Failure to heed the information indicated by this symbol may lead to
dangerous conditions, possibly resulting in minor or light bodily injuries
and/or substantial property damage.
Failure to heed the information contained under the CAUTION title can also result in serious consequences.
These safety precautions are of utmost importance and must be observed at all times.
Application
• FRENIC-Lift is equipment designed to drive induction motors and synchronous motors for exclusively
controlling elevating machinery. Do not use it for single-phase motors or for other purposes.
Fire or accident could occur.
• FRENIC-Lift may not be used for a life-support system or other purposes directly related to the human
safety.
• Though FRENIC-Lift is manufactured under strict quality control, install safety devices for applications
where serious accidents or material losses are foreseen in relation to the failure of it.
An accident could occur.

ii
Installation
• Install the inverter on a nonflammable material such as metal.
Otherwise fire could occur.
• Do not place flammable matter nearby.
Doing so could cause fire.
• Using an optional DC reactor makes human body easily touch any live parts of inverters. In this case,
take countermeasures such as installing the inverter in a place that easily protects human body from
electric shock.
Otherwise, electric shock or injuries could occur.
• Do not touch the printed circuit boards in the product directly. Electronic devices on those boards are
easily affected by static electricity.
When touching those boards, put on a grounding wrist band and perform the job on a static mat.
Static electricity charged in your body may damage the product.
• Do not support the inverter by its terminal block cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter or from accumulating on the heat sink.
Otherwise, a fire or an accident might result.
• Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.
• Do not get on a shipping box.
• Do not stack shipping boxes higher than the indicated information printed on those boxes.
Doing so could cause injuries.
Wiring
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker
(MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)
(with overcurrent protection) in the path of power lines. Use the devices within the recommended cur-
rent range.
• Use wires in the specified size.
Otherwise, fire could occur.
• Do not use one multicore cable in order to connect several inverters with motors.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause fire.
• Install inverters in compliance with the local regulation.
Otherwise, electric shock or fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter body.
Otherwise, electric shock or injuries could occur.

iii
• Ensure that the number of input phases and the rated voltage of the product match the number of
phases and the voltage of the AC power supply to which the product is to be connected.
Otherwise fire or an accident could occur.
• Do not connect the power source wires to output terminals (U, V, and W).
Doing so could cause fire or an accident.
• Generally, control signal wires are not enforced-insulated. If they accidentally touch any live power
lines, their insulation coat may break for any reasons. In such a case, an extremely high voltage may be
applied to the signal lines. Make a complete remedy to protect the signal line from contacting any live
high voltage lines.
Otherwise, an accident or electric shock could occur.
• Wire the three-phase motor to terminals U, V, and W of the inverter, aligning phases each other.
Otherwise injuries could occur.
• The inverter, motor and wiring generate electric noise. Take care of malfunction of the nearby sensors
and devices. To prevent the motor from malfunctioning, implement noise control measures.
Otherwise an accident could occur.
Operation
• Be sure to install the terminal block cover and the front cover before turning the power ON. Do not
remove the covers while power is applied.
Otherwise electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the retry function has been selected, the inverter may automatically restart and drive the motor de-
pending on the cause of tripping.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• If the stall prevention function (current limiter), automatic deceleration, and overload prevention control
have been selected, the inverter may operate at an acceleration/deceleration time or frequency dif-
ferent from the commanded ones. Design the machine so that safety is ensured even in such cases.
Otherwise an accident could occur.
• If an alarm reset is made with the Run command signal turned ON, a sudden start will occur. Ensure that
the Run command signal is turned OFF in advance.
Otherwise an accident could occur.
• If you set the function codes wrongly or without completely understanding this instruction manual and
the FRENIC-Lift Reference Manual (INR-SI47-1068-E), the motor may rotate with a torque or at a
speed not permitted for the machine.
• In the tuning process of the inverter, no motor torque control for braking of the machinery takes effect.
Tune the inverter for the motor after disconnecting it from the machinery, or after mechanically brakes
the machinery. Anyway, do it after suppressing any dangerous factors.
An accident or injuries could occur.
• Never touch the inverter terminals while the power is applied to the inverter even if the inverter stops.
• Never touch the printed circuit boards in the product while the power is applied to the inverter. High
voltage is applied to those boards.
Doing so could cause electric shock.

