Note 4: If there are any thyristor equipments belonging to the same net, and a possibility that the surge voltage is given to the net, change
the connecting order of above Input side AC reactor and EMC filter. (Connecting order: Net -> Fuse(Circuit Breaker -> EMC filter ->
Input side AC reactor -> Inverter)
Otherwise, there is a danger of damaging inverter and/or fire.
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).
Note 3: Use 0.75mm
2
/18 AWG wire for the relay terminals (AL0, AL1 and AL2) signal wire.

Function
This is useful in suppressing harmonics induced on the power supplylines,
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.
Electrical noise interference may occur on nearby equipment such as a radio
receiver. This magnetic choke filter helps reduce radiation noise (can also be
used on output).
Reduces the conducted noise on the power supply wiring generated by the
inverter. Connect to the inverter input side.
This capacitor filter reduces radiated noise from the main power wires in the
inverter input side.
Suppresses harmonics generated by the inverter.
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 radiated noise (can also be
used on input).
This reactor reduces the vibration in the motor caused by the inverter's switching
waveforms, by smoothing the waveforms to approximate commercial power
quality. It is also useful when wiring from the inverter to the motor is more than
10m in length, to reduce harmonics.
