SAFETY INSTRUCTIONS
Always follow safety instructions to prevent accidents and potential hazards from occurring.
In this manual, safety messages are classified as follows:
WARNING
CAUTION
Throughout this manual we use the following two illustrations to make you aware of safety
considerations:
Identifies potential hazards under certain conditions.
Read the message and follow the instructions carefully.
Identifies shock hazards under certain conditions.
Particular attention should be directed because dangerous voltage may be present.
Keep operating instructions handy for quick reference.
Read this manual carefully to maximize the performance of SV-iG5A series inverter and ensure
its safe use.
WARNING
Do not remove the cover while power is applied or the unit is in operation.
Otherwise, electric shock could occur.
Do 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.
Do 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.
Improper operation may result in slight to medium personal injury
or property damage.
Improper operation may result in serious personal injury or death.

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).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use the cable when its insulating tube is damaged.
Otherwise, you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or
pinching.
Otherwise, you may get an electric shock.
CAUTION
Install the inverter on a non-flammable surface. Do not place flammable
material nearby.
Otherwise, fire could occur.
Disconnect the input power if the inverter gets damaged.
Otherwise, it could result in a secondary accident and fire.
After the input power is applied or removed, the inverter will remain hot for
a couple of minutes.
Otherwise, you may get bodily injuries such as skin-burn or damage.
Do 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.
Do 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.
Follow your national electrical code for grounding. Recommended Ground impedance for
200 V Class is below 100 ohm and for 400V class below 10 ohm.
iG5A series contains ESD (Electrostatic Discharge) sensitive parts. Take protective
measures against ESD before touching the pcb for inspection or installation.
Use the inverter under the following environmental conditions:
Environment
Surrounding temperature
- 10 ~ 50 ℃(non-freezing)
Relative humidity
90% RH or less (non-condensing)
Storage temperature
- 20 ~ 65 ℃
Location
Protected from corrosive gas, combustible gas,
oil mist or dust
Altitude, Vibration
Max. 1,000m above sea level, Max. 5.9m/sec2
(0.6G) or less
Atmospheric 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 LS 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.
In case of input voltage unbalance, installAC 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. Amicro 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 12 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.

CHAPTER 2 - INSTALLATION & WIRING
2.1 Installation precautions
CAUTION
Handle the inverter with care to prevent damage to the plastic components. Do not hold the
inverter by the front cover. It may fall off.
Install the inverter in a place where it is immune to vibration (5.9 m/s2 or less).
Install in a location where temperature is within the permissible range (-10~50C).
<Ambient Temp Checking Location>
The inverter will be very hot during operation. Install it on a non-combustible surface.
Mount the inverter on a flat, vertical and level surface. Inverter orientation must be vertical
(top up) for proper heat dissipation. Also leave sufficient clearances around the inverter.
Protect from moisture and direct sunlight.
Do not install the inverter in any environment where it is exposed to waterdrops, oil mist,
dust, etc. Install the inverter in a clean place or inside a “totally enclosed”panel any
suspended matter is not entered.

When two or more inverters are installed or a cooling fan is mounted in a panel, the inverters
and fan must be installed in proper positions with extreme care to keep the ambient
temperature below the permissible range.
Installed the inverter using screws or bolts to insure the inverter is firmly fastened.
< For installing multiple inverters in a panel>
CAUTION
Take caution on proper heat ventilation when installing inverters and fans in a panel.
