3. Product Features

• Based on Niagara® Framework: Adopts Schneider Electric’s leading Niagara® software platform, supporting cross-protocol (BACnet, LonWorks, Modbus, etc.) integration, and providing graphical programming and data visualization interfaces.
• High-Reliability Design: Built-in battery (e.g., UNC-400-BAT) and battery/ground harness (UNC-400-HRN) ensure critical data and system time are preserved in case of power failure.
• Modular Interfaces: Equipped with multiple standard interfaces (RS-232, RS-485, LonWorks, BACnet), which can be flexibly configured by replacing connectors (e.g., E24-1555-2, E24-1604-3).
• Web Access: With the optional UNC-520-WEB Option, users can remotely monitor and control the system directly through a web browser without a dedicated client.

4. Structure and Composition

• Controller Body: The core computing unit that runs the Niagara® software.
• Communication Interfaces: Including RJ-45 ports (Ethernet, RS-232/RS-485), LonWorks interface, and BACnet interface.
• Power Supply and Battery Modules: Such as UNC-400-BAT (12Vdc, 1.2AH) and UNC-400-HRN (battery/ground harness).
• Optional Modules:
  • UNC-520-WEB Option: Adds web browser support to the controller.
  • Adapters and Cables: Such as UNCC-405 (RJ-45 to DB-9 Null Modem Adapter), CBL-RJ45-4/10/25 (silver satin patch cables of different lengths).

6. Installation and Maintenance

Installation

• Mount the controller on a DIN rail or in a cabinet.
• Connect the network (Ethernet) and other communication buses (RS-485, LonWorks) as required.
• Ensure correct power wiring; it is recommended to connect a backup battery to prevent data loss.

Maintenance

• Regularly check the battery power (e.g., UNC-400-BAT) and replace it when necessary.
• Inspect interface connections to ensure patch cables (e.g., CBL-RJ45-4) are in good condition.
• Perform firmware upgrades and configuration backups through a web browser (if the UNC-520-WEB Option is installed) or a dedicated client.
