  • Page 3: Safety Precautions

    Preface Thank you for purchasing our FRENIC-HVAC series of inverters. This product is designed to drive a three-phase induction motor. This instruction manual provides only minimum requisite information for wiring and operation of the product. Read through this manual before use.
  • Page 4 • Do not support the inverter by its front cover during transportation. Doing so could cause a drop of the inverter and injuries. • Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.
  • Page 5 • In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath might break down, which would expose the signal wire to a high voltage of the main circuit.
  • Page 6 Design the machinery or equipment so that human safety is ensured after restarting. • If the user configures the function codes wrongly without completely understanding this Instruction Manual and the FRENIC-HVAC User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
  • Page 7 Maintenance and inspection, and parts replacement • Before proceeding to maintenance or inspection, turn OFF the power and wait at least 10 minutes. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).
