    Thank you for choosing this Mitsubishi inverter. This instruction manual provides instructions for advanced use of the FR-D700 SC series in- verters. 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

    Electric shock prevention WARNING: ● While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock. ● Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.

  • Page 7

    Fire prevention CAUTION: ● Mount the inverter to incombustible material. 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. ●...

    Additional instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc. Transport and installation CAUTION: ● Transport the product using the correct method that corresponds to the weight. Failure to observe this could lead to injuries. ●...

  • Page 9

    Trial run CAUTION: ● Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions. Operation WARNING: ● When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.

  • Page 10

    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.

  • Page 11

    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. Never run the inverter in this status. Always replace the cover and follow this in- struction manual when operating the inverter.

  • 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) x = Measurement 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.

    Inverter and peripheral devices Wiring NOTES The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure (refer to section 2.4.2). Wrong wiring might lead to damage of the inverter.

    Main circuit connection Wiring Cables and wiring length 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 45

    Wiring Main circuit connection CAUTION: ● Tighten the terminal screw to the specified torque. A screw that has been tightened too loosely can cause a short circuit or malfunction. A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.

    Main circuit connection Wiring Notes on earthing CAUTION: Leakage currents flow in the inverter or the EMC filter respectively. To prevent an electric shock, the inverter, input filter and motor must be earthed. This inverter must be earthed. Earthing must conform to the requirements of national and local safety regulations and electrical codes (JIS, NEC section 250, IEC 536 class 1 and other applicable standards).

  • Page 47

    Wiring Main circuit connection Total wiring length The maximum possible length of the motor cables depends on the capacity of the inverter and the selected carrier frequency. The lengths in the following tables are for unshielded cables. When shielded cables are use di- vide the values listed in the table by 2.

  • Page 48

    Main circuit connection Wiring NOTES Note that the motor windings are subjected to significantly higher loads when the motor is operated by inverter than with normal mains operation. The motors must be approved for inverter operation by the manufacturer (refer also to section 3.7.4). Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit function, or stall prevention function or a mal-...

    Precautions for use of the inverter Operation ● Do not use the inverter input side magnetic contactor to start/stop the inverter. Since repeated inrush currents at power ON will shorten the life of the converter circuit (switching life is about 1,000,000 times), frequent starts and stops of the MC must be avoided.

    Operation Precautions for use of the inverter ● Handling of inverter output side magnetic contactor Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the magnetic contactor is turned ON while the inverter is operating, overcurrent protection of the inverter and such will activate.
