Note 1: Field wiring connection must be made by a UL and c-UL listed closed-loop terminal connector sized for the wire gauge involved. Connector must be fixed using the crimping tool specified by the connector manufacture.

Note 2: Be sure to use large wire gauges for power wiring if the distance exceeds 20m (66ft).

Name

Function

 

 

This is useful in suppressing harmonics induced on the power supply

Input side AC reactor

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.

 

EMI filter

Reduces the conducted noise on the power supply wiring generated by

the inverter. Connect to the inverter input side.

 

 

Radio noise filter

Electrical noise interference may occur on nearby equipment such as a

radio receiver. This magnetic choke filter helps reduce radiated noise

 

(can also be used on output).

 

Radio noise filter

This capacitor filter reduces radiated noise from the main power wires in

(Capacitor filter)

the inverter input side.

DC link choke

Suppresses harmonics generated by the inverter.

 

Braking resistor

This is useful for increasing the inverter's control torque for high

 

duty-cycle (on-off) applications, and improving the decelerating capability.

Braking unit

 

 

 

Output side noise filter

Reduces radiated noise from wiring in the inverter output side.

 

Radio noise filter

Electrical noise interference may occur on nearby equipment such as a

radio receiver. This magnetic choke filter helps reduce radiated noise

 

(can also be used on input).

 

 

This reactor reduces the vibration in the motor caused by the inver-ter's

AC reactor

switching waveforms, by smoothing the waveforms to approxi-mate

commercial power quality. It is also useful when wiring from the inverter

 

to the motor is more than 10m in length, to reduce harmonics.

LCR filter

Sine wave shaping filter for the output side.

 

 

Note: An EMI filter is required for European EMC directive and C-Tick, but the others are not for this purpose.
