【正文】 accidents. ? B efore inspection, perform the following steps. ① Turn off all input power to the inverter. ② Wait for at least 15 minutes and check to make sure that the charge lamp is no longer lit. ③ Use a tester that can measure DC voltages (400VDC or more), and check to make sure that the vol tage to the DC main circuits (across P(+)N()) is 45V or less. I f inspection is performed without performing these steps first, it could lead to electric shock. 14. 14. Disposal /f\ Warning See item o M andatory ? I f you throw away the inverter, have it done by a specialist in industry waste disposal*. I f you throw away the inverter by yourself, this can result in explosion of capacitor or produce noxious gases, resulting in injury. (*) Persons who specialize in the processing of waste and known as industrial waste product collectors and transporters or industrial waste disposal persons. If the collection, transport and disposal of industrial waste is done by someone who is not licensed for that j ob, it is a punishable violation of the law. (Law on Waste Disposal and Cleaning) 16. 5 Attach warning labels Shown here are examples of warning labels to prevent, in advance, accidents in relation to inverters, motors and other equipment. If the inverter has been programmed for autorestart function after momentary power failure or retry function, place warning labels in a place where they can be easily seen and read. If the inverter has been programmed for restart sequence of momentary power failure, place warning labels in a place where they can be easily s een and read. ( Example of warning label) A Warning LH: p哪 ammed Do not go near motors and equipment. Motors and equipment that have stopped temporarily after momentary power failure will restart suddenly after recovery. If the retry function has been selected, place warning labels in a location where they can be easily seen and read. ( Example of warning label) A Wing for ret「 y) Do not go near motors and equipment. M otors and equipment that have stopped temporarily after an alarm will restart suddenly after the specified time has 6 Read Check purchased product Before using the product you have purchased, check to make sure that it is exactly what you ordered. Use an inverter that conforms to the specifications of power supply and threephase induction motor being used. If the inverter being used does not conform to those specifications, not only will the threephase induction motor not rotate correctly, but it may cause serious accidents through overheating and fire.
