3.4.1 Connection between inverter and fitting parts
(1) Must assemble disjunction device such as isolation switch etc. between
powersource and the inverter to assure personal safety when repairing the inverter
and needing compulsory power off.
(2) Power supply loop must have breaker or
fuse with over current protection function to
avoid malfunction expanding caused by failure
of after device.
(3) AC input reactor
If high-order harmonics between inverter and
Power supply is biggish which can’t fulfil
system requirement, or need to improve input
side power factor, AC input reactor is needed.
(4) Magnetic control conductor only be applied
to power supply control and don’t apply
magnetic control conductor to controlling on/off
of the inverter.
(5) Input side EMI filter
Can use EMI filter to inhibit high-frequency
conduction disturbance and emission
disturbance from inverter power supply wire.
(6) Output side EMI filter
Can use EMI filter to inhibit emission disturbance
noise and wire leakage current from output side.
(7) AC output reactor
Advise assembling AC outputreactor to avoid
motor insulation damage, too large over current
and inverter frequent protection when connecting wire from inverter to motor
