    FR-A800-E INSTALLATION GUIDELINE FR-A870-02300-E, 02860-E Thank you for choosing this Mitsubishi Electric Inverter. This Installation guideline and the enclosed CD-ROM give handling information and precautions for use of this product. Do not use this product until you have a full knowledge of the equipment, the safety information and the instructions.
  • Page 2 First edition For Maximum Safety Mitsubishi Electric transistorized inverters are not designed or manufactured to be used in equipment or systems in situations that can affect or endanger human life. When considering this product for operation in special applications such as machinery or systems used in passenger transportation, medical, aerospace, atomic power, electric power, or submarine repeating applications, please contact your nearest Mitsubishi Electric sales representative.
  • Page 3 A person who took a proper engineering training. Please note if you can take a proper engineering training at your local Mitsubishi Electric office. Such training may be available at your local Mitsubishi Electric office. Contact your local sales office for schedules and locations.
  • Page 4 For the installation at an altitude above 1,000 m, derate the rated current 3% per 500 m. If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi Electric product, the product will be damaged. Halogen-based materials are often included in fumigant, which is used to sterilize or disinfect wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi Electric products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging.
  • Page 5 CAUTION The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection. Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise, the life of the inverter decreases.
