Note 1: Field wiring connection must be made by a UL and c-UL listed closed-loop terminal connector sized for
the wire gauge involved.
Connector must be fixed using the crimping tool specified by the connector manufacturer.
Note 2: Be sure to use large wire gauges for power wiring if the distance exceeds 20m (66ft).

Function
This is useful in suppressing harmonics induced on the power sup-
ply lines, or when the main power voltage imbalance exceeds 3%
(and power source capacity is more than 500kVA), or to smooth out
line fluctuations. It also improves the power factor.
Reduces the conducted noise on the power supply wiring generat-
ed by the inverter. Connect to the inverter input side.
Electrical noise interference may occur on nearby equipment such
as a radio receiver. This magnetic choke filter helps reduce radiat-
ed noise (can also be used on output).
This capacitor filter reduces radiated noise from the main power
wires in the inverter input side.
Suppresses harmonics generated by the inverter.
This is useful for increasing the inverter's control torque for high
duty-cycle (on-off) applications, and improving the decelerating
capability.
Reduces radiated noise from wiring in the inverter output side.
Electrical noise interference may occur on nearby equipment such
as a radio receiver. This magnetic choke filter helps reduce radiat-
ed noise (can also be used on input).
This reactor reduces the vibration in the motor caused by the inver-
ter's switching waveforms, by smoothing the waveforms to approxi-
mate commercial power quality. It is also useful when wiring from
the inverter to the motor is more than 10m in length, to reduce har-
monics.
Sine wave shaping filter for the output side.
