(*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 22 kW or lower has no control power supply terminals(R0, S0). Optional control power supply is available
for those types.
(*3): There are three openings for wiring; namely, wiring holes for main circuit input, for main circuit output and for control
circuit. After wiring is complete, close the openings properly.
(*4): 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.
(*5): Allowable voltage variation is +/-10 % in continuously operation (100 % load).
(*6): This regulation is overload value from the stop state at ambient temperature state within regulation value.
