(3) Applicable Tools
Note1 : The applicable equipment is for HYUNDAI standard four pole
squirrel cage motor.
Note2 : Be sure to consider the capacity of the circuit breaker to be used.
Note3 : Be sure to use larger wire for power lines if the distance exceeds 20m.
Note4 : Be sure to use an grounding wire same size of power line or similar.
Note5 : Use 0.75㎟for AL relay.
Wiring distance
100m and less
300m and less
Table2-4 Sensitive current according to wiring distance
Note6 : When using CV line and wiring by rigid metal conduit, leak flows.
Note7 : IV line 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 line.

This part is used when the unbalance voltage rate is 3% or more and
power supply is 500 kVA or more, and there is a rapid change in the
power supply. It also improves the power factor.
This part reduces common noise generated between the power
supply and the ground, as well as normal noise. Put it in the primary
side of inverter.
Using the inverter may cause noise on the peripheral radio through
the power lines.
This part reduces noise.
This part reduces radiation noise emitted from wire at the input.
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 motor 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.
