Amount of heat generated by the inverter
Installing the heat sink inside the enclosure
When the heat sink is installed inside the enclosure, the amount of heat generated by the inverter unit and converter unit is
shown in the following tables.

NOTE
• The amount of heat generated shown assumes that the output current is the inverter rated current, and the carrier frequency
is 2 kHz.
Installing the heat sink outside the enclosure
When the heat sink is protruded through a panel, the amount of heat generated by the inverter unit and converter unit is
shown in the following tables. (For the details on protruding the heat sink through a panel, refer to
