    Transportation Precautions Caution Do not hold by front cover or panel , instead, hold by the radiation fin (heat sink) while transporting the product. Doing so may result in injury. Caution Do not pull on the cables. Doing so may result in damage to the product or malfunc- tion.

  • Page 8

    Caution Install external breakers and take other safety measures against short-circuiting in external wiring. Not doing so may result in fire. Caution Confirm that the rated input voltage of the Inverter is the same as the AC power sup- ply voltage. An incorrect power supply may result in fire, injury, or malfunction. Caution Connect the Braking Resistor and Braking Resistor Unit as specified in the manual.

    Chapter 2 Design D Installing a Noise Filter on the Power Supply Side The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from the Inverter to the power line and adversely affect other devices in the vicinity. It is recommended that a Noise Filter be installed at the Power Supply to minimize this noise transmission.

    Chapter 2 Design D Installing a Thermal Relay The Inverter has an electronic thermal protection function to protect the motor from overheating. If, how- ever, more than one motor is operated with one inverter or a multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set n037 to 2 (no thermal protection).

    Chapter 2 Design Note To satisfy LVD requirements, the Inverter must be protected with a line breaker in case a short-cir- cuiting accident occurs. When using a single line breaker to be shared with other Inverters or devices, make sure that the Inverters and devices will be fully protected if there is a one-point short-circuit, otherwise the Inverters and devices may be damaged.

    Chapter 11 Using the Inverter for a Motor H Using Inverter for Existing Standard Motor When a standard motor is operated with the Inverter, a power loss is lightly higher than when operated with a commercial power supply. In addition, cooling effects also decline the low-speed range, resulting in an increase in the motor tem- perature.

  • Page 339

    Chapter 11 Using the Inverter for a Motor D Noise Noise is almost the same as when the motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is operated at a speed higher than the rated speed (60 Hz). H Using Inverter for Special Motors D Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors.

    Chapter 11 Using the Inverter for a Motor H Motor Burnout Caused by Insufficient Dielectric Strength of Each Phase of Motor Surge occurs among the phases of the motor when the output voltage is switched. If the dielectric strength of each phase of the motor is insufficient, the motor may burn out. The dielectric strength of each phase of the motor must be higher than the maximum surge voltage.
