\nAqu\u00ed tambi\u00e9n se hace hincapi\u00e9 en una parte del aparato. La explicaci\u00f3n de la Nota 1 es m\u00e1s rigurosa, porque la definici\u00f3n aqu\u00ed estipula tensi\u00f3n muy baja de seguridad, pero la tensi\u00f3n muy baja de seguridad es solo una parte que se puede tocar si cumple con los requisitos de 8.1.4.

\nEl aparato se alimenta mediante un adaptador enchufable (sin conexi\u00f3n a tierra protectora), y el adaptador y el aparato se entregan al usuario juntos. El adaptador y el aparato se consideran en conjunto aparatos de Clase II. Debido a que el adaptador es Clase II, esto determina la clase de protecci\u00f3n contra descargas el\u00e9ctricas. Sin embargo, el aparato – ventilador por s\u00ed solo es una construcci\u00f3n de Clase III, es decir, una construcci\u00f3n de Clase III en un aparato de Clase II.
\n
\nPor supuesto, existe otra situaci\u00f3n, es decir, una PCB de fuente de alimentaci\u00f3n conmutada est\u00e1 integrada en el aparato, y esta PCB de fuente de alimentaci\u00f3n conmutada puede proporcionar un circuito SELV. Entonces, la parte del circuito SELV constituye una construcci\u00f3n de clase II.
