Guideline for Suppressing Harmonics in Home Electric and General-
purpose Appliances
Single-phase 200 V class series with 2.2 kW or less were once subject to the "Japanese
Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances"
(established in September 1994 and revised in October 1999), published by the Ministry of
International Trade and Industry (currently the Ministry of Economy, Trade and Industry (METI)).
Since the revision of the guideline in January 2004, however, these inverters have no longer
been subject to the guideline. The individual inverter manufacturers have voluntarily employed
harmonics suppression measures.

Safety precautions
Read this manual thoroughly before proceeding with installation, connections (wiring),
operation, or maintenance and inspection. Ensure you have sound knowledge of the device
and familiarize yourself with all safety information and precautions before proceeding to
operate the inverter.
Safety precautions are classified into the following two categories in this manual.
Failure to heed the information indicated by this
symbol may lead to dangerous conditions, possibly
resulting in death or serious bodily injuries.
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
• FVR-Micro is designed to drive a three-phase induction motor. Do not use it for
single-phase motors or for other purposes.
Fire or an accident could occur.
• FVR-Micro may not be used for a life-support system or other purposes directly related
to the human safety.
• Though FVR-Micro 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.
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.

4
• 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 current range.
• Use wires in the specified size.
• When wiring the inverter to the power supply of 500 kVA or more, be sure to connect an
optional AC reactor (ACR).
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.
• Be sure to connect the grounding wires without fail.
Otherwise, electric shock or fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power off.
• Ground the inverter in compliance with the national or local electric code.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter body.
Otherwise, electric shock or injuries could occur.
• 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).

5
• Generally, control signal wires are not reinforced insulation. If they accidentally touch
any of live parts in the main circuit, 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 hot high voltage lines.
Doing so could cause an accident or electric shock.
• 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 before turning the power on. Do not remove
the cover 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 depending 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 accelera-
tion/deceleration time or frequency different from the set ones. Design the machine so
that safety is ensured even in such cases.
Otherwise an accident could occur.
• The STOP key is only effective when function setting (Function code F02) has been es-
tablished to enable the STOP key. Prepare an emergency stop switch separately. If you
disable the STOP key priority function and enable operation by external commands, you
cannot emergency-stop the inverter using the STOP key on the built-in keypad.
• If an alarm reset is made with the operation signal turned on, a sudden start will occur.
Ensure that the operation signal is turned off in advance.
Otherwise an accident could occur.

6
• If you enable the "restart mode after momentary power failure" (Function code F14 = 4 or
5), then the inverter automatically restarts running the motor when the power is recovered.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• If you set the function codes wrongly or without completely understanding this instruction
manual, the motor may rotate with a torque or at a speed not permitted for the machine.
An accident or injuries could occur.
• Do not touch the inverter terminals while the power is applied to the inverter even if the
inverter stops.
Doing so could cause electric shock.
• Do not turn the main circuit power on or off in order to start or stop inverter operation.
Doing so could cause failure.
• Do not touch the heat sink or braking resistor 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.
Maintenance and inspection, and parts replacement
• Turn the power off and wait for at least five minutes before starting inspection. Further,
check that the LED monitor is unlit.
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.

7
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.

Chapter 2 MOUNTING AND WIRING OF THE INVERTER
2.1 Operating Environment
Install the inverter in an environment that satisfies the requirements listed in Table 2.1.
Table 2.1 Environmental Requirements Table 2.2 Output Current Derating Factor in
Relation toAltitude
Altitude Output current
derating factor
1000 m or lower 1.00
1000 to 1500 m 0.97
1500 to 2000 m 0.95
2000 to 2500 m 0.91
2500 to 3000 m 0.88
(Note 1) When inverters are mounted side-
by-side without any gap between them, the
ambient temperature should be within the
range from -10 to +40°C.
(Note 2) 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
panel of your system or other dustproof
containers.
(Note 3) If you use the inverter in an altitude
above 1000 m, you should apply an output
current derating factor as listed in Table 2.2.
2.2 Installing the Inverter
(1) Mounting base
The temperature of the heat sink may 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.
Top 100 mm
Left Right
Install the inverter on a base made of metal or
other non-flammable material.
A fire may result with other material.
10 mm 10 mm
(2) Clearances
Ensure that the minimum clearances indicated in
Figure 2.1 are maintained at all times. When
installing the inverter in the panel of your system,
take extra care with ventilation inside the panel as
the temperature around the inverter tends to
increase.

