SAFETY INSTRUCTIONS 1. Electric Shock Prevention WARNING While power is on or when the inverter is running, do not open the front door. You may get an electric shock. Do not run the inverter with the front door opened. Contact with the exposed high-voltage terminals or charging part of circuitry will cause an electric shock. - Page 4 4. Additional instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc.: (1) Transportation and installation CAUTION When carrying products, use correct lifting gear to prevent injury. Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the Instruction Manual.
- Page 5 (4) Operation CAUTION When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop. The [STOP] key is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately.
