  • Page 5: Safety Instructions

    Thank you for choosing this Mitsubishi inverter. This instruction manual provides instructions for advanced use of the FR-F700 series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this instruction manual to use the equipment to its optimum. Safety instructions Do not attempt to install, operate, maintain or inspect the inverter until you have read through this instruction manual carefully and can use the equipment correctly.
  • Page 6 ● Do not replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on. ● Do not touch the printed circuit board or handle the cables with wet hands. You may get an electric shock. MITSUBISHI ELECTRIC...
  • Page 7 Fire prevention CAUTION: ● Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mounting it to or near combustible material can cause a fire. ● If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire.
  • Page 8 ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi. ● The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is maintained. MITSUBISHI ELECTRIC...
  • Page 9 Operation WARNING: ● When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop. ● Since pressing STOP/RESET key may not stop output depending on the function setting status, provide a circuit and switch separately to make an emergency stop (power off, mechanical brake operation for emergency stop, etc.).
  • Page 10 ● When the protective function is activated (i. e. the frequency inverter switches off with an error message), take the corresponding corrective action as described in the inverter manual, then reset the inverter, and resume operation. MITSUBISHI ELECTRIC...
  • Page 11 Maintenance, inspection and parts replacement CAUTION: ● Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure. Disposing the inverter CAUTION: ● Treat as industrial waste. General instructions Many of the diagrams and drawings in instruction manuals show the inverter without a cover, or partially open.

I000997E Fig. 2-8: Installation on the panel The inverter consists of precision mechanical and electronic parts.
  • Page 31: Enclosure Design

    Installation Enclosure design Enclosure design When an inverter enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the enclosure structure, size and equipment layout. The inverter unit uses many semiconductor devices.
  • Page 32 Enclosure design Installation Humidity Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high hu- midity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. The insulation distance specified in JEM1103 "Control Equipment Insulator"...
  • Page 33 Installation Enclosure design Explosive, flammable gases As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure. In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and has passed the specified tests. This makes the enclosure itself expensive (including the test charges).
  • Page 34 Enclosure design Installation 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 dis- sipated to keep the in-enclosure temperature lower than the permissible temperatures of the in- enclosure equipment including the inverter.
  • Page 35: Inverter Placement

    Installation Enclosure design 2.4.2 Inverter placement Clearances around the inverter Always observe the specified minimum clearances to ensure good heat dissipation and ade- quate accessibility of the frequency inverter for servicing. Ambient temperature and humidity Clearances (side) Clearances (front) Measurement 01160 or less 01800 or more position...
  • Page 36 Enclosure design Installation Arrangement of multiple inverters When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the 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 tem- peratures in the top inverters, causing inverter failures.
  • Page 37: Heatsink Protrusion Attachment (fr-a7cn)

    Installation Enclosure design 2.4.3 Heatsink protrusion attachment (FR-A7CN) When encasing the inverter in an enclosure, the generated heat amount in an enclosure can be greatly reduced by installing the heatsink portion of the inverter outside the enclosure. When in- stalling the inverter in a compact enclosure, etc., this installation method is recommended. For the FR-F740-00023 to 03610, a heatsink can be protruded outside the enclosure using a heatsink protrusion attachment (FR-A7CN).
  • Page 38 Enclosure design Installation Installation of the inverter Push the inverter heatsink portion outside the enclosure and fix the enclosure and inverter with upper and lower installation frame. * For the FR-F740-05470 or more, there are finger guards behind the enclosure. Therefore, Enclosure the thickness of the panel should be less than 10mm and also do not place anything around...
  • Page 39: Wiring

    Wiring Inverter and peripheral devices Wiring Inverter and peripheral devices 3-phase AC power supply Use within the permissible power supply specifications of the inverter. (Refer to Appendix A.) Inverter (FR-F700 EC) The life of the inverter is influenced by ambient temperature.
  • Page 40 Inverter and peripheral devices Wiring NOTES Do not install a power factor correction capacitor or surge suppressor on the inverter output side. This will cause the inverter to trip or the capacitor and surge suppressor to be dam- aged. If any of the above devices are connected, immediately remove them. Electromagnetic Compatibility Operation of the frequency inverter can cause electromagnetic interference in the input and output that can be propagated by cable (via the power input lines), by wireless radiation to...

  • Page 44 Terminal connection diagram Wiring NOTES To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables. 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. When drilling mounting holes in an enclosure etc., take care not to allow chips and other for- eign matter to enter the inverter.

Assumes that the ambient temperature is 50°C or less and the wiring distance is 20m or less. For the 01800 or more, the recommended cable size is that of LMFC (heat resistant flexible cross-linked polyethylene insulated cable) with continuous maximum permissible tempera- ture of 95°C.

Since voltages and currents in the primary and secondary side of the inverter include harmonics, different meters indicate different measured values. When the inverter-to-motor wiring length is large, especially in the 400V class, large-capacity models, the meters and CTs may generate heat due to line-to-line leakage current.
