Safety Guidelines

Operate the NI USB-9229/9239 only as described in these operating instructions.

Hot Surface This icon denotes that the component may be hot. Touching this component

may result in bodily injury.

Safety Guidelines for Hazardous Voltages

If hazardous voltages are connected to the module, take the following precautions. A hazardous voltage is a voltage greater than 42.4 V 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 Make sure that devices and circuits connected to the module are properly

insulated from human contact.

Caution When module terminals are hazardous voltage LIVE (>42.4V

must ensure that devices and circuits connected to the module are properly insulated from human contact. You must use the NI 9971 connector backshell kit to ensure that the terminals are not accessible.

Figure 3 shows the NI 9971 connector backshell.

Refer to the Installing the NI USB-9229/9239 Device for more information about installing the backshell.
