					Optional external devices
No.		Device			Function and purpose
	Input AC reactor		Used to improve the input power factor, reduce the harmonics, and suppress external
			surge on the inverter power source side. Install when the power capacity is 500 kVA or
			more and 10 times or more than the inverter capacity or when a distorted wave genera-
			tion source such as a thyristor unit or a large-capacity inverter is connected in the same
			distribution system.

	DC reactor		Improves the power factor more than the input reactor. When the facility applying the
			inverter requires high reliability, it is recommended to use the DC reactor with an input re-
			actor effective for external surge suppression.
(2)			* An inverter unit of 200V-3.7kW or less is connected to a reactor selected on page J-8, 9
				to conform “Guides of limits for harmonics current emissions on general purpose
				inverter having an input current up to and including 20A per phase” by the Japan Elec-
				trical Manufacturers’ Association.
		High-attenuation filter	These types of filters are not necessary because all single-phase 200V or 3-phase 400V
