Safety Information
SAFETY INSTRUCTIONS
Always follow safety 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 resultin 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 bedirected because dangerous voltage may be

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.

iii
Safety Information
Do not remove the cover whilepower 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 getan electric

shockdue to high voltage terminalsor 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.
Wiring and periodic inspections should be performed at least 10 minutes afterdisconnecting

the inputpower 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 mayget 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 orpinching.

Otherwise, youmay get an electric shock.
Install the inverteron a non-flammable surface. Do not place flammablematerial nearby.

Otherwise, fire could occur.
Disconnect the inputpower if the inverter getsdamaged. Otherwise, it could result in a

secondary accident and fire.
After the input power is appliedor removed, the inverter will remain hot for a couple of

minutes. Otherwise, you maygetbodilyinjuries 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 allowlint, paper, wood chips, dust,metallic chips or other foreign 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 instructionsspecified in this manual.Do not open the cover during delivery.Do not place heavy items on the inverter.Check the inverter mounting orientationis 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.
iG5H series contains ESD (Electrostatic Discharge) sensitive parts. Take protectivemeasuresagainst 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) orless
Atmospheric pressure
70 - 106 kPa
(2) Wiring
Do not connect a power factor correction capacitor, surge suppressor, or RFI filter tothe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 theterminals could damage the inverter.Only authorized personnel familiar with LS inverter should perform wiring andinspections.
Always install the inverter before wiring. Otherwise, youmay get an electricshock orhave bodily injury.
(3) Trial run
Check all parameters during operation. Changing parameter values might berequireddepending on the load.
Always apply permissible range of voltage to the each terminal as indicated in thismanual. Otherwise, it could leadto inverter damage.

v
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 modify or 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, installACreactor. 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 suppressthe 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 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 likethis.Alwaysplace
the cover with circuit breakers and follow this instruction manual when operating the
inverter.
