Installing the heat sink outside the enclosure When the heat sink is installed outside the enclosure, the amount of heat generated by the inverter unit is shown in the following tables. (For details on protruding the heat sink through a panel, refer to page 45 .) The figures indicate the amount of heat generated when the output current is the rated current, power supply voltage is 220 V (200 V class) or 440 V (400 V class), and the carrier frequency is 2 kHz.
2.3.3 Cooling system types for inverter enclosure From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the permissible temperatures of the in-enclosure equipment including the inverter. The cooling systems are classified as follows in terms of the cooling calculation method. Cooling by natural heat dissipation from the enclosure surface (totally enclosed type) Cooling by heat sink (aluminum fin, etc.) 42 2.
