  • Page 35: Installation Of The Inverter And Enclosure Design

    Installation of the inverter and enclosure design When designing or manufacturing an inverter enclosure, determine the structure, size, and device layout of the enclosure by fully considering the conditions such as heat generation of the contained devices and the operating environment. An inverter unit uses many semiconductor devices.
  • Page 36 NOTE • For the amount of heat generated by the inverter unit, refer to page  Humidity Operate the inverter within the ambient air humidity of usually 45 to 90% (up to 95% with circuit board coating). Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown.
  • Page 37  Vibration, impact The vibration resistance of the inverter is up to 5.9 m/s (2.9 m/s or less for the FR-F840-04320(185K) or higher) at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors, even if those vibration and impacts are within the specified values.
  • Page 38: Amount Of Heat Generated By The Inverter

     Installing the heatsink inside the enclosure When the heatsink is installed inside the enclosure, the amount of heat generated by the inverter unit is shown in the following tables. Amount of heat generated (W) Voltage Inverter model FR-F820-00046(0.75K) FR-F820-00077(1.5K) FR-F820-00105(2.2K) FR-F820-00167(3.7K) FR-F820-00250(5.5K) FR-F820-00340(7.5K)
