Important User Information

(2) Wiring

Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the output of the inverter.

The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor.

Incorrect terminal wiring could result in the equipment damage. Reversing the polarity (+/-) of the terminals could damage the inverter.

Only authorized personnel familiar with LG inverter should perform wiring and inspections.

Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily injury.

(3) Trial run

Check all parameters prior to operation. Changing parameter values might be required depending on the load.

Always apply permissible range of voltage to the each terminal as indicated in this manual. Otherwise, it could lead to inverter damage.

(4) Operation precautions

When the Auto restart function is selected, stay away from the equipment as a motor will restart suddenly after a fault stop.

The Stop key on the keypad is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately.

If a fault reset is made with the reference signal present, a sudden start will occur. Check that the reference signal is turned off in advance. Otherwise an accident could occur.

Do not modify or alter anything inside the inverter.

Motor might not be protected by electronic thermal function of inverter.

Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.

Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected.

In case of input voltage unbalance, install AC reactor. Power Factor capacitors and generators may become overheated and damaged due to potential high frequency noise transmitted from inverter.

Before operating unit and prior to user programming, reset user parameters to default settings.

Inverter can easily be set to high-speed operations. Verify capability of motor or machinery prior to operating unit.

Stopping torque is not produced when using the DC-Break function. Install separate equipment when stopping torque is needed.

(5) Fault prevention precautions

Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.

(6) Maintenance, inspection and parts replacement

Do not conduct a megger (insulation resistance) test on the control circuit of the inverter.

Refer to Chapter 13 for periodic inspection (parts replacement).

(7) Disposal

Handle the inverter as an industrial waste when disposing of it.

(8) General instructions

Many of the diagrams and drawings in this instruction manual show the inverter without a circuit breaker, a cover or partially open. Never run the inverter like this. Always place the cover with circuit breakers and follow this instruction manual when operating the inverter.
