Universal I/O Chassis ATTENTION ! 3 Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664–1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance. This equipment is supplied as “open type” equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present, and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications. See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosures. Also, see the appropriate sections in this publication, as well as the Allen–Bradley publication 1770–4.1, (“Industrial Automation Wiring and Grounding Guidelines”), for additional installation requirements pertaining to this equipment. 4 Universal I/O Chassis Prepare for Installation I/OĆgroupĆlabel set (cat. no. 1771ĆXB) Make sure you have these items: Hardware kit (cat. no. 1771ĆRK) Documentation (if you are installing I/O modules or power supplies) plastic keying bands (number depends on size of chassis) • 9 1771ĆA1B • 18 1771ĆA2B • 27 1771ĆA3B, 1771ĆA3B1 • 36 1771ĆA4B 1 star washer 1 cup washer I/O Module Cat.

To prevent ground loops from occurring, use only one grounding stud when grounding your equipment. Use the following information, along with the installation manual for your programmable controller to ground the I/O chassis and your I/O modules. Chassis Ground SingleĆpoint Grounding When you connect grounding conductors to the I/O chassis grounding stud, place a star washer under the first lug, then place a nut with captive lock washer on top of each ground lug.

Place the first lug between a star washer and a nut with a captive star washer. After tightening the nut, place the second lug between the first nut and a second nut with a captive star washer. Connect an equipment grounding conductor directly from each chassis to an individual bolt on the ground bus. a ground stud the grounding stud Publication 1771ĆIN075A-EN-P - March 2002 12 Universal I/O Chassis The grounding-electrode system is at earth-ground potential and is the central ground for all electrical equipment and ac power within any facility. Use a grounding-electrode conductor to connect the ground bus to the grounding-electrode system. Use at minimum 8 AWG copper wire for the grounding-electrode conductor to guard against EMI. The National Electrical Code specifies safety requirements for the grounding-electrode conductor. Certain connections require shielded cables to help reduce the effects of electrical noise coupling. Ground each shield at one end only. A shield grounded at both ends forms a ground loop which could cause faulty PLC-5 processor operation. Ground each shield at the end specified in the appropriate publication for the product. Avoid breaking shields at junction boxes. Many types of connectors for shielded conductors are available from various manufacturers. If you do break a shield at a junction box: • connect only category-2 conductors in the junction box • do not strip the shield back any further than necessary to make a connection • connect the shields of the two cable segments to ensure continuity along the entire length of the cable For more information about grounding the chassis, see Industrial Automation Wiring and Grounding Guidelines (publication 1770-4.1).

The 1772-LSP, -LWP, -LXP, and -LZP processor IMPORTANT modules already contain a power supply so you can only parallel one additional power-supply module with these processor modules. ATTENTION ! WARNING ! WARNING ! # Do not connect an external power supply and a power-supply module to the same I/O chassis; they are incompatible. If you insert or remove any module or power supply while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure power is removed or the area is nonhazardous before proceeding. If you connect or disconnect any cable or wiring with power applied to this module or the device on the other end of the cable or wire, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure power is removed or the area is nonhazardous before proceeding. !
