  • Page 32: 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 uses many semiconductor devices.

  • Page 33: High Altitude

    NOTE • For the amount of heat generated by the inverter unit, refer to page  Humidity Normally operate the inverter within the ambient air humidity of 45% to 95%. 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. The humidity conditions for the insulation distance defined in JEM 1103 standard "Insulation Distance from Control Equipment"...

  • Page 34: Amount Of Heat Generated By The Inverter

     Vibration, impact The vibration resistance of the inverter is as follows: the maximum amplitude is 0.075 mm (frequency range: 10 to 57 Hz), and the maximum acceleration speed is 1G (frequency range: 57 to 150 Hz). Subjecting the product to vibration and impacts over a long period of time may loosen the structure and cause poor contacts of connectors, even if those vibration and impacts are within the specified values.

  • Page 35: Cooling System Types For Inverter Enclosure

    2.3.3 Cooling system types for inverter enclosure From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the permissible temperatures of the in-enclosure equipment including the inverter.

  • Page 36: Inverter Installation
