Refer to "(4) Common applicable tools"
(Note1) The applicable tools indicate for Hyundai standard four-pole squirrel-cage Motor
(Note2) Select applicable tools for breakers examining the capacity of breakers.
(Use Inverter type.)
(Note3) Use earth-leakage breakers (MCCB) for safety.
(Note4) Use 60/75
(Note5) It needs bigger wires for power lines, if the distance exceeds 20m.
(Note6) Use 0.75mm for Alarm output contact.
(Note7) Separate by the sum wiring distance from Inverter to power supply, from inverter
to motor for the sensitive current of leak breaker (MCCB)
Wiring distance
100m and less
300m and less
(Note8) When using CV wire and wiring by rigid metal conduit, leak flows.
(Note9) IV wire is high dielectric constant. So the current increase 8 times.
Therefore, use the sensitive current 8 times as large as that of the left list.
And if the distance of wire is over 100m, use CV wire.

Function
This part is used when the nubalance voltage rate is 3% or more and power
supply is 500KVA or more, and there is a rapid change in the power supply.
It also improves the power factor.
Using the the inverter may cause noise on the peripheral radio through
the power lines. This part reduces noise.
This part reduces common noise generated between the power
supply and ground, as well as normal noise. Put it in the primary
side of inverter.
This part reduces radiation noise emitted from wire at the input
This part control harmonic from inverter.
This part is used for applications that need to increase the brake
torque of the inverter or to frequently turn on and off and to run
high inertia load.
This part reduces radiation noise emitted from wire by setting between
inverter and motor. And it reduces wave fault to radio and TV, it is used for
preventing malfunction of sensor and measuring instruments.
This part reduces noise generated at the output of the inverter.
(It is possible to use for both input and output)
Running motors with the inverter generates vibration greater than that with
commercial power supply. This part installed between the inverter and mo-
tor reduces torque ripple. When the cable length between the inverter and
motor is long (10m or more), a countermeasure for a malfunction of the
thermal relay by harmonic due to switching on inverter is taken by inserting
reactor. There is the way to use current sensor in stead of thermal relay.
