Working Principle The module connects at the physical end of UCN twisted pair trunk. The built-in precision resistor matches the characteristic impedance of UCN communication cable. It absorbs reflected signal at cable end and prevents waveform distortion and data packet loss. Signal monitoring circuit samples communication signal continuously, judges cable fault or excessive attenuation and sends fault alarm to UCN network system.
Installation Requirements Only install at two physical endpoints of UCN backbone; Fasten twisted pair terminal connection reliably; Connect protective ground wire to cabinet ground bar; Keep UCN communication cable away from high power motor and inverter cables; Verify network communication stability after installation.
Precautions for Use Do not install termination module at non-terminal position of UCN trunk; Do not access high voltage signal to communication port; Inspect cable terminals regularly; Replace module when UCN communication attenuation alarm occurs.
