Publication 1734-IN587B-EN-P - March 2002 4 POINT I/O 2 Relay Output Module 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 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 enclosure. 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. POINT I/O is grounded through the DIN rail to ATTENTION chassis ground. Use zinc plated, yellow chromated steel DIN rail to assure proper grounding. Using other DIN rail materials (e.g. aluminum, plastic, etc.) which can corrode, oxidize or are poor ! conductors can result in improper or intermittent platform grounding. Publication 1734-IN587B-EN-P - March 2002 POINT I/O 2 Relay Output Module 5 EXPLOSION HAZARD WARNING • Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous. • Do not disconnect connections to this equipment ! unless power has been removed or the area is known to be nonhazardous. Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this product. • Substitution of components may impair suitability for Class I, Division 2. • If this product contains batteries, they must only be changed in an area known to be nonhazardous. Preventing Electrostatic Discharge ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines ! when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards. • Do not touch circuit components inside the equipment. • If available, use a static-safe workstation. • When not in use, store the equipment in appropriate static-safe packaging. Publication 1734-IN587B-EN-P - March 2002 6 POINT I/O 2 Relay Output Module Installing the Mounting Base To install the mounting base on the DIN rail, proceed as follows. 1. Position the mounting base vertically above the installed units (adapter, power supply or existing module. 2. Slide the mounting base down allowing the interlocking side pieces to engage the adjacent module or adapter. 3. Press firmly to seat the mounting base on the DIN rail. The mounting base will snap into place. 4. To remove the mounting base from the DIN rail, remove the module, and use a small bladed screwdriver to rotate the base locking screw to a vertical position. This releases the locking mechanism. Then lift straight up to remove. Installing the I/O Module The module can be installed before, or after base installation. Make sure that the mounting base is correctly keyed before installing the module into the mounting base. In addition, make sure the mounting base locking screw is positioned horizontal referenced to the base. When you insert or remove the module while WARNING backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous ! before proceeding. 1. Using a bladed screwdriver, rotate the keyswitch (2) on the mounting base clockwise until the number required for the type of module being installed aligns with the notch in the base. 2. Make certain the DIN rail locking screw is in the horizontal position. (You cannot insert the module if the locking mechanism is unlocked.) Publication 1734-IN587B-EN-P - March 2002 POINT I/O 2 Relay Output Module 7 3. Insert the module straight down into the mounting base and press to secure. The module will lock into place. Installing the Removable Terminal Block (RTB) A removable terminal block is supplied with your wiring base assembly. To remove, pull up on the RTB handle. This allows the mounting base to be removed and replaced as necessary without removing any of the wiring. To reinsert the removable terminal block, proceed as follows. When you connect or disconnect the Removable WARNING Terminal Block (RTB) with field side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. ! Be sure that power is removed or the area is nonhazardous before proceeding. 1. Insert the end opposite the handle into the base unit. This end has a curved section that engages with the wiring base. 2. Rotate the terminal block into the wiring base until it locks itself in place. 3. If an I/O module is installed, snap the RTB handle into place on the module. Publication 1734-IN587B-EN-P - March 2002 8 POINT I/O 2 Relay Output Module Removing a Mounting Base To remove a mounting base, you must remove any installed module, and the module installed in the base to the right. Remove the removable terminal block (if wired). 1. Unlatch the RTB handle on the I/O module. 2. Pull on the RTB handle to remove the removable terminal block. When you connect or disconnect the Removable WARNING Terminal Block (RTB) with field side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. ! Be sure that power is removed or the area is nonhazardous before proceeding. 3. Press on the module lock on the top of the module. 4. Pull on the I/O module to remove from the base. When you insert or remove the module while WARNING backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous ! before proceeding. 5. Repeat steps 1, 2, 3 and 4 for the module to the right. 6. Use a small bladed screwdriver to rotate the orange base locking screw to a vertical position. This releases the locking mechanism. 7. Then lift straight up to remove.
