Installation Guidelines
When installing the NT20S-ST121B-V1, ensure the panel cutout matches the specified dimensions to guarantee a proper environmental seal. Maintain adequate clearance around the rear enclosure of the terminal to facilitate passive ventilation and heat dissipation. All wiring connections, including the 24 VDC power supply, must be made using compliant cable types while strictly adhering to local electrical grounding codes to prevent electrical noise interference.
