■ Current reduction curve
The current value of the inverter that can be output continuously varies depending on the installation
method, ambient temperature, and the setting of carrier frequency.
For details, refer to "Instruction manual for load reduction" (E6582116).
■ Calorific values of inverter and required ventilation
The inverter will lose the power slightly as a result of conversion from AC to DC or from DC to AC. In
order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the
interior of the cabinet must be ventilated and cooled.
