  • Page 5: Safety Instructions

    ● 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 Electric product, the product will be damaged. Halogen-based materials are often in- cluded in fumigant, which is used to sterilize or disinfect wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi Electric prod- ucts, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging.
  • Page 9 CAUTION: ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi Electric. 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 Test operation and adjustment CAUTION: ● Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions. 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.

It may also cause a malfunction or fault of the equipment connected ON the inverter output side.
  • Page 72: Earthing (Grounding) Precautions

    Main circuit terminals Installation and wiring 2.5.4 Earthing (grounding) precautions Always earth (ground) the motor and inverter. Purpose of earthing (grounding) Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use. An electrical circuit is usually insulated by an insulating material and encased. However, it is impos- sible to manufacture an insulating material that can shut off a leakage current completely, and actu- ally, a slight current flows into the case.