iv
• Do not turn the main circuit power (circuit breaker) ON or OFF in order to start or stop inverter operation.
Doing so could cause failure.
• Do not touch the heat sink because they become very hot.
Doing so could cause burns.
• Setting the inverter to high speeds is easy. Before changing the frequency (speed) setting, check the
specifications of the motor and machinery.
• The brake function of the inverter does not provide mechanical holding means.
Injuries could occur.
Setting control switches
• Before setting up any internal control switches, turn OFF the power, and wait for more than five minutes.
Further, check that the LED monitor is unlit, and make sure, using a multimeter or a similar instrument,
that the DC link bus voltage between the terminals P (+) and N (-) has dropped below a safe voltage
(+25 VDC).
Otherwise electric shock could occur.
Maintenance and inspection, and parts replacement
• Turn the power OFF and wait for more than five minutes, before starting inspection. Further, check that
the LED monitor is unlit, and check the DC link bus voltage between the P (+) and N (-) terminals to be
lower than 25 VDC.
Otherwise, electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic matter before starting work.
• Use insulated tools.
Otherwise, electric shock or injuries could occur.
Disposal
• Handle the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.
Others
• Never attempt to modify the inverter.
Doing so could cause electric shock or injuries.
GENERAL PRECAUTIONS
Drawings in this manual may be illustrated without covers or safety shields for explanation of detail parts.
Restore the covers and shields in the original state and observe the description in the manual before
starting operation.

Precautions for use
In running
general-
purpose
motors
Driving a 400V
general-purpose
motor
When driving a 400V general-purpose motor with an inverter using ex-
tremely long wires, damage to the insulation of the motor may occur. Apply
the inverter after consulting the motor maker.
Torque characte-
ristics and tem-
perature rise
When the inverter is used to run a general-purpose motor, the temperature
of the motor becomes higher than when it is operated using a commercial
power supply. In the low-speed range, the cooling effect will be weakened,
so decrease the output torque of the motor.
Vibration
When an inverter-driven motor is mounted to a machine, resonance may
be caused by the natural frequencies of the machine system.
Note that operation of a 2-pole motor at 60 Hz or higher may cause ab-
normal vibration.
* The use of a rubber coupling or vibration dampening rubber is recom-
mended.
* Run your machinery including FRENIC-Lift inverter so as to skip its re-
sonance frequency zone/s.
Noise
When an inverter is used with a general-purpose motor, the motor noise
level is higher than that with a commercial power supply. To reduce noise,
raise carrier frequency of the inverter. Operation at 60 Hz or higher can
also result in higher noise level.
In running
special mo-
tors
Brake motors
For motors equipped with parallel-connected brakes, their braking power
must be supplied from the primary circuit. If the brake power is connected
to the inverter's output circuit by mistake, the brake will not work.
Do not use inverters for driving motors equipped with series-connected
brakes.
Geared motors If the power transmission mechanism uses an oil-lubricated gearbox or
speed changer/reducer, then continuous motor operation at low speed
may cause poor lubrication. Avoid such operation.
Synchronous mo-
tors The PG interface card (option) corresponding to the pulse encoder spec-
fication is necessary. Read PG interface card (option) manual.
Single-phase
motors Single-phase motors are not suitable for inverter-driven variable speed
operation. Use three-phase motors.
Environ-
mental con-
ditions
Installation loca-
tion
Use the inverter within the ambient temperature range from -10 to +45°C.
The heat sink and braking resistor of the inverter may become hot under
certain operating conditions, so install the inverter on nonflammable ma-
terial such as metal.
Ensure that the installation location meets the environmental conditions
specified in Chapter 2, Section 2.1 "Operating Environment."

