AC100 HIGH-PERFORMANCE VC INVERTER MANUAL INSTALLATION AND WIRING Installation of 'Input Noise Filter' can reduce electromagnetic interference from other devices of the grid side, 'Input Noise Filter' must be as close to the inverter input terminals, at the same time, the filter must earth reliably as the inverter. earthing card. Installation 'output side noise filter' can reduce interference from radio interference and induction noise. 'Output side noise filter' must be as close to the inverter output terminals, at the same time, the filter must earth reliably as the inverter.
Control circuit cable should be shielded cables all the time; Adding zero phase reactor in power supply wire near inverter input terminal, adding zero phase reactor in the motor wire near inverter output terminal and adding zero phase reactor in control wire near inverter control terminal to efficiently reduce electromagnetic interference to the inverter. Earth Right and reliable earth is the basic condition of safe and reliable running of the product. For right earth, please read the following notice carefully. Chart 3-4: Multi AC100 Series Inverters United Earth 13 ●To avoid electric shock, earth cable should be the size as specified in the technical standards for electrical equipment.
And cable length should be as short as possible. Otherwise, leakage current of inverter would cause unstable potential of the earth terminal which is far from the earth point, and electric shock accident would happen frequently. ● Be sure to ground the ground terminal. Grounding resistance 10Ω or less, it may cause injury or death ●Earth terminal must be earth. Earth resistance must be below 10Ω. Otherwise, there is danger of injury and death. ●Please do not share earth cable with welder or other big current/pulse power equipment. Otherwise, inverter would act abnormally. ●When multi inverters are used at the same time, please do not wind the earth wire to loop-type.
Otherwise, inverter will act abnormally.
