Vy\u017eaduje si vlastn\u00fa ochranu proti nadpr\u00fadu (jednoduch\u00fa poistku alebo miniat\u00farny isti\u010d) a mus\u00ed by\u0165 nap\u00e1jan\u00fd v\u017edy, ke\u010f hlavn\u00fd motor be\u017e\u00ed akouko\u013evek r\u00fdchlos\u0165ou \u2013 vr\u00e1tane peri\u00f3d n\u00e1behu a rozbehu meni\u010da frekvencie (VFD). Najjednoduch\u0161ie zapojenie je pripoji\u0165 nap\u00e1janie motora ventil\u00e1tora k rovnak\u00e9mu zdroju nap\u00e1jania ako vstupn\u00e9 nap\u00e1janie VFD prostredn\u00edctvom vlastnej poistky, tak\u017ee ventil\u00e1tor be\u017e\u00ed v\u017edy, ke\u010f je VFD nap\u00e1jan\u00fd.
