Thank you for purchasing LS Variable Frequency Drives!
Safety instructions are prepared to use the product safely and correctly by preventing any accident or risk beforehand, so
they should be always kept.
z In this manual, safety instructions are divided into two classes; each has the following meaning.
z Throughout this manual, we use the following two illustrations to make you aware of safety considerations.
z After reading this manual, keep it handy for any user to quickly refer to
z Read this manual carefully to user SV-iE5 Series Inverter’s functions appropriately and safely.
z Do not remove the cover while the power is applied or the unit is in operation.
Or, it may cause electric shock.
z Do not run the inverter with the front cover removed.
Or, it may cause an electric shock due to high voltage terminals or charged capacitor exposure.
z Do not remove the cover except for periodic inspections or wiring, even if the input power is not applied.
Or, it may cause an electric shock due to charged capacitor exposure even if the power is cut off.
z Wiring 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).
Or, it may cause an electric shock (below DC 30V)
z Operate the switches with dry hands.
Or, it may cause an electric shock.
z Do not use the cable when its insulating tube is damaged.
Or, it may cause an electric shock.
z Do not subject the cables to any heavy load stressful to them.
Or, it may cause an electric shock due to damaged cable.

z Install the inverter on a non-flammable surface.
Or, it may cause a fire if being installed on or closely to a flammable material.
z Disconnect the input power if the inverter gets damaged.
Or, it may result in a secondary accident and fire.
z After the input power is applied or removed, the inverter will remain hot for a couple of minutes.
Otherwise, you get bodily injuries such as skin-burn or damage.
z Do not apply power to a damaged inverter or an inverter with parts missing even if the installation is complete.
Or, it may cause an electric shock.
z Do not allow screw, metal chips, water drops, oil or other impurities into the inverter.
Or, it may cause a fire.
(1) Transport and installation
z Carry it correctly according to the specified weight.
z Do not stack the inverter boxes higher than recommended.
z Install according to instruction specified in this manual.
z Do not open the cover during transport.
z Do not place any heavy load on the inverter.
z Check whether the inverter mounting direction is correct.
z Do not drop the inverter, or subject it to impact.
z Follow your national electrical code for grounding(200V).
z As soon as detaching PCB(Printed Circuit Board) for installation or repair, make sure to place it on conductor.
Otherwise, it may cause destruction due to static electricity.
z Use the inverter under the following environmental conditions.
Ambient temperature - 10 ~ 40 (non
℃ -freezing)
Relative humidity 90% RH or less (non-condensing)
Storage temperature - 20 ~ 65 ℃

(2) Wiring
z Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the output of the inverter.
z The connection orientation of the output cables should be in good order of U, V, W.
z Incorrect terminal wiring could result in the equipment damage.
z Reversing the polarity (+/-) of the terminals could damage the inverter.
z The only authorized and skilled person should perform wiring and inspections.
z Always install the inverter before wiring.
(3) Trial run
z Check all parameters during operation. Changing parameter values might be required depending on the load.
z 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
z Note that if the Auto restart function is selected, you must stay away from the equipment as a motor will restart
suddenly after an alarm stop.
z The Stop key on the keypad is activated only when the setting has been made. Prepare an emergency stop switch
separately.
z If any fault is reset with the reference signal present, a sudden start will automatically occur. Check that the
reference signal is turned off in advance. Otherwise an accident could occur.
z Do not modify or alter the inverter without permission.
z Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
z Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may
be affected.
z 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.
z Before operating unit and prior to user programming, reset user parameters to default settings.
z Inverter can easily be set to high-speed operations, Verify capability of motor or machinery prior to operating unit.
z Stopping torque is not produced when using the DC-Break function. Install separate equipment when stopping
torque is needed.
(5) Fault prevention precautions
z 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
z Do not conduct a megger (insulation resistance) test on the control circuit of the inverter.
z Refer to Chapter 13 for periodic inspection (parts replacement).

(7) Disposal
z Dispose of the inverter as treating industrial waste.
(8) General instructions
z 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.
