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 typically about 2.5% to 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 external options (input reactor, radio noise reduction filters, etc.) is not included in the
calorific values in the table.
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
