AC input reactor is mainly used to reduce the harmonics in the input current. As optional device.
When the application environment has high requirements about harmonic, an external reactor
can be installed.
4.3.5 Installation of AC output reactor on frequency inverter output
Whether to install AC output reactor on the output side of the frequency inverter depends on the
actual situation. The transmission line between the frequency inverter and the motor should not
be too long. Distributed capacitance is large when the cable is too long and it will generate
high-harmonic current easily.
When the cable length is equal to or greater than or the value in the table below, AC output
reactor installed near the output of the frequency inverter is needed:

4.3.6 Installation of external DC reactor
The SV600 series frequency inverter (Power ≤ 75KW) uses a separate wooden case package
when the external DC reactor is shipped. When the user installing it, the short-circuit copper bar
between the terminal + 2 and + 1 of the frequency inverter main circuit should be removed
firstly. Please install the DC reactor between + 2 and + 1, and the terminals have no polarity.
After the DC reactor installed well, the short-circuit copper bar b 2 and + 1 no needed.
Note: special requirements can be customized non-standard.
4.3.7 Shielded cable

Requirements for shielded cables
In order to meet the EMC requirements of CE marking, shielded cables must be used. There are
three phase conductor shielded cables and four phase conductor shielded cables. If the
conductive properties of the shield cannot satisfy the requirements, a separate PE wire is needed.
One wire of the four phase conductors shielded cable can be used as PE wire as shown in
