\nL\u00e0 encore, l’accent est mis sur une partie de l’appareil. L’explication de la Note 1 est plus rigoureuse, car la d\u00e9finition stipule ici la tr\u00e8s basse tension de s\u00e9curit\u00e9, mais la tr\u00e8s basse tension de s\u00e9curit\u00e9 n’est qu’une partie qui peut \u00eatre touch\u00e9e si elle satisfait aux exigences de 8.1.4.

\nL’appareil est aliment\u00e9 par un adaptateur enfichable (sans mise \u00e0 la terre de protection), et l’adaptateur et l’appareil sont livr\u00e9s ensemble \u00e0 l’utilisateur. L’adaptateur et l’appareil sont ensemble consid\u00e9r\u00e9s comme des appareils de classe II. L’adaptateur \u00e9tant de classe II, cela d\u00e9termine la classe de protection contre les chocs \u00e9lectriques. Cependant, l’appareil – ventilateur seul est une construction de classe III, c’est-\u00e0-dire une construction de classe III dans un appareil de classe II.
\n
\nBien s\u00fbr, il existe une autre situation, c’est-\u00e0-dire qu’un PCB d’alimentation \u00e0 commutateur est int\u00e9gr\u00e9 dans l’appareil, et ce PCB d’alimentation \u00e0 commutateur peut fournir un circuit SELV. Ensuite, la partie circuit SELV constitue une construction de classe II.
