Installation Guide

• Mount the unit on a flat surface inside your control cabinet.
• Connect the RJ-45 port to your EtherNet/IP network or PoE switch.
• Link N-bus amplifiers using the wiring-saving connector, up to 16 units.
• Keep total passing current at 1,200 mA or less across all amplifiers.
• Wire 24 VDC to the power connector, or draw power through PoE instead.
• Set the requested packet interval between 0.5 and 10,000 ms in your PLC.
• Verify that ambient temperature stays within -20 to +55 °C.
• Use shielded Ethernet cable no longer than 100 m for stable links.

Key Performance Highlights

• The NU-EP1 supports 64 simultaneous EtherNet/IP connections for flexible network design.
• PoE Class 3 operation removes the need for a separate power run in many installations.
• Cyclic and message communication cover fast control data and configuration reads.
• The unit handles up to 16 N-bus amplifiers with a single wiring-saving connector.
• Low power draw of 1,500 mW or less keeps cabinet heat minimal.
• A wide operating range of -20 to +55 °C suits harsh factory floors.
• Humidity tolerance of 35 to 85% RH supports most industrial environments.
