Installation Guide

• Mount the unit on a DIN rail or panel inside the control cabinet.
• Wire 24 VDC power and keep ripple within 10% peak-to-peak.
• Use Cat 5 or better shielded cable, and keep each run under 100 m.
• Connect N-bus amplifiers through the wiring-saving connector.
• Keep total passing current at or below 1,200 mA across all amplifiers.
• Load the GSDML V2.3 file into your engineering tool before setup.
• Assign the device name and IP address through DCP.
• Set the update time between 2 and 512 ms to match cycle needs.
• Confirm LLDP topology so the controller sees the correct port links.

Environmental and Interference Performance

• The NU-PN1 runs from -20 to +55 °C for cold and warm plant areas.
• Humidity tolerance of 35 to 85% RH covers most indoor cabinets.
• PROFINET with LLDP and DCP gives reliable device identification and diagnostics.
• Shielded twisted-pair cable limits noise pickup on the factory floor.
• Conformance class A support fits standard cyclic I/O applications.