vi
Combina-
tion with
peripheral
devices
Installing an
MCCB or
RCD/ELCB
Install a recommended molded case circuit breaker (MCCB) or resi-
dual-current-operated protective device (RCD)/earth leakage circuit
breaker (ELCB) (with overcurrent protection) in the primary circuit of the
inverter to protect the wiring. Ensure that the circuit breaker capacity is
equivalent to or lower than the recommended capacity.
Installing an MC
in the secondary
circuit
If a magnetic contactor (MC) is mounted in the inverter's output (second-
ary) circuit, ensure that both the inverter and the motor are completely
stopped before you turn the MC on or off.
Remove a surge killer built-in the MC.
Installing an MC
in the primary
circuit
Do not turn the magnetic contactor (MC) in the primary circuit ON or OFF
more than once an hour as an inverter failure may result.
If frequent starts or stops are required during motor operation, use FWD /
REV signals.
Protecting the
motor
The electronic thermal function of the inverter can protect the motor. The
operation level and the motor type (general-purpose motor, inverter motor)
should be set. For high-speed motors or water-cooled motors, set a small
value for the thermal time constant and protect the motor.
If you connect the motor thermal relay to the motor with a long wire, a
high-frequency current may flow into the wiring stray capacitance. This
may cause the relay to trip at a current lower than the set value for the
thermal relay. If this happens, lower the carrier frequency.
Discontinuance
of power-factor
correcting capa-
citor
Do not mount power-factor correcting capacitors in the inverter’s primary
circuit. (Use the DC reactor to improve the inverter power factor.) Do not
use power-factor correcting capacitors in the inverter’s output (secondary)
circuit. An overcurrent trip will occur, disabling motor operation.
Discontinuance
of surge killer Do not connect a surge killer to the inverter's output (secondary) circuit.
Reducing noise Use of a filter and shielded wires is typically recommended to satisfy EMC
Directives.
Measures against
surge currents
If an overvoltage trip occurs while the inverter is stopped or operated under
a light load, it is assumed that the surge current is generated by open/close
of the phase-advancing capacitor in the power system.
* Connect a DC reactor to the inverter.
Megger test
When checking the insulation resistance of the inverter, use a 500 V
megger and follow the instructions contained in Chapter 7, Section 7.5
"Insulation Test."
Wiring
Control circuit
wiring length
When using remote control, limit the wiring length between the inverter and
operator box to 20 m or less and use twisted pair or shielded wire.
Wiring length
between inverter
and motor
If long wiring is used between the inverter and the motor, the inverter will
overheat or trip as a result of overcurrent (high-frequency current flowing
into the stray capacitance) in the wires connected to the phases. Ensure
that the wiring is shorter than 20 m. If this length must be exceeded, lower
the carrier frequency.
Wiring size Select wires with a sufficient capacity by referring to the current value or
recommended wire size.
Wiring type When several inverters drive motors, do not use one multicore cable in
order to connect several inverters with motors.
Grounding Securely ground the inverter using the grounding terminal.

vii
Selecting
inverter
capacity
Driving gener-
al-purpose motor
Select an inverter according to the applicable motor ratings listed in the
standard specifications table for the inverter.
When high starting torque is required or quick acceleration or deceleration
is required, select an inverter with a capacity one size greater than the
standard.
Driving special
motors
Select an inverter that meets the following condition:
Inverter rated current > Motor rated current
Transpor-
tation and
storage
Halogen compounds such as methyl bromide used in fumigation corrodes some parts inside the
inverter. When exporting an inverter built in a panel or equipment, pack them in a previously
fumigated wooden crate. When packing an inverter alone for export, use a laminated veneer
lumber (LVL).
When transporting or storing inverters, follow the procedures and select locations that meet the
environmental conditions listed in Chapter 1, Section 1.3 "Transportation" and Section 1.4
"Storage Environment."

1.3 Transportation
• When carrying an inverter, always support its bottom at the front and rear sides with both hands. Do not hold
covers or individual parts only. You may drop the inverter or break it.
1.4 Storage Environment
1.4.1 Temporary storage
Store the inverter in an environment that satisfies the requirements listed in Table 1.1.
Table 1.1 Environmental Requirements for Storage and Transportation
Item Requirements
Storage temperature *1-25 to +65°C A location where the inverter is not subject to abrupt changes in
temperature that would result in the formation of condensation or ice.
Relative humidity 5 to 95% *2
Atmosphere The inverter must not be exposed to dust, direct sunlight, corrosive or flammable gases,
oil mist, vapor, water drops or vibration. The atmosphere must contain only a low level of
salt. (0.01 mg/cm2or less per year)
Atmospheric pressure 86 to 106 kPa (in storage)
70 to 106 kPa (during transportation)
*1Assuming a comparatively short storage period (e.g., during transportation or the like).
*2Even if the humidity is within the specified requirements, avoid such places where the inverter will be subjected to
sudden changes in temperature that will cause condensation to form.
Precautions for temporary storage
(1) Do not leave the inverter directly on the floor.
(2) If the environment does not satisfy the specified requirements, wrap the inverter in an airtight vinyl sheet or
the like for storage.
(3) If the inverter is to be stored in an environment with a high level of humidity, put a drying agent (such as silica
gel) in the airtight package described in item (2).
1.4.2 Long-term storage
The long-term storage methods for the inverter vary largely according to the environment of the storage site.
General storage methods are described below.
(1) The storage site must satisfy the requirements specified for temporary storage.
However, for storage exceeding three months, the ambient temperature should be within the range from -10
to +30 °C. This is to prevent the electrolytic capacitors in the inverter from deteriorating.
(2) The inverter must be stored in a package that is airtight to protect it from moisture. Include a drying agent
inside the package to maintain the relative humidity inside the package to within 70%.
(3) If the inverter has been installed in the equipment or control board at a construction site where it may be
subjected to humidity, dust or dirt, then remove the inverter and store it in a suitable environment specified in
Table 1.1.
Precautions for storage over 1 year
If the inverter will not be powered on for a long time, the property of the electrolytic capacitors may deteriorate.
Power the inverters on once a year and keep them on for 30 to 60 minutes. Do not connect the inverters to motors
or run the motor.

