*1. Conversion: The set current value will be converted at the ratio of the rated current for the heavy load/light load mode.
(Example) If you change from a light load mode setting of 5 A (rated current: 10 A) to the heavy load mode (rated current:
8 A), the current value will be converted as follows: Rated current 8 A × 50% (5 A/10 A) = 4 A.
*2. Setting in steps: Steps of 0.1/0.2/0.4/0.55/0.75/1.1/1.5/2.2/3.0/3.7/4.0/5.5/7.5/11.0/15.0/18.5 [kW] can be selected.
