Toshiba Tosvert VF-S15 Instruction Manual page 44

The space shown in the diagram is the minimum allowable space. Because air cooled equipment has cooling
fans built in on the top or bottom surfaces, make the space on top and bottom as large as possible to allow
for air passage.

 Calorific values of the inverter and the required ventilation
About 5% of the rated power of the inverter will be lost 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.
The amount of forcible air-cooling ventilation required and the necessary heat discharge surface quantity
when operating in a sealed cabinet according to motor capacity are as follows.

Note 2) It is power consumption when power is on but is not output (0Hz), and cooling fan is activated (model
Do not install in any location where there is high humidity or high temperatures and where there are
large amounts of dust, metallic fragments and oil mist.
