possible. Meantime, the filter must earth reliably as the inverter.
● Build noise filter at the output side to reduce radio interference and inductive disturbance. The
noise filter must be as close to the inverter output terminal as possible. Meantime, the filter must
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.
● 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.
