6.3.2 Installation of AC 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 hormonics. The following
table lists the recommended manufacturers and models of input reactors.

6.3.3 Installation of AC 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.
