    As our measure, it is recommended that DC reactors (DCRs) authorized in this manual be con- nected to the series of inverters. When using DCRs not authorized in this manual, however, consult your GMTCNT representative for the detailed specifications.

  • Page 8: Safety Precautions

    „ Safety precautions Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance and inspection. Ensure you have sound knowledge of the device and familiarize yourself with all safety information and precautions before proceeding to operate the inverter. Safety precautions are classified into the following two categories in this manual.
  • Page 9 • Do not support the inverter by its terminal block 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. Otherwise, a fire or an accident might result.
  • Page 10 • Generally, control signal wires are not reinforced insulation. If they accidentally touch any of live parts in the main circuit, their insulation coat may break for any reasons. In such a case, an extremely high voltage may be applied to the signal lines. Make a complete remedy to protect the signal line from contacting any hot high voltage lines.
  • Page 11 • If you enable the "restart mode after momentary power failure" (Function code F14 = 4 or 5), then the inverter automatically restarts running the motor when the power is recovered. (Design the machinery or equipment so that human safety is ensured after restarting.) •...
  • Page 12 Disposal • Handle the inverter as an industrial waste when disposing of it. Otherwise injuries could occur. Others • Never attempt to modify the inverter. Doing so could cause electric shock or injuries. GENERAL PRECAUTIONS Drawings in this manual may be illustrated without covers or safety shields for explanation of detail parts.
