Chapter 2 Installation and Wiring 2.1 Installation CAUTION ! - Install the inverter on a non-flammable surface, e.g., metal. Otherwise, you run the risk of fire. - Do not place flammable materials near the installed inverter. Otherwise, you run the risk of fire. - When carrying the inverter, do not hold its top cover.
Chapter 2 Installation and Wiring 2.1.1 Precautions for installation (1) Transportation The inverter uses plastic parts. When carrying the inverter, handle it carefully to prevent damage to the parts. Do not carry the inverter by holding the front or terminal block cover. Doing so may cause the inverter to fall.
Page 16
Chapter 2 Installation and Wiring (6) Installation method and position Install the inverter vertically and securely with screws or bolts on a surface that is free from vibrations and that can bear the inverter weight. If the inverter is not installed vertically, its cooling performance may be degraded and tripping or inverter damage may result.
Chapter 2 Installation and Wiring (9) Reduction of enclosure size If you mount the inverter inside an enclosure such that the heat sink of the inverter is positioned outside the enclosure, the amount of heat produced inside the enclosure can be reduced and likewise the size of the enclosure.
Chapter 2 Installation and Wiring 2.2 Wiring ! WARNING - Be sure to ground the inverter. Otherwise, you run the risk of electric shock or fire. - Commit wiring work to a qualified electrician. Otherwise, you run the risk of electric shock or fire. - Before wiring, make sure that the power supply is off.

- This inverter does not support a single-phase power supply but supports only a three-phase power supply. If you need to use a single-phase power input, contact your supplier or local Hitachi Distributor. - Do not operate the inverter with an phase loss power input, or it may be damaged.
Page 24
Chapter 2 Installation and Wiring - When connecting multiple motors to the inverter, connect a thermal relay to the inverter output circuit for each motor. - The RC rating of the thermal relay must be 1.1 times as high as the rated current of the motor. The thermal relay may go off too early, depending on the cable length.
