Contact your local sales office for schedules and locations.
  • Page 3 Electric Shock Prevention WARNING  While the inverter power is ON, do not remove the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed, as accidental contact with exposed high- voltage terminals and internal components may occur, resulting in an electrical shock.
  • Page 4 Injury Prevention CAUTION  The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise an explosion or damage may occur.  The cables must be connected to the correct terminals. Otherwise an explosion or damage may occur.

Halogen-based materials are often included in fumigant, which is used to sterilize or disinfest wooden packages.
  • Page 6 WARNING Usage  Stay away from the equipment after using the retry function in this product as the equipment will restart suddenly after the output shutoff of this product.  Since pressing the STOP/RESET key may not stop output depending on the function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.
  • Page 7 CAUTION Usage  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. Doing so may shorten the life of this product.

  • 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 unit uses many semiconductor devices.
  • Page 33  Sudden temperature changes • Select an installation place where temperature does not change suddenly. • Avoid installing the inverter near the air outlet of an air conditioner. • If temperature changes are caused by opening/closing of a door, install the inverter away from the door. NOTE •...
  • Page 34  High altitude Use the inverter at an altitude of within 2500 m. For use at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude. If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric strength.
  • Page 35 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 2.3.4 Inverter installation  Inverter placement Fix six positions for the FR-F860-02890 or higher. • Install the inverter on a strong surface securely with screws. • Leave enough clearances and take cooling measures. • Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity. •...
  • Page 37  Arrangement of multiple inverters When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the right figure (a). When it is inevitable to arrange them vertically to minimize space, take such measures as to provide guides since heat from the bottom inverters can increase the temperatures in the top inverters, causing inverter failures.
  • Page 38 2.3.5 Protruding the heat sink through a panel When encasing the inverter of the FR-F860-02890 or higher to an enclosure, the heat generated in the enclosure can be greatly reduced by protruding the heat sink of the inverter. When installing the inverter in a compact enclosure, etc., this installation method is recommended. ...

  • Page 74  Countermeasures • Use Pr.9 Electronic thermal O/L relay. • If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting. Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.
  • Page 75  Techniques to reduce electromagnetic noises that are radiated by the inverter to cause the peripheral devices to malfunction (EMI countermeasures) Inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and inverter main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.

  • Page 79  Handling of the manual contactor on the inverter's output side A PM motor is a synchronous motor with high-performance magnets embedded inside. High-voltage is generated at the motor terminals while the motor is running even after the inverter power is turned OFF. In an application where the PM motor is driven by the load even after the inverter is powered OFF, a low-voltage manual contactor must be connected at the inverter's output side.

  • Page 84: Failsafe System Which Uses The Inverter

    Although Mitsubishi Electric assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
  • Page 85  Checking by the output of the inverter fault signal... (a) When the inverter's protective function activates and the inverter trips, the Fault (ALM) signal is output. (Fault (ALM) signal is assigned to terminal A1B1C1 in the initial setting). With this signal, check that the inverter operates properly. In addition, negative logic can be set.
  • Page 86  Backup method outside the inverter Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure status of the inverter itself. For example, if an inverter CPU fails in a system interlocked with the inverter's fault, start, and RUN signals, no fault signal will be output and the RUN signal will be kept ON because the inverter CPU is down.
