WARNING
nDo not remove the cover while power is applied or the unit is in
operation.
Otherwise, electric shock could occur.
nDo not run the inverter with the front cover removed.
Otherwise, you may get an electric shock due to high voltage terminals or charged
capacitor exposure.
nDo not remove the cover except for periodic inspections or wiring,
even if the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
nWiring and periodic inspections should be performed at least 10
minutes after disconnecting the input power and after checking the
DC link voltage is discharged with a meter (below DC 30V).
Otherwise, you may get an electric shock.
nOperate the switches with dry hands.
Otherwise, you may get an electric shock.
nDo not use the cable when its insulating tube is damaged.
Otherwise, you may get an electric shock.
nDo not subject the cables to scratches, excessive stress, heavy
loads or pinching.
Otherwise, you may get an electric shock.

III
CAUTION
nInstall the inverter on a non-flammable surface. Do not place
flammable material nearby.
Otherwise, fire could occur.
nDisconnect the input power if the inverter gets damaged.
Otherwise, it could result in a secondary accident and fire.
nDo not touch the inverter while the input power is applied or after
removed. It will remain hot for a couple of minutes.
Otherwise, you may get bodily injuries such as skin-burn or damage.
nDo not apply power to a damaged inverter or to an inverter with
parts missing even if the installation is complete.
Otherwise, electric shock could occur.
nDo not allow lint, paper, wood chips, dust, metallic chips or other
foreign matter into the drive.
Otherwise, fire or accident could occur.
OPERATING PRECAUTIONS
(1) Handling and installation
¨Handle according to the weight of the product.
¨Do not stack the inverter boxes higher than the number recommended.
¨Install according to instructions specified in this manual.
¨Do not open the cover during delivery.
¨Do not place heavy items on the inverter.
¨Check the inverter mounting orientation is correct.
¨Do not drop the inverter, or subject it to impact.
¨Use the ground impedance of 100ohm or less for 200 VClass and 10ohm or less for
400V class.
¨Take protective measures against ESD (Electrostatic Discharge) before touching the
pcb for inspection or installation.
¨Use the inverter under the following environmental conditions:

pressure 70 ~ 106 kPa
(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 during 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 an alarm 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 an alarm 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.

V
¨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.
¨Use an insulation-rectified motor or take measures to suppress the micro surge voltage
when driving 400V class motor with inverter. A micro surge voltage attributable to
wiring constant is generated at motor terminals, and may deteriorate insulation and
damage motor.
¨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 8for 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.

2. OVERLOAD PROTECTION
IOLT: IOLT(inverter Overload Trip) protection is activated at 150% of the inverter rated current for
1 minute and greater.
OLT : Inverter shuts off its output when inverter output current exceeds its overload trip level for
overload trip time. OLT is selected when FU1-56 is set to “Yes”and activated at 120% of FU1-57
[Motor rated current] for 60 sec set in FU1-58.
3. OVER SPEED PROTECTION
“Not Provided With Overspeed Protection”.
4.Risk of Electric Shock
More than one disconnect switch may be required to de-energize the equipment before servicing.
