EtherNet/IP and Flex I/O System Integration
The 1794-PS3 operates as a power distribution component within the Allen-Bradley Flex I/O platform. The module supplies regulated DC power for Flex I/O adapters and I/O modules, supporting system expansion through the Flex I/O backplane architecture. Power loading must be calculated according to connected adapter and I/O module requirements to maintain the specified supply output limits.

Field Installation Guidelines
- Install the power supply module according to the Flex I/O system mounting requirements and maintain correct mechanical engagement with adjacent modules.
- Verify AC input wiring polarity, protective grounding, and terminal connections before energizing the system.
- Separate AC power conductors from low-level I/O signal wiring to reduce electrical interference.
- Use appropriate shield termination practices for connected signal cables where required by the installation environment.
- Confirm total Flex I/O module and adapter current demand does not exceed the available DC output current rating.
- Check enclosure ventilation and thermal conditions to prevent excessive heat accumulation around the power supply module.
- Follow Allen-Bradley Flex I/O installation documentation for grounding, wiring, and maintenance procedures.
