  • Page 30 Mounting Installation NOTE When encasing multiple inverters, install them in parallel as a cooling measure. Leave enough clearances around the inverter (refer to page 2-11). Fig. 2-8: Good heat dissipation is achieved through the vertical alignment of the frequency inverter, the side-by-side mounting and maintenance of minimum clearances.

  • Page 31: Enclosure Design

    Temperature applicable for a short time, e.g. in transit. Temperature The permissible ambient temperature of the inverter FR-E700 SC is between 10 and +50 °C. Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following meas- ures so that the ambient temperature of the inverter falls within the specified range.
  • Page 32 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 33 Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break. ● Countermeasures – Provide the enclosure with rubber vibration isolators. – Strengthen the structure to prevent the enclosure from resonance. – Install the enclosure away from sources of vibration. FR-E700 SC EC/ENE 2 - 9...
  • 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 (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 35: Inverter Placement

    Mount the inverter on a wall as specified. Do not mount it horizontally or any other way. Above the inverter Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be heat resistant. FR-E700 SC EC/ENE 2 - 11...
  • 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 temperatures in the top inverters, causing inverter failures.

  • Page 38 Inverter and peripheral devices Wiring NOTES The life of the inverter is influenced by ambient temperature. The ambient temperature should be as low as possible within the permissible range. Especially when mounting the inverter inside an enclosure, take cautions of the ambient temperature. (Refer to section 2.4.2.) Wrong wiring might lead to damage of the inverter.

  • Page 39: Peripheral Devices

    When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), dam- age to internal parts of the inverter, etc. Identify the cause of the trip, then remove the cause and power on the breaker. FR-E700 SC EC/ENE 3 - 3...
