A whistling noise in the Fuji Electric series motor from the start of operation can be caused by using a general-purpose motor with an inverter, as the motor noise level is higher than when using a commercial power supply. Increasing the carrier frequency of the inverter can help reduce the noise.

  • Page 3: Preface

    Preface Thank you for purchasing our FRENIC-Lift series of inverters. FRENIC-Lift is an inverter designed to drive a three-phase induction motor (hereafter called an induction motor) and a three-phase permanent magnet synchronous motor (hereafter called a synchronous motor) for exclusively controlling elevating machinery.

  • Page 17 When employing external cooling At the shipment time, the inverter is set up for mount inside your equipment or enclosure so that cooling is done all internally. To improve cooling efficiently, you can take the heat sink out of the equipment or the enclosure (as shown on the right) so that cooling is done both internally and externally (this is called "external cooling").
  • Page 18 1) Remove all of the base fixing screws from the top and bottom of the inverter. Also remove the case fixing screws from the top. (The case fixing screws are not necessary in external cooling. Store them for future use. On the bottom are no case fixing screws.) 2) Secure the top mounting base to the center of the inverter with the base fixing screws, using case fixing screw holes.
  • Page 19 (3) Mounting direction Horizontal layout is recommended when two or more inverters are to be installed in an equipment or enclosure. As long as the ambient temperature is 40°C or lower, inverters may be mounted side-by-side without any gap between them. If it is necessary to mount the inverters vertically, install a partition plate or the like between the inverters so that any heat radiating from an inverter will not affect the one/s above.

  • Page 33: Wiring For Control Circuit Terminals

    2.3.7 Wiring for control circuit terminals In general, sheaths and covers of the control signal cables and wires are not specifically designed to withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal cable or wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath or the cover might break down, which would expose the signal wire to a high voltage of the main circuit.
