earth reliably as the inverter. ● Anytime, control circuit wire should be shielded cable. ● Add zero phase reactor in power supply wire near inverter input terminal and add zero phase reactor in the motor wire near inverter output terminal to reduce electromagnetic interference to the inverter efficiently. ● Earthing Right and reliable earthing is the basic condition of safe and reliable running of the product. For right earthing, please read the following notice carefully. 6 ● In order to avoid electric shock, earthing cable should be the size as electric equipment technic standard required and cable length should be as short as possible.
Otherwise inverter leakage current will causes unstable potential of the earthing terminal which is far from the earthing point. Electric shock accident will happen frequently. ● Earth terminal must earth. Earth resistance must be below 10Ω. Otherwise there is danger of death. ● Please do not share earth cable with welder or other big current/pulse power equipment. Otherwise inverter will act abnormally. ● While multi inverters are using at the same time, please do not wind the earth wire to loop-type. Otherwise inverter will act abnormally.
