CV3100 series and MINI series high performance general purpose inverter instruction manual
(5) EMI filter on the input side： The EMI filter can be used to prevent high-frequency
conductivity interference and radio-frequency interference from the inverter
power line.
(6) EMI filter on the output side ： The EMI filter can be used to prevent
radio-frequency interference noise from output side of inverter and leakage
current from conductor
(7) AC output reactor When the wire connecting inverter to motor is more than 50m,
AC output reactor had better be mounted to reduce the leakage current and
prolong the service life of motor. When installing, please consider the voltage
drop problem of AC output reactor; or the input/output voltage of inverter is
stepped up or the motor is derated to protect the motor.
(8) Safe grounding wire The inverter and motor must be earthed separately for safety
as there is leakage current in the inverter; the grounding resistance shall be less
than 10Ω. The grounding wire shall be as short as possible, and its diameter shall
be in line with the standard given in table 3-1. Only two kinds of conductors are
provided with the same metal, the value in the table can be correct, if not, the
sectional area of protective conductor is determined with the equivalent
conductive factor method and referred to table 3-1.
