    ● A person who took a proper engineering training. Such training may be available at your local Mitsubishi Electric office. Contact your local sales office for schedules and locations. ● A person who can access operating manuals for the protective devices (e.g. light curtain) connect- ed to the safety control system.
  • Page 6 Electric Shock Prevention WARNING: ● While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock. ● Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.
  • Page 7 Fire Prevention CAUTION: ● Mount the inverter to incombustible material. Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mount- ing it to or near combustible material can cause a fire. ●...
  • Page 8 Additional Instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc. Transportation and installation CAUTION: ● Any person who is opening a package using a sharp object, such as a knife and cutter, must wear gloves to prevent injuries caused by the edge of the sharp object. ●...
  • Page 9 Wiring CAUTION: ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi. These devices on the inverter output side may be overheated or burn out. ● The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is maintained.
  • Page 10 CAUTION: ● The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection. ● Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
  • Page 11 Emergency stop CAUTION: ● Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails. ● When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc.
