Otherwise, you may get an electric shock due to high voltage terminals or charged capacitor
exposure.
 Do not remove the cover except for perio ic inspections or wiring, even if
the input power is not applie .
Otherwise, you may access the charged circuits and get an electric shock.
 Wiring an perio ic inspections shoul be performe at least 10 minutes
after isconnecting the input power an after checking the DC link voltage
is ischarge with a meter (below DC 30V).
Otherwise, you may get an electric shock.
 Operate the switches with ry han s.
Otherwise, you may get an electric shock.
 Do not use the cable when its insulating tube is amage .
Otherwise, you may get an electric shock.
 Do not subject the cables to scratches, excessive stress, heavy loa s or
pinching.

(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 ca les 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 efore wiring. Otherwise, you may get an electric shock or have odily injury.
(3) Trial run
 Check all parameters prior to operation. Changing parameter values might e required depending on the load.
 Always apply permissi le 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
a fault stop.
 The Stop key on the keypad is valid only when the appropriate function setting has een made. Prepare an
emergency stop switch separately.
 If a fault 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 e protected y 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 near y electronic equipment
may e affected.
 In case of input voltage un alance, install AC reactor. Power Factor capacitors and generators may ecome
overheated and damaged due to potential high frequency noise transmitted from inverter.
 Before operating unit and prior to user programming, reset user parameters to default settings.
 Inverter can easily e set to high-speed operations. Verify capa ility 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 ackup such as an emergency rake 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 13 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 reaker, a
cover or partially open. Never run the inverter like this. Always place the cover with circuit reakers and follow
this instruction manual when operating the inverter.

2.1 Installation precautions
CAUTION
 Handle the inverter with care to prevent damage to the plastic components. Do not hold the inverter y the front
cover. It may fall off.
 Install the inverter in a place where it is immune to vi ration (5.9 m/s
2
or less). The inverter is under great influence
of am ient temperature.
 Install in a location where temperature is within the permissi le range (-10~50°C) . Maximum Surroun ing Air
Temperature is 50°C. Mo els SV004iC5-1, SV004iC5-1F, SV008iC5-1, an SV008iC5-1F can be use in
Ambient 40°C. (UL 508C)
`
<Ambient Temp Chec ing Location>
 The inverter will e very hot during operation. Install it on a non-com usti le surface.
 Mount the inverter on a flat, vertical and level surface. Inverter orientation must e 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 which does not accept any suspended matter.

 When two or more inverters are installed or a ventilation fan is mounted in inverter panel, the inverters and ventilation
fan must e installed in proper positions with extreme care taken to keep the am ient temperature of the inverters
elow the permissi le value. If they are installed in improper positions, the am ient temperature of the inverters will rise
and ventilation effect will e reduced.
 Install the inverter using screws or olts to insure the inverter is firmly fastened.

CAUTION
 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. If tester
is available, check the voltage between P1 and N terminals. Wiring should be
performed after verifying that input voltage in inverter DC circuitry is all
exhausted.
 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.
 Never short P1 or P and N 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.
