Note 1: Field wiring connection must be made by a UL and
Note 2: Be sure to use large wire gauges for power wiring if the distance exceeds 20m (66ft).
Note 3: Use 0.75mm2 /18 AWG wire for the relay terminals (AL0, AL1 and AL2) signal wire.

| This is useful in suppressing harmonics induced on the power supplylines, | |
Input side AC reactor | 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. | |

| |
EMC filter | Reduces the conducted noise on the power supply wiring generated by the | |
inverter. Connect to the inverter input side. | ||

Radio noise filter (Capacitor filter) | This capacitor filter reduces radiated noise from the main power wires in the | |
inverter input side. | ||

| Electrical noise interference may occur on nearby equipment such as a radio | |

| |
| This reactor reduces the vibration in the motor caused by the | |
AC reactor | 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. |
