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.
Page 23: Precautions For Installation
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. Do not install and operate the inverter if it is damaged or its parts are missing.
Page 24 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.
Page 25: Backing Plate
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. Mounting the inverter in an enclosure with the heat sink positioned outside requires an optional dedicated special metal fitting.

Page 283 Appendix Upgrading from the SJ300 Series The SJ300/SJ700 series inverter is upwardly compatible with the SJ700D-3 series inverter. Therefore, you can: - mount the control circuit terminal block board of the SJ300 series in the SJ700 series without removing the connected cables, - copy the parameter settings from the SJ300 series into the SJ700 series, and - use the option boards mounted in the SJ300 series for the SJ700 series without removing the connected cables.
Page 284 Appendix (2) Copying the parameter settings If you use an optional remote operator (WOP, SRW-OJ or SRW-OEX), you can copy (import) the parameter settings from the SJ300/SJ700 series into the SJ700D-3 series. Note, however, that you cannot copy the parameter settings from the SJ700D-3 series to the SJ300/SJ700 series because the SJ700 series has many new functions and additional parameters.
