(*1): Rated output capacity indicates a value based on the condition that output voltage is 220 V in case of the 200 V class or
440 V in case of the 400 V class.
(*2): The models of 30 kW or higher have neither cover for the wiring hole that has a big aperture nor space for bending
external cables inside the unit. When a protector is installed externally, use an optional cover for the wiring hole.
(*3): Allowable voltage variation is +/-10 % in continuously operation (100 % load)
(*4): Be sure to attach DC reactor (option) for the models: 200V class 75kW or more and 400V class 110kW or more.
(Not necessary for DC input.)
(*5): This regulation is overload value from the stop state at ambient temperature state within regulation value.
