POINT I/O 120/240V ac Expansion Power Supply Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.literature.rockwellautomation.
POINT I/O 120/240V ac Expansion Power Supply 3 ATTENTION 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.
POINT I/O 120/240V ac Expansion Power Supply ATTENTION Preventing Electrostatic Discharge 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.

POINT I/O 120/240V ac Expansion Power Supply You can use multiple ac expansion power supplies with POINT I/O adapters to assemble a full system. For instance, if you are using the 1734-ADN adapter, you may use an ac expansion power supply to add additional modules in 4 to 17 module increments. For example, if you had a 36 module system with a 1734 POINT I/O adapter, you would have two 1734-EPAC ac expansion power supplies to provide more PointBus current for modules to the right of the supply.
POINT I/O 120/240V ac Expansion Power Supply 7 WARNING When you connect or disconnect the removable 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. 2. Remove the module to the right of the power supply from its base unit. 3. Use a small-bladed screwdriver to rotate the DIN-rail locking screw to a vertical position.
