any problems, please contact your distributor.
1.2 Storage
The AC motor drive should be kept in the shipping carton or crate before installation. In order to
retain the warranty coverage, the AC motor drive should be stored properly when it is not to be used
for an extended period of time. Storage conditions are:
Store in a clean and dry location free from direct sunlight or corrosive fumes.
Store within an ambient temperature range of -20°C to +60°C.
Store within a relative humidity range of 0% to 90% and non-condensing environment.
Store within an air pressure range of 86kPa to 106kPa.
CAUTION!
1. DO NOT store in an area with rapid changes in temperature. It may cause condensation and
frost.
2. DO NOT place on the ground directly. It should be stored properly. Moreover, if the surrounding
environment is humid, you should put exsiccator in the package.
3. If the AC motor drive is stored for more than 3 months, the temperature should not be higher
than 30 °C. Storage longer than one year is not recommended, it could result in the degradation
of the electrolytic capacitors.
4. When the AC motor drive is not used for a long time after installation on building sites or places
with humidity and dust, it’s best to move the AC motor drive to an environment as stated above.

1. Mount the AC motor drive vertically on a flat vertical surface by using bolts or screws. Other
directions are not allowed.
2. The AC motor drive will generate heat during operation. Allow sufficient space around the unit
for heat dissipation.
3. The heat sink temperature may rise to 90°C when running. The material on which the AC motor
drive is mounted must be noncombustible and be able to withstand this high temperature.
4. When the AC motor drive is installed in a confined space (e.g. cabinet), the surrounding
temperature must be within 10 ~ 40°C with good ventilation. DO NOT install the AC motor drive
in a space with bad ventilation.
5. When installing multiple AC motor drives in the same cabinet, they should be adjacent in a row
with enough space. When installing one AC motor drive below another one, use a metal
separation barrier between the AC motor drives to prevent mutual heating. Refer to figure below
for details.
6. Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the
heatsink.

2.4 Wiring
After removing the front cover, check if the power and control terminals are clear of debris. Be sure
to observe the following precautions when wiring.
2.4.1 Basic Wiring
Make sure that power is only applied to the L1, L2 terminals. Failure to comply may
result in damage to the equipment. The voltage and current should lie within the range
as indicated on the nameplate.
Check the following items after completing the wiring:
1. Are all connections correct?
2. No loose wires?
3. No short-circuits between terminals or to ground?
A charge may still remain in the DC bus capacitors with hazardous voltages even if the
power has been turned off. To prevent personal injury, please ensure that the power is
turned off and wait ten minutes for the capacitors to discharge to safe voltage levels
before opening theAC motor drive.
DANGER!
1. All the units must be grounded directly to a common ground terminal to prevent electric shock,
fire and interference.
2. Only qualified personnel familiar with AC motor drives are allowed to perform installation, wiring
and commissioning.
3. Make sure that the power is off before doing any wiring to prevent electric shocks.
Basic Wiring Diagrams
Users must connect wires according to the circuit diagrams on the following pages. Do not plug a
modem or telephone line to the RS-485 communication port or permanent damage may result. The
pins 1 & 2 are the power supply for the optional copy keypad PU06 only and should not be used for
RS-485 communication.

Mains power terminals
It must have a no-fuse breaker between the AC input power and main circuit terminals
(L1, L2).
It is recommended to add a magnetic contactor (MC) in the power input wiring to cut off
power quickly and reduce malfunction when activating the protection function of AC
motor drives. Both ends of the MC should have an R-C surge absorber.
Ground resistance should be less than 100Ω.
The AC motor drive, welding machine and large horsepower motor should ground
separately.
Make sure the power voltage and max. supply current.
Connect a brake resistor in applications with frequent deceleration ramps, short
deceleration time, too low braking torque or requiring increased braking torque.
Do not connect any output terminal (U, V, W) to the AC motor drive power.
Please tighten the screws of the main circuit terminals to prevent a spark due to vibration.
The wiring of main circuit and control circuit should be separated to prevent erroneous
actions. If necessary let them cross only at 90º angle.
Please use the shield wire for the control wiring and do not expose the peeled-off net in
front of the terminal.
Please use the shield wire or tube for the power wiring and ground the two ends of the
shield wire or tube.
If the AC motor drive is installed in the occasion where is sensitive to the interference,
please add an RFI filter as close as the AC motor drive. With the lower of the PWM
carrier frequency, it will have the less interference.

Chapter 2 Installation and Wiring|VFD-L-I Series
2-8 Revision July 2009, SW V1.1
When using a GFCI (Ground Fault Circuit Interrupter), select a current sensor with
sensitivity of 200mA, and not less than 0.1-second detection time to avoid nuisance
tripping.
If the insulation of the control wire is damaged due to some reasons, it may result in the
circuit damage or personal injury.
The AC motor drive, motor and wiring may cause noise interference. Please notice the
surrounding sensors and equipment to prevent erroneous actions.
Main circuit terminals (L1, L2)
Please connect these main circuit terminals (L1, L2) to the AC power via a no-fuse
breaker or electricity leakage breaker for circuit protection. It is unnecessary to consider
phase-sequence.
It is recommended to add a magnetic contactor (MC) in the power input wiring to cut off
power quickly and reduce malfunction when activating the protection function of AC
motor drives. Both ends of the MC should have an R-C surge absorber.
Control circuit terminals (U, V, W)
When the AC drive output terminals U, V, and W are connected to the motor terminals
U/T1, V/T2, and W/T3, respectively, the motor will rotate counterclockwise (as viewed on
the shaft end of the motor) when a forward operation command is received. To
permanently reverse the direction of motor rotation, switch over any of the two motor
leads.
Forward
running
DO NOT connect phase-compensation capacitors or surge absorbers at the output
terminals of AC motor drives.
Use a well-insulated motor, suitable for inverter operation.

Chapter 2 Installation and Wiring|VFD-L-I Series
Revision July 2009, SW V1.1 2-9
Make sure that the leads are connected correctly and the AC drive is properly grounded.
Use ground leads that comply with local regulations and keep them as short as possible
to prevent electric shock or fire.
Multiple VFD-L-I units can be installed in one location. All the units should be grounded
directly to a common ground terminal, as shown in the figure below. Ensure there are
no ground loops.

Chapter 3 Start Up
3.1 Preparations before Start-up
Carefully check the following items before proceeding.
Make sure that the wiring is correct. In particular, check that the output terminals U, V, W
are NOT connected to power and that the drive is well grounded.
Verify that there are no short-circuits between terminals and from terminals to ground or
mains power.
Check for loose terminals, connectors (PG card) or screws.
Verify that no other equipment is connected to the AC motor.
Make sure that all switches are OFF before applying power to ensure that the AC motor
drive doesn’t start running and there is no abnormal operation after applying power.
Make sure that the front cover is correctly installed before applying power.
Do NOT operate the AC motor drive with humid hands.
3.2 Operation Method
Please choose a suitable method depending on application and operation rule. The operation is
usually done as shown in the following table.
