NOTE 2 A chaque fois qu’il est fait référence à 230 V ou 400 V dans cette norme, les valeurs à prendre en
compte peuvent être respectivement 220 V ou 240 V et 380 V ou 415 V.

compte peuvent être 100 V ou 120/208 V.

NOTE Au Japon, le conducteur phase-neutre et le conducteur phase-terre (conducteur à la masse) sont pensés
différemment, car les systèmes monophasés à 2 fils alimentés par une source de système à 2 fils ne possèdent
pas de point neutre.
