Safety Precautions
Sensor usage must comply with IEC 61800-5-1 standard. The sensor must be installed in electronic or electrical equipment that meets application standards and safety requirements as per the instructions. Caution: Risk of electric shock. During operation, certain parts of the sensor may carry dangerous voltages (e.g., primary busbars, power supply). Neglecting this can lead to damage and serious hazards. The sensor is an embedded device; ensure its conductive parts are not accessible after installation. Protective covers or shields may be installed if necessary. The main power supply must be disconnectable.
