ABB NTAI02 is a Analog Input Termination Unit documented for the applicable Bailey Infi 90 system configuration. Its recorded specification includes unit function Analog input termination, system family INFI 90 / Harmony, installation Panel-mounted field termination. Correct selection depends on the complete article identity, installed equipment, mechanical or electrical interfaces and the documented configuration rather than appearance alone. Using the exact model helps maintenance teams avoid incompatible revisions, connector arrangements and application variants.
Before installing NTAI02, record the original nameplate, installed position, connected assemblies and every relevant configuration detail. Compare the supplied unit with the existing hardware and applicable ABB service documentation, isolate all affected energy sources and preserve required settings or calibration data. After installation, inspect each affected interface and complete controlled functional checks before returning the equipment to service.
