  • Page 5 Thank you for choosing this Mitsubishi inverter. This instruction manual provides instructions for advanced use of the FR-E700SC series inverters. In- correct handling might cause an unexpected fault. Before using the inverter, always read this instruc- tion 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.). Mount- ing it to or near combustible material can cause a fire. ●...

  • Page 27: Enclosure Design

    Installation Enclosure design Enclosure design When an inverter enclosure is to be designed and manufactured, heat generated by contained equip- ment, 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 de- vices.
  • Page 28 Enclosure design Installation Humidity Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity 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 29 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 30 Enclosure design Installation Cooling system types for inverter enclosure From the enclosure that contains the inverter, the heat of the inverter and other equipment (trans- formers, 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 32 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 temperatures in the top inverters, causing inverter failures.
