Only use Class H or RK5 UL listed input fuses and UL listed breakers. See the table above for the
voltage and current ratings for the fuses and breakers.
Utiliser UNIQUEMENT des fusibles d’entrée homologués de Classe H ou RK5 UL et des disjoncteurs
UL. Se reporter au tableau ci-dessus pour la tension et le courant nominal des fusibless et des
disjoncteurs.
• If you install the recommended reactors, you can maintain the power factor above 85%, and
keep the THD below 40% for operations at the rated load. Improvements are reduced at lighter
loads.
• Cable impedance affects the input power factor and occurrence of harmonic waves. The input
power factor and THD improvement of the reactors may be lower depending on the
transformer capacity, the transformer impedance, and the cable length.
• Refer to the specifications table and install recommended reactors. Although a higher
inductance value (L) of the reactor results in an improvement in the power factor and better
suppression of harmonic effects, power loss increases at the same time due to voltage drop.
• The capacity of built-in DC reactors in some iS7 inverter models is based on the normal duty
load factor. Therefore, improvements may be reduced during a heavy duty operation.
