Page 2: Important User Information
2 FLEX I/O Power Supply Modules 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.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices. -
Page 3: Environment And Enclosure
FLEX I/O Power Supply Modules 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 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is not intended for use in residential environments and may not provide adequate protection to radio communication services in such environments. - Page 4 4 FLEX I/O Power Supply Modules ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding.

FLEX I/O Power Supply Modules Install Your Power Supply Module 1794-PS13 shown ATTENTION: During mounting of all devices, be sure that all debris (metal chips, wire strands, etc.) is kept from falling into the module. Debris that falls into the module could cause damage on power up. Hook the lip on the rear of the power supply module onto the top of the DIN rail, and rotate the power supply module onto the rail. -
Page 8: Connect Wiring For Your Power Supply Module
Power POWER SUPPLY 1794-PS3 1794-PS3 shown Terminals A, B and C are 120/230V AC supply terminals. Terminals D, E and F are available to daisychain this 120/230V AC power to other 1794-PS power supply modules. If applying 120/230V AC power to the power supply, you can also power the corresponding 120/230V AC modules in your FLEX I/O system. - Page 9 FLEX I/O Power Supply Modules Repeat steps 3 and 4 using terminals I and J for the second adapter. ATTENTION: The total length of wire for terminals H, I, J and G must not exceed 3m (9.8ft). Exceeding the 3m (9.8ft) length can reduce noise immunity. Connections D, E and F are used to pass 120/230V AC power to adjacent 1794 power supplies, or to power any corresponding120/230V AC modules in your FLEX I/O system.
