Page 3: Safety Precautions
[ Safety Precautions ] Carefully read this operation manual for correct use before installa- tion, operation, maintenance, and inspection. Thoroughly understand the machine, safety information, and precautions before use. Safety precautions are classified into "DANGER" and "CAUTION" in this manual. : Improper handling entails danger, possibly leading to death or serious DANGER... - Page 4 1. Confirmation of actual product CAUTION Do not operate the machine with a damaged inverter or an in- verter with some missing parts, otherwise injury may result. 2. Installation CAUTION Attach the machine to metal or other nonflammables, otherwise a fire may break out.
- Page 5 3. Wiring DANGER Check that the input power is OFF before wiring, otherwise an electric shock or fire may result. Be sure to install a magnetic circuit breaker (NFB), otherwise a fire may break out. Be sure to ground the grounding terminal , otherwise an electric shock or fire may result.
- Page 6 4. Operation DANGER Be sure to attach the case cover before turning the power on. Do not remove the case cover during power supply, otherwise an elec- tric shock may result. Do not operate switches with wet hands, otherwise an electric shock may result.

Set the operation stop switch on the front panel in the STOP posi- tion. 3. Set the external control terminal “RUN” in the STOP (OFF) position. 4. - Page 19 8. Precautions as to operation CAUTION 8-1 Precautions as to use (1) A high-voltage circuit is provided on the printed circuit board. Never touch it by hand. (2) The internal circuit remains charged with high voltage for some time after the power is turned off. Wait for one minute after turning off the power before inspection.
- Page 20 (12)The operator must check for the safety of the surrounding before turning on or off the power. Prevent operation by any person who is not concerned. (13) If the supply voltage drops when the power supply is interrupted instantaneously, the inverter will detect the undervoltage and shut off the output.
- Page 21 that case, use an earth leakage breaker, which is made to pre- vent high harmonics from reaching an inverter, in the system in question and other systems. (8) This inverter is for 3-phase induction motors. Do not use the inverter for single-phase motors. (9) When using the inverter for parallel operation of more than one motor, select an appropriate inverter capacity so that the total rated current will be lower than the rated current of the inverter.
