Application Wiring Apparatus & Option
HYUNDAI INVERTER
1. Field wiring connection must be made in accordance with a UL-listed and CSA-certified
closed-loop terminal connector sized for the wire gauge required.
Connector must be fixed using the crimping tool specified by the connector manufacturer.
2. Properly select the capacity of the circuit breaker to be used.
3. Check power wire size if cable length exceeds 20 m.
4. Use 0.75 mm

Name
Function
Input-side AC reactor for
harmonic suppression/ power
coordination/
power improvement
This is useful when harmonic suppression measures must be taken,
when the main power voltage unbalance rate exceeds 3% and the
main power capacity exceeds 500 kVA, or when a sudden power
voltage variation occurs. It also helps to improve the power factor.
Vibration may increase when driving a general-purpose motor with
an inverter as compared with commercial power operation.
Connecting this reactor between the inverter and the motor allows
reduction of motor pulsation. When the cable between the inverter
and the motor is 10 m or more, inserting the reactor prevents
thermal relay malfunction caused by harmonics resulting from
inverter switching.
A current sensor can be used instead of the thermal relay.
