POINT I/O Field Potential Distributor Modules 3 Environment and Enclosure ATTENTION: 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 (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
POINT I/O Field Potential Distributor Modules North American Hazardous Location Approval The following information applies when operating this equipment in hazardous locations: Informations sur l’utilisation de cet équipement en environnements dangereux: Products marked "CL I, DIV 2, GP A, B, C, D" are suitable for use in Class I Division 2 Groups A, B, C, D, Hazardous Locations and nonhazardous locations only.
POINT I/O Field Potential Distributor Modules 5 European Hazardous Location Approval The following applies when the product bears the Ex Marking This equipment is intended for use in potentially explosive atmospheres as defined by European Union Directive 94/9/EC.
POINT I/O Field Potential Distributor Modules About the Module The purpose of the POINT I/O™ Field Potential Distributor module is to break the field power distribution. Use the module to change the field power distribution source for I/O modules to the right of the module. This facilitates logical or functional partitioning of low-channel count, high I/O-mix applications using the 1734-adapters, 1734-PDN, and 1734D Series communication interfaces.
POINT I/O Field Potential Distributor Modules 7 Install the Module To install the module on the DIN rail, proceed as follows: 1. Position the module vertically above the DIN rail. 2. Engage the interlocking pieces with the unit on the left. 3. Press down firmly to install the module on the DIN rail. The locking mechanism locks the module to the DIN rail. ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding.
POINT I/O Field Potential Distributor Modules Remove the Module To remove a 1734-FPD module, you must first remove any I/O module installed in the base to the right. To remove the 1734-FPD module from the DIN rail, proceed as follows: 1. Pull up on the RTB removal handle to remove the terminal block. 45727 2. Use a small-bladed screwdriver to rotate the DIN rail locking screw to a vertical position. This releases the locking mechanism. 3. Lift straight up to remove.

This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. ATTENTION: Do not wire more than 2 conductors on any single terminal.
