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, 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 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.

CAUTION

 Apply the rated torque to terminal screws. Loosen screws can cause of short circuit and

malfunction. Tightening the screw too much can damage the terminals and cause short
circuit and malfunction.

 Use copper wires only with 600V, 75℃ ratings for wiring.
 Make sure the input power is off before wiring.

 When power supply is switched off following operation, wait at least 10 minutes after LED

keypad display is off before you start working on it.

 Applying input power supply to the output terminals U, V and W causes internal inverter

damage.

 Use ring terminals with insulated caps when wiring the input power and motor wiring.
 Do not leave wire fragments inside the inverter. Wire fragments can cause faults,

breakdowns and malfunctions.

 When more than one motor is connected to one inverter, total wire length should be less

than 200m (656ft). Do not use a 3-wire cable for long distances. Due to increased leakage
capacitance between wires, over-current protective feature may operate or equipment
connected to the output side may malfunction. In case of long wire length, it should be
required to lower carrier frequency or use Micro Surge Filter.

Length between Inverter and Motor

Up to 50m

Up to 100m

More than 100m

Allowable Carrier Frequency

Less than 15kHz

Less than 5kHz

Less than 2.5kHz

(For products of less than 3.7kW, the wire length should be less than 100m(328ft)).

 Never short B1 and B2 terminals. Shorting terminals may cause internal inverter damage.
 Do not install a power factor capacitor, surge suppressor or RFI filters in the output side of

the inverter. Doing so may damage these components.

[WARNING]
Power supply must be connected to the R, S, and T Terminals.

Connecting it to the U, V, W terminals causes internal damages to the inverter. Arranging the
phase sequence is not necessary.

Motor should be connected to the U, V, and W Terminals.

If the forward command (FX) is on, the motor should rotate counter clockwise when viewed from
the load side of the motor. If the motor rotates in the reverse, switch the U and V terminals.

CHAPTER 3 - BASIC CONFIGURATION

3.1 Connection of peripheral devices to the inverter

The following devices are required to operate the inverter. Proper peripheral devices must be
selected and correct connections made to ensure proper operation. An incorrectly applied or
installed inverter can result in system malfunction or reduction in product life as well as component
damage. You must read and understand this manual thoroughly before proceeding.

AC Source Supply

Use the power supply within the
permissible range of inverter input power
rating (Refer to Page 13-1).

MCCB or Earth
leakage circuit
breaker (ELB)

Select circuit breakers with care. A large
inrush current may flow in the inverter at
power on.

Magnetic Contactor

Install it if necessary. When installed, do
not use it for the purpose of starting or
stopping. Otherwise, it could lead to
reduction in product life.

AC and DC
Reactors

notice1

The AC reactors must be used when the
power factor is to be improved or the
inverter is installed near a large power
supply system (more than 10 times of
inverter capacity and wiring distance
within 10m).

Installation and
wiring

To operate the inverter with high
performance for a long time, install the
inverter in a proper place in the correct
direction and with proper clearances.
Incorrect terminal wiring could result in
the equipment damage.

To motor

Do not connect a power factor capacitor,
surge suppressor or radio noise filter to
the output side of the inverter.

Notice1) Terminal block for DC reactor is composed in the more
than 11kw capacity
