  • Page 3 2. Fire Prevention Mount the inverter on an incombustible surface. Installing the inverter directly on or near a combustible surface could lead to a fire. If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire.
  • Page 4 (2) Wiring Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter (option FR-BIF(-H)) or surge suppressor to the output of the inverter. The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor.
  • Page 5 Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected. Take measures to suppress harmonics. Otherwise power supply harmonics from the inverter may heat/damage the power capacitor and generator. When a 400V class motor is inverter-driven, please use an insulation-enhanced motor or measures taken to suppress surge voltages.

    3.1.2 To know the operating status at the occurrence of alarm (only when FR-PU04 is used) When any alarm has occurred, the display automatically switches to the indication of the corresponding protective function (error). By pressing the resetting the inverter, the display shows the output frequency. In this way, it is possible to know the running frequency at the occurrence of the alarm.

    For repeated duty, allow time for the inverter and motor to return to or below the temperatures under 100% load. *4. The maximum output voltage does not exceed the power supply voltage. You can set the maximum output voltage to any value below the power supply voltage. However, the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply.
