Do not open the inverter covers while it is energized or operating.
Doing so may cause the inverter to malfunction or result in electric shock.
Do not allow objects, such as metal filings or other debris inside the inverter.
Doing so may cause the inverter to malfunction or result in a fire.
Ensure that cables are correctly specified for the inverter's rated voltage, cable entry,
and terminal arrangement. Ensure that all wiring connections are installed correctly.
Incorrect cable specifications and connections may cause the inverter to malfunction or result
in a fire.
Apply the correctly rated torque when tightening terminal screws.
Loose screws or over tightened screws may result in an electric shock or a fire.
Do not install the inverter near flammable objects.
Doing so may cause a fire.
Ensure that the inverter location or installation method is not affected by vibration.
Vibration may affect the inverter's operation and result in an electric shock or fire.
Ensure that the inverter is not serviced or repaired by unauthorized persons.
Unauthorized work may result in an electric shock or a fire and void the warranty.
Ensure the inverter load does not exceed the product's rated load and that the inverter is
installed in accordance with the environmental conditions specified in the User's
Manual.
Exceeding the rated load or incorrectly installing the inverter may cause the inverter to
malfunction, overheat, or result in an electric shock or a fire.

Questions and answers
How to correct error on soft starter after the output has failed to start the motorr
To correct an error on the LS Starvert-iG5A soft starter after the output has failed to start the motor, follow these steps:
1. Check for trip causes: The inverter may have tripped. Common causes include emergency stop (BX), low voltage, short circuits, fuse open, external trip, inverter/motor overheat, encoder error, overload, or AC fan/power faults.
2. Reset the inverter: If the automatic restart count has reached the limit set in FUN_60, the inverter will not restart automatically. In this case, press the reset key on the loader to clear the trip and reinitialize the restart count.
3. Inspect motor wiring: Ensure motor wiring is correct, especially for dual-rated motors (220V/380V). Incorrect wiring can prevent the motor from starting or cause damage.
4. Check motor parameters: Verify that PAR_07 (motor rating selection) matches the motor in use. Also, confirm other motor parameters are set correctly, especially if using a motor from a different manufacturer.
5. Ensure power and connections: Confirm that the inverter power is turned on and the keypad is properly connected.
If these steps do not resolve the issue, further inspection or factory service may be required.