When mounting two or more inverters
When mounting two or more inverters in the same unit or panel, basically lay them out side by
side. As long as the ambient temperature is 40°C or lower, inverters can be mounted side by side
without any clearance between them. When mounting the inverters necessarily, one above the
other be sure to separate them with a partition plate or the like so that any heat radiating from an
inverter will not affect the one(s) above.
(3) Mounting direction
Secure the inverter to the mounting base with four screws or bolts (M4) sothat the FVR-Micro logo
faces outwards. (FVR0.4AS1S-7 and FVR0.75AS1S-7 use two screws or bolts.) Tighten those
screws or bolts perpendicular to the mounting base. (Maximum torque is 0.6N∙m)
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.
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.
2.3 Wiring
Follow the procedure below. (In the following description, the inverter has already been
installed.)
2.3.1 Removing and mounting the terminal block covers
(1) Loosen the screw securing the control circuit terminal block cover.
(2) Insert your finger in the cutout (near "PULL") in the bottom of the control circuit terminal
block cover, then pull the cover towards you.
(3) Hold both sides of the main circuit terminal block cover between thumb and forefinger and
slide it towards you.
(4) After performing wiring, mount the main circuit terminal block cover and control circuit
terminal block cover in the reverse order of removal.

2.3.4 Wiring precautions
Follow the rules below when performing wiring for the inverter.
(1) Make sure that the source voltage is within the rated voltage range specified on the nameplate.
(2) Be sure to connect the power wires to the main circuit power input terminals L1/R, L2/S and
L3/T (for three-phase voltage input) or L1/L and L2/N (for single-phase voltage input) of
the inverter. If the power wires are connected to other terminals, the inverter will be damaged
when the power is turned on.
(3) Always connect the grounding terminal to prevent electric shock, fire or other disasters
and to reduce electric noise.
(4) Use crimp terminals covered with insulated sleeves for the main circuit terminal wiring to
ensure a reliable connection.
(5) Keep the power supply wiring (primary circuit) and motor wiring (secondary circuit) of the
main circuit, and control circuit wiring as far away as possible from each other.
• 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 related current 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.
• Be sure to connect the grounding wires without fail.
Otherwise, electric shock or fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power off.
• Ground the inverter in compliance with the national or local electric code.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter body.
Otherwise, electric shock or injuries could occur.
• 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).

*2 Perform wiring as necessary.
Figure 2.3 Wiring Procedure for Peripheral Equipment
2-7

The wiring procedure for the FVR0.75AS1S-4 is given below as an example. For other inverter
types, perform wiring in accordance with their individual terminal arrangement.
①
Grounding terminal ( G)
Be sure to ground either of the two grounding terminals for safety and noise reduction. It is
stipulated by the Electric Facility Technical Standard that all metal frames of electrical
equipment must be grounded to avoid electric shock, fire and other disasters.
Grounding terminals should be grounded as follows:
1) Ground the inverter in compliance with the national or local electric code.
2) Connect a thick grounding wire with a large surface area. Keep the wiring length as short
as possible.
② Inverter output terminals, U, V, W and grounding terminal ( G)
1) Connect the three wires of the three-phase motor to terminals U, V, and W, aligning phases
each other.
2) Connect the grounding wire of terminals U, V, and W to the grounding terminal ( G).
- The wiring length between the inverter and motor should not exceed 50 m. If it exceeds
50 m, it is recommended that an output circuit filter (option) be inserted.
- Do not use one multicore cable to connect several inverters with motors.
• Do not connect a phase-advancing capacitor or surge absorber to the inverter’s
output lines (secondary circuit).
• If the wiring length is long, the stray capacitance between the wires will increase,
resulting in an outflow of the leakage current. It will activate the overcurrent
protection, increase the leakage current, or will not assure the accuracy of the
current display. In the worst case, the inverter could be damaged.
