Standard Accessories
Notes: 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 20 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.
Notes: 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.
FunctionName
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.
Electrical noise interference may occur on nearby equipment such
as a radio receiver. This magnetic choke filter helps reduce radiated
noise.
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).
This capacitive filter reduces radiated noise from the main power
wires in the inverter input side.
The inductor or choke filter suppresses harmonics generated by the inverter.
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.
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.
Electrical noise interference may occur on nearby equipment such
as a radio receiver. This magnetic choke filter helps reduce radiated
noise.
Install it on the output side to reduce leakage current contributed by
higher harmonics. Contact our company for details.
