<Note>
Field wiring connection must be made by a UL listed and CSA certified, closed-loop
terminal connector sized for the wire gauge involved. Connector must be fixed using
the crimp tool specified by the connector manufacturer.
Be sure to consider the capacity of the circuit breaker to be used.
Be sure to use bigger wires for power lines if the distance exceeds 20m.

This is useful when harmonic suppression measures must be
taken. when the main power voltage unbalance rate exceeds
3% and the main power capacity exceeds 500kVA, or when
a sudden power voltage variation occurs. It also helps to
improve the power factor.
Reduces the conductive noise on the main power wires
generated from the main power supply. Connect to the
inverter primary side(input side).
This is installed between the inverter and the motor to reduce
noise radiated from the main the control power wiring. It is
useful for reducing radio-wave disturbance in a radio or TV
set and for preventing malfunction of measuring instruments
or sensors.
Vibration may increases when driving a general-purpose
motor with an inverter as compared with operation on
commercial power. Connecting this reactor between the
inverter and the motor allows reduction of motor pulsation.
When the wirung between the inverter and the motor is 10m
or more, inserting the reactor prevents thermal relay malfun-
ction caused by harmonics resulting from incerter switching.
A current sensor can be used instead of the thermal relay
