Safety Information
SAFETY INSTRUCTIONS
Always followsafety instructions to prevent accidents and potential hazards fromoccurring.
In this manual, safety messages are classified as follows:
Improper operation mayresult in serious personal injury or death.
Improper operation may result in slight to medium personal injury or property damage.
Throughout this manual we use the following two illustrations to make you aware ofsafetyconsiderations:
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 maybe

present.
Keep operating instructions handy for quick reference.
Read this manual carefully to maximize the performance of SV-iG5H series inverter andensure its safe use.

Safety Information
Do not remove the cover whilepower is applied or the unit is in operation. Otherwise,

electric shock could occur.
Do not run theinverter with the front cover removed. Otherwise, you may get an electric

shock due to high voltage terminalsor chargedcapacitorexposure.
Do not remove the coverexcept for periodic inspections or wiring, even if the inputpower is

not applied. Otherwise,you may access the charged circuits and get an electric shock.
Wiring and periodicinspections should be performed at least 10 minutes after disconnecting

the input power and afterchecking the DC link voltage is discharged with ameter (below DC
30V). Otherwise, you may getan 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,heavyloads or pinching.

Otherwise, youmay get an electric shock.
Install the inverter on a non-flammablesurface. Do not place flammable material nearby.

Otherwise,fire could occur.
Disconnect the inputpower if the inverter gets damaged. Otherwise, it could result in a

secondary accidentand fire.
After the input power is applied or removed, the inverter will remain hot for a couple of

minutes. Otherwise, you mayget bodilyinjuries such as skin-burn or damage.
Do not applypower to a damaged inverter or to an inverter with partsmissing even if the

installation is complete. Otherwise,electric shock could occur.
Do not allow lint, paper, wood chips, dust,metallic chips or otherforeign matter into the

drive. Otherwise,fire or accident could occur.

Safety Information
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 electricalcode for grounding. RecommendedGround impedancefor 200 V Class is below 100 ohm and for 400V class below 10 ohm.
iG5H 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, surgesuppressor, 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 personnelfamiliar with LSinverter 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 applypermissible range of voltage to the each terminal as indicated in thismanual. Otherwise, it could lead to inverter damage.

Safety Information
(4) Operation precautions
When theAuto 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 modifyor alter anything insidethe 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.
Usean insulation-rectified motor or take measures to suppressthemicro surge voltagewhen driving 400Vclass motor with inverter.Amicrosurge voltage attributable to wiring
constant is generated at motor terminals, andmaydeteriorate insulation and damage
motor.
Before operating unit and prior to user programming, reset user parameters to default
settings.
Inverter can easily be set tohigh-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 12.4.2 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.Alwaysplace
the cover with circuit breakers and follow this instruction manual when operating the
inverter.

2 Installation & Wiring
2.1 Installation precautions
Handle the inverterwith care to prevent damage to the plastic components. Do not hold

the inverter by the front cover. It may fall off.
Install the inverterin a place whereit is immune to vibration (5.9 m/s2or less).

Install in a location where temperature is within the permissible range (-10-50 oC).

<AmbientTemp Checking Location>
The inverter will be veryhot during operation. Install it on a non-combustiblesurface.

Mount theinverter on a flat, vertical and level surface.Inverter orientation must be vertical

(top up) for proper heatdissipation.Also leave sufficient clearances around the inverter.
Protect from moisture and direct sunlight.

Installation & Wiring
Installation
Do notinstall the inverter in anyenvironmentwhere itis exposed to waterdrops, oilmist,

dust, etc. Install the inverter in a clean place or inside a “totallyenclosed”panel any
suspended matter is not entered.
When two ormore inverters are installed or a cooling fanis mounted in a panel, the

inverters and fan mustbe 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 theinverter is firmly fastened.

< For installing multiple inverters in a panel>
Take caution on proper heat ventilation when installing inverters and fansin a panel.
