WARNING DISPLAY

WARNING

DANGER

Risk of electric shock.

Before opening the cover, wait at least 5 minutes until DC bus capacitors discharge. Ensure proper earth connection.

Refer to the user's manual before installation and operation.

A warning label is displayed on the terminal cover of the inverter,

as shown in the figure.

Follow these instructions when handling the inverter.

plus

Do not Run/Stop operation by switching on/off electromagnetic contactors (Mc0, Mc1) on the primary or secondary sides of the inverter.

Operate the inverter by Run/Stop commanding [FW/RV].

Inverter

Motor Terminal Surge Voltage Suppression Filter (for the 400V class)

In a system using an inverter with the voltage control PWM system, a voltage surge caused by the cable constants such as the cable length (especially when the distance between the motor and inverter is 10m or more) and cabling method may occur at the motor terminals. A dedicated filter of the 400V class for suppressing this voltage surge is available. Be sure to install a filter in this situation.

Input power disconnection

This inverter is not able to protect input power disconnection. Be careful to connect the wires.

plus

In the cases below involving a general-purpose inverter, a large peak current flows on the power supply side, sometimes destroying the converter module.

The unbalance factor of the power supply is 3% or higher.

The power supply capacity is at least 10 times greater than the inverter capacity(and the power supply capacity, 500kVA or more).

Abrupt power supply changes are expected.

some examples) Several inverters are interconnected with a short bus. An installed leading capacitor opens and closes.

RC Value of the thermal Relay is 1.1 times greater than the motor rated current. Also, RC Value is adjustable to the wiring distance, but contacts us in this case.

Do not connect and disconnect the power supply more than 1/5(number / minute)

There is the danger of inverter damage.

When the EEPROM error E 08 occurs, be sure to confirm the setting values again.

Footnotes for the preceding tables :

1.The protection method conforms to JEM 1030.

2.The applicable motor refers to HYUNDAI standard 3-phase motor (4-pole). To use other motors, care must be taken to prevent the rated motor current(50/60Hz) from exceeding the rated output current of the inverter.

3.The output voltage decreases as the main supply voltage decreases (except for use of the AVR function). In any case, the output voltage cannot exceed the input power supply voltage.

4.To operate the motor beyond 50/60Hz, consult the motor mamanufacturer about the maximum allowable rotation speed.

5.The braking torque via capacitive feedback is the average decelection torque at the shortest deceleration (stopping from 50/60Hz as indicated). It is not continuous regenerative braking torque. And, the average deceleration torque varies with motor loss. This value decreases when operating beyond 50 Hz. If a large regenerative torque is required, the optional regenerative braking resistor should be used.

6.Control method setting A31 to 2 (sensorless vector control) Selected, set carrier frequency setting b11 more than 2.1kHz.

Before proceeding to the wiring section, it's good time to temporarily

cover the inverter's ventilation openings. It will prevent harmful debris such as wire clippings and metal shavings from entering the inverter during installation

CAUTION

The ambient temperature must be in the range of-10 to 40. If the range will be up to 50, you will need to set the carrier frequency to 2kHz or less and derate the output current to 80% or less.
