7.3 Selection of Peripheral EMC Devices
7.3.1 Installation of EMC Input Filter on Power Input Side
An EMC filter installed between the AC drive and the power supply can not only restrict
the interference of electromagnetic noise in the surrounding environment on the AC drive,
but also prevents the interference from the AC drive on the surrounding equipment.
The SSI700 series AC drive satisfies the requirements of category C2 only with an EMC
filter installed on the power input side. The installation precautions are as follows:
•
Strictly comply with the ratings when using the EMC filter. The EMC filter is
category I electric apparatus, and therefore, the metal housing ground of the filter should
be in good contact with the metal ground of the installation cabinet on a large area, and
requires good conductive continuity. Otherwise, it will result in electric shock or poor EMC
effect.
•
The ground of the EMC filter and the PE conductor of the AC drive must be tied
to the same common ground. Otherwise, the EMC effect will be affected seriously.
•
The EMC filter should be installed as closely as possible to the power input
side of the AC drive.
The following table lists the recommended manufacturers and models of EMC filters for
the SSI700 series AC drive. Select a proper one based on actual requirements.
7.3.2 Installation of AC Input Reactor on Power Input Side
An AC input reactor is installed to eliminate the harmonics of the input current. As an
optional device, the reactor can be installed externally to meet strict requirements of an
application environment for harmonics. The following table lists the recommended
manufacturers and models of input reactors.
7.3.3 Installation of AC Output Reactor on Power Output Side
Whether to install an AC output reactor on the power output side is dependent on the
actual situation. The cable connecting the AC drive and the motor should not be too long;
capacitance enlarges when an over-long cable is used and thus high-harmonics current
may be easily generated.
If the length of the output cable is equal to or greater than the value in the following table,
install an AC output reactor on the power output side of the AC drive.
