Device
Function and purpose
(1)
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 200 kVA or
more and 10 times or more than the inverter capacity or when a distorted wave
generation source such as a thyristor unit or a large-capacity inverter is connected in the
same distribution system.

(2)
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
reactor effective for external surge suppression.
* 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
Electrical Manufacturers' Association.

High-attenuation filter
(LC filter) NF type
manufactured by
Soshin Electric Co.,
Ltd.
These types of filters are not necessary because all single-phase 200V or 3-phase 400V
models have a built-in EMI noise filter, conforming to Class A, as standard. But install
these filters if necessarily of noise reduction move and more.
•
Effective to prevent interference in audio equipment used near the inverter.
•
Install on the input side of the inverter.
•
Provided with wide-range attenuation characteristics from AM radio bands to near
10MHz.
•
Use when equipment readily affected by noise is installed in the peripheral area.
(4)
Zero-phase reactor
(inductive filter) ferrite
core-type
by Soshin Electric
Co., Ltd.
•
Effective to prevent interference in audio equipment used near the inverter.
•
Effective in noise reduction on both input and output sides of the inverter.
•
Provided with attenuation characteristics of several dB in frequencies from AM radio
bands to 10MHz.
•
For noise countermeasures, insert on the secondary side of the inverter.

Foot-mounted noise
filter
High-attenuation EMI noise filter requiring only small space; mounted on the rear side of
the inverter. The installation of this filter reduces transmission noise below the level re-
quired for the inverter to comply with the following standard.
3-phase 200V model
: CISPR/B/276/DC Class A Group 1
(Length of motor connecting cable: Max. 5 m)
1-phase 200V/3-phase 400V models
: EN55011 Class B Group 1
(Length of motor connecting cable: Max. 20 m)
(6)
EMC plate
(attached as standard)
A steel plate used to connect shielded earth wires from inverter's power cables or to
connect earth wires from external devices.
(7)
Braking resistor
Use when rapid deceleration or stop is frequently required or when it is desired to reduce
the deceleration time with large load. This resistor consumes regenerative energy during
power generation braking.
•
Braking resistor - With (re protective thermal relay) built in.
(8)
Surge suppression filter
(400V class only)
Use an insulation-reinforced motor or install the surge voltage restraint filter to prevent
degrading motor insulation caused by surge voltage generation depending on cable length
and wiring method, or use of a 400V class motor driven with an inverter.
