Calorific values of the inverter and the required ventilation<br />
A-22<br />
E6581381<br />
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<br />
AC. In order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the<br />
interior of the cabinet must be ventilated and cooled.<br />
The amount of forcible air-cooling ventilation required and the necessary heat discharge surface quantity<br />
when operating in a sealed cabinet according to motor capacity are as follows.<br />
Note1: The heat loss for the optional external devices (input reactor, radio noise reduction filters, etc.) is not<br />
included in the calorific values in the table<br />

Panel designing taking into consideration the effects of noise<br />
The inverter generates high frequency noise. When designing the control panel setup, consideration must be<br />
given to that noise. Examples of measures are given below.<br />
• Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the<br />
same conduit, do not run them parallel, and do not bundle them.<br />
• Provide shielding and twisted wire for control circuit wiring.
