2.4.1 Connection of drive and option
(1) Between power grid and drive,
Breaking device like isolating switch shall
be installed for Human safety and compulsive
power cutting during
Maintaining the device
(2) The supply circuit of drive must be
Mounted With the fuse or circuit breaker
with over current Protection, to avoid the
spread of fault.
(3) When the power supply quality of
Power Grid is not quite high, an AC
input reactor shall Be mounted
additionally. The AC reactor also Can
improve the power factor of input side
(4) The contactor is only for control
of power supply
(5) EMI filter on the input side: The EMI can be used
to prevent high-frequency conductivity and radio-frequency
Interference from the drive 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 drive and
leakage current from conductor
(7) Ac output reactor:
