Calorific values of the inverter and the required ventilation
The energy loss when the inverter converts power from AC to DC and then back to AC is about 5%. 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.
The amount of forced air-cooling ventilation required and the necessary heat exchange surface area when operating
in a sealed cabinet according to motor capacity are as follows.

Note1: The heat loss for the optional external devices (input reactor, DC reactor, radio noise reduction filters, etc.) is
not included in the calorific values in the table. With the exception of inverters indented for motors with
capacities of 400kW and above, in which case the calorific value of the DC reactor is included.
Note2: Each calorific value in the table refers to the quantity of heat that an inverter produces when it is operated
continuously at the factory default
 (carrier frequency) under a load factor of 100%.
Note3: This value is power dissipated inside the enclosure with using heatsink outer option.
