  • Page 2 First edition For Maximum Safety Mitsubishi Electric transistorised 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 Temperature applicable for a short time, e.g. in transit. 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 Emergency stop CAUTION Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails. When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc.

  • Page 12 WIRING CAUTION To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables. Also separate the main circuit wire of the input side and the output side. After wiring, wire offcuts must not be left in the inverter. Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
  • Page 13 WIRING 3.2.3 Applied cable size Select the recommended cable size to ensure that a voltage drop will be 2% max. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency.

  • Page 18: Precautions For The Use Of The Inverter

    4 PRECAUTIONS FOR USE OF THE INVERTER The FR-A700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items. Use crimping terminals with insulation sleeve to wire the power supply and motor.
  • Page 19 PRECAUTIONS FOR USE OF THE INVERTER A motor with encoder is necessary for vector control. In addition, connect the encoder directly to the backlash-free motor shaft. (An encoder is not necessary for real sensorless vector control.) Inverter input side magnetic contactor (MC) On the inverter input side, connect a MC for the following purposes.
