum voltage for which the device is rated. Do not exceed the maximum ratings for the device. Do not install wiring while the device is live with electrical signals. Do not remove or add connector blocks when power is connected to the system. Avoid contact between your body and the connector block signal when hot swapping modules. Remove power from signal lines before connecting them to or disconnecting them from the device.
Operate the device at or below the Measurement Category I circuits are subjected to working voltages

Software

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). Examples of Measurement Category II are measurements performed on household appliances, portable tools, and similar E Series devices.
Measurement Category III is for measurements performed in the building installation at the distribution level. This category refers to measurements on hard-wired equipment such as equipment in fixed installations, distribution boards, and circuit breakers. Other examples are wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and stationary motors with permanent connections to fixed installations.
Measurement Category IV is for measurements performed at the primary electrical supply installation (<1,000 V). Examples include electricity meters and measurements on primary overcurrent protection devices and on ripple control units.
Software support for the USB-6008/6009 for Windows 2000/XP is provided by NI-DAQmx.
Note For information about non-Windows operating system support, refer to

Setting Up Hardware

Complete the following steps to set up the hardware:
1. Install combicon screw terminal blocks by inserting them into the combicon jacks.
Note The USB-6008/6009 kit ships with signal labels. You can apply the signal labels to
the screw terminal blocks for easy signal identification.
2. Refer to Table 3 and Figure 4 for label orientation and affix the provided signal labels to the screw terminal blocks. Until the signal labels are applied, you can insert the screw terminal blocks into either of the combicon jacks. Refer to Figure 4 for more information about signal label orientation.
