  Index to Warnings and Cautions in This Manual Installation — Cautions for Mounting Procedures CAUTION: The inverter is shipped with a plastic cover over the top vent grill. REMOVE this cover after the installation is complete. Operation with this cover in place will not allow proper cooling, and damage to the inverter may result.

  Otherwise, there is the possibility of damage to the inverter and the danger of fire. CAUTION: Be sure not to connect an AC power supply to the output terminals. Otherwise, there is the possibility of damage to the inverter and the danger of injury and/or fire.
• Page 7
  CAUTION: Remarks for using ground fault interrupter breakers in the main power supply: Adjustable frequency inverters with CE-filters (RFI- filter) and shielded (screened) motor cables have a higher leakage current toward Earth GND. Especially at the moment of switching ON this can cause an inadvertent trip of ground fault interrupters.

  (be sure to design the machine so that safety for personnel is secure even if it restarts.) Otherwise, it may cause injury to personnel. WARNING: If the power supply is cut OFF for a short period of time, the inverter may restart operation after the power supply recovers if the Run command is active.
• Page 9
  viii WARNING: Be sure not to touch the inside of the energized inverter or to put any conductive object into it. Otherwise, there is a danger of electric shock and/or fire. WARNING: If power is turned ON when the Run command is already active, the motor will automatically start and injury may result.

• Page 10: General Warnings And Cautions

  Warnings and Cautions for Troubleshooting and Maintenance WARNING: Wait at least five (5) minutes after turning OFF the input power supply before performing maintenance or an inspection. Other- wise, there is the danger of electric shock. WARNING: Make sure that only qualified personnel will perform maintenance, inspection, and part replacement.

  Introduction to Variable-Frequency Drives The Purpose of Motor Speed Control for Industry Hitachi inverters provide speed control for 3-phase AC induction motors. You connect AC power to the inverter, and connect the inverter to the motor. Many applications benefit from a motor with variable speed, in several ways: •…

  From this it mathematically calculates two vector currents. One vector is related to motor flux current, and the other to motor torque current. The ability to separately control these two vectors is what allows the SJ100 to deliver extraordinary low-speed performance and speed control accuracy.
• Page 39
  The Hitachi inverter is a rugged and reliable device. The intention is for the inverter to assume the role of controlling power to the motor during all normal operations. There- fore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop).

WARNING: If the power supply is cut OFF for a short period of time, the inverter may restart operation after the power supply recovers if the Run command is active. If a restart may pose danger to personnel, so be sure to use a lock-out circuit so that it will not restart after power recovery.
