Name Function
Input AC reactor for
harmonic
suppression/power
smoothing/powerfactor
improvement
This is useful in suppressing harmonics induced on the power
supply lines, 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.
Radio noise filter
Zero-phase reactor
Electrical noise interference may occur on nearby equipment
such as a radio receiver. This magnetic choke filter helps
reduce radiated noise.
Input noise filter This filter reduces the conducted noise in the power supply
wiring between the inverter and the power distribution system.
Connect it to the inverter primary (input side).
Regenerative braking
resistor
HF-320 only
The regenerative braking resistor is useful for increasing the
inverter's control torque for high duty-cycle (on-off) applications,
and improving the decelerating capacity.
Output noise filter This filter reduces radiated noise emitted on the inverter output
cable that may interfere with radio or television reception and
test equipment and sensor operation.
Radio noise filter
Zero-phase reactor
Electrical noise interference may occur on nearby equipment
such as a radio receiver. This magnetic choke filter helps
reduce radiated noise.
Input radio noise filter
(XY filter)
This capacitive filter reduces radiated noise from the main
power wires in the inverter input side.
DC reactor The inductor or choke filter suppresses harmonics generated by
the inverter.
Output AC reactor Install it on the output side to reduce leakage current
contributed by higher harmonics. Contact our company for
details.

Note: 1. The shown accessories are for use with SUMITOMO 3-phase, 4-pole motors.
2. Select the circuit breaker based on required capacity.
3. Use thicker cables when wiring distance exceeds 30 m.
*The alarm output point should be 0.75 mm

.
When using an earth leakage breaker (ELB), select the breaker's trip
current from the table
below based on the total wire distance (R) by summing the distance from the breaker to the
inverter and the inverter to the motor.

Note: 1. When CV wiring is used in metal conduit, the
leakage current is approximately 30mA/km.
2. Leakage current will increase eightfold with IV type
cable due to higher dielectric constant. In this case,
use ELB with the next higher trip rating.