2.2 Installing the Inverter
(1) Mounting base
The temperature of the heat sink will rise up to approx. 90°C during
operation of the inverter, so the inverter should be mounted on a base
made of material that can withstand temperatures of this level.
Install the inverter on a base constructed from metal or other
non-flammable material.
A fire may result with other material.
(2) Clearances
Ensure that the minimum clearances indicated in Figure 2.1 are
maintained at all times. When installing the inverter in the enclosure
of your system, take extra care with ventilation inside the enclosure
as the temperature around the inverter will tend to increase. Do not
install the inverter in a small enclosure with poor ventilation.
Further, do not install two or more inverters in single equipment or in
an enclosure.

(Note 1) Do not install the inverter in
an environment where it may be
exposed to cotton waste or moist dust
or dirt which will clog the heat sink in the
inverter. If the inverter is to be used in
such an environment, install it in the
enclosure of your system or othe
r
dustproof containers.
(Note 2) If you use the inverter in an
altitude above 1000 m, you should appl
y
an output current derating factor as
listed in Table 2.2.

When employing external cooling
A
t the shipment time, the inverter is set up for mount inside your
equipment or enclosure so that cooling is done all internally.
To improve cooling efficiently, you can take the heat sink out of the
equipment or the enclosure (as shown on the right) so that cooling
is done both internally and externally (this is called "external
cooling").
To set up inverters with a capacity of 22 kW or below for "external
cooling," add the optional mounting adapter; to set up ones with a
capacity of 30 kW or above, change the position of the top and
bottom mounting bases as shown below.
For details about the optional mounting adapter, refer to the
Mounting Adapter for External Cooling "PB-F1" Installation
Manual (INR-SI47-0880).
In external cooling, the heat sink, which dissipates about 70% of
the total heat (total loss) generated into air, is situated outside the
equipment or the enclosure. As a result, much less heat is
radiated inside the equipment or the enclosure.
In an environment with high humidity or a lot of fibrous dust,
however, do not use external cooling, which tends to clog the heat
sink.
Figure 2.2 External Cooling
Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter or from accumulating on the heat sink.
This may result in a fire or accident.
To utilize external cooling for inverters with a capacity of 30 kW, change the position of the top and bottom
mounting bases from the edge to the center of the inverter as instructed on the next page.
Screws differ in size, length and count for each inverter. Be sure to refer to the table below.

1) Remove all of the base fixing screws from the top and bottom of the inverter. Also remove the case fixing
screws from the top. (The case fixing screws are not necessary in external cooling. Store them for future
use. On the bottom are no case fixing screws.)
2) Secure the top mounting base to the center of the inverter with the base fixing screws, using case fixing
screw holes.
3) Secure the bottom mounting base to the center of the inverter with the base fixing screws.

(3) Mounting direction
Horizontal layout is recommended when two or more inverters are to be installed in an equipment or enclosure.
As long as the ambient temperature is 40°C or lower, inverters may be mounted side-by-side without any gap
between them. If it is necessary to mount the inverters vertically, install a partition plate or the like between the
inverters so that any heat radiating from an inverter will not affect the one/s above.
Do not mount the inverter upside down or horizontally. Doing so will reduce the heat dissipation
efficiency of the inverter and cause the overheat protection function to operate, so the inverter will not
run.
(4) Solving abnormal vibration after installation
If any vibration in the surroundings reaches the inverter and causes abnormal vibration to the cooling fan(s) or
the keypad, fix them firmly using the fixing screws provided as accessories.
