Secure DIN rail to mounting surface approximately every 200 mm (7.87 in.) and use end-anchors appropriately. Publication 1734-IN010C-EN-E - January 2007 4 POINT I/O 120V ac Input Module Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial ATTENTION environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters (6562 feet) 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 enclosure must have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. 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. Besides this publication, see: • Industrial Automation Wiring and Grounding Guidelines, for additional installation requirements, Allen-Bradley publication 1770-4.1. • NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure.

This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation. 1. Using a bladed screwdriver, rotate the keyswitch 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, noting that you cannot insert the module if the locking mechanism is unlocked. 3. Insert the module straight down into the mounting base and press to secure so that the module locks into place. Install the Removable Terminal Block (RTB) A removable terminal block (RTB) is supplied with your wiring base assembly. To remove, pull up on the RTB handle. You can remove and replace without removing any of the wiring. To reinsert the RTB, proceed as follows. 1. Insert the end opposite the handle into the base unit, noting that 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. Publication 1734-IN010C-EN-E - January 2007 12 POINT I/O 120V ac Input Module 3.
