Safety Information

Caution The following paragraphs contain important safety information you must follow

when installing and operating the device.

Do not operate the device in a manner not specified in the documentation. Misuse of the device may result in a hazard and may compromise the safety protection built into the device. If the device is damaged, turn it off and do not use it until service-trained personnel can check its safety. If necessary, return the device to National Instruments for repair.

Keep away from live circuits. Do not remove equipment covers or shields unless you are trained to do so. If signal wires are connected to the device, hazardous voltages can exist even when the equipment is turned off. To avoid a shock hazard, do not perform procedures involving cover or shield removal unless you are qualified to do so. Disconnect all field power prior to removing covers or shields.

When using this accessory with the NI 8255R, three of the digital I/O signals on the device are not accessible. Refer to the Connectors section of the NI PCIe-8255R User Manual for more information.

If the device is rated for use with hazardous voltages (>30 V or 60 V

), it may require a safety earth-ground connection wire. Refer to

, 42.4 Vpk,

rms

the device specifications for maximum voltage ratings.

Because of the danger of introducing additional hazards, do not install unauthorized parts or modify the device. Use the device only with the chassis, modules, accessories, and cables specified in the installation instructions. All covers and filler panels must be installed while operating the device.

Do not operate the device in an explosive atmosphere or where flammable gases or fumes may be present. Operate the device only at or below the pollution degree stated in the specifications. Pollution consists of any foreign matter—solid, liquid, or gas—that may reduce dielectric strength or surface resistivity. The following is a description of pollution degrees.

• Pollution Degree 1—No pollution or only dry, nonconductive pollution occurs. The pollution has no effect.

• Pollution Degree 2—Normally only nonconductive pollution occurs. Occasionally, nonconductive pollution becomes conductive because of condensation.

• Pollution Degree 3—Conductive pollution or dry, nonconductive pollution occurs. Nonconductive pollution becomes conductive because of condensation.

Clean the device and accessories by brushing off light dust with a soft, nonmetallic brush. Remove other contaminants with a stiff, nonmetallic brush. The unit must be completely dry and free from contaminants before returning it to service.

Yo u must insulate signal connections for the maximum voltage for which the device is rated. Do not exceed the maximum ratings for the device. Remove power from signal lines before connection to or disconnection from the device.

Caution National Instruments measurement products may be classified as either

Measurement Category I or II. Operate products at or below the Measurement Category level specified in the hardware specifications.

• Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS

voltage. 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 (e.g., 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 products.

• 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.

Unpacking

The NI 8255R ships in an antistatic package to prevent electrostatic discharge from damaging device components. To avoid such damage in handling the device, take the following precautions:

• Ground yourself via a grounding strap or by holding a grounded object, such as the computer chassis.

• Touch the antistatic package to a metal part of the computer chassis before removing the device from the package.

Caution Never touch the exposed pins of connectors.

Measurement Category is also referred to as Installation Category.

MAINS is defined as the (hazardous live) electrical supply system to which equipment is designed to be connected for the purpose of powering the equipment. Suitably rated measuring circuits may be connected to the MAINS for measuring purposes.

Installation

Caution To protect yourself and the computer from electrical hazards, the computer must

remain unplugged until the installation is complete.

Remove the device from the package and inspect it for loose components or any other signs of damage. Notify National Instruments if the device appears damaged in any way. Do not install a damaged device in the computer.

Store the NI 8255R in the antistatic package when not in use.

The following instructions are for general installation. Refer to the documentation provided by your computer manufacturer for specific instructions and warnings about installing hardware in the computer. Refer to the Specifications section for a list of the typical power requirements for the NI 8255R.

1. Install NI Vision Acquisition Software before installing the NI 8255R device. Refer to the NI Vision Acquisition Software Release Notes for installation and configuration instructions.

2. Power off and unplug the computer.

3. Remove the computer cover to expose the expansion slots.

Caution Installing a PCIe device into a PCI, PCI-X, AGP, or any non-PCIe slot can

damage both the computer motherboard and the device. If you are unsure of the difference between connector types, do not install the device. Refer to the documentation provided by your computer manufacturer to determine the correct slot in which to install the NI 8255R.

4. Choose an unused x1 or larger PCIe slot, and remove the corresponding expansion slot cover on the back panel of the computer. Figure 1 shows the different types of expansion slots available on most computers.

Note The NI 8255R is intended for a x1 PCIe slot. The NI 8255R will fit into, and can be

used in a x4, x8, or x16 PCIe slot.
