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.

Panel designing taking into consideration the effects of noise
The inverter generates high frequency noise. When designing the control panel setup, consideration must be
given to that noise. Examples of measures are given below.
• Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the
same conduit, do not run them parallel, and do not bundle them.
• Provide shielding and twisted wire for control circuit wiring.
• Separate the input (power) and output (motor) wires of the main circuit. Do not place them in the same
conduit, do not run them parallel, and do not bundle them.
• Ground the inverter ground terminals (
• Install surge suppressor on any magnetic contactor and relay coils used around the inverter.
• Install noise filters if necessary.

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
