Application

• FRENIC-Multi 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.

• FRENIC-Multi may not be used for a life-support system or other purposes directly related
to the human safety.

• Though FRENIC-Multi 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.

i

Installation

• Install the inverter on a nonflammable material such as metal.
Otherwise fire could occur.

• Do not place flammable object nearby.
Doing so could cause fire.

• 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 supply, insert a recommended molded case circuit
breaker (MCCB) or residual-current-operated protective device (RCD)/a ground fault
circuit interrupter (GFCI)(with overcurrent protection). Use the devices within the
recommended current range.

• Use wires in the specified size.

• When wiring the inverter to the power supply that is 500 kVA or more, be sure to connect
an optional DC reactor (DCR).

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.

• Ground the inverter in compliance with the national or local electric code.

Otherwise, electric shock 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.

ii

• 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 supply wires to output terminals (U, V, and W).

• Do not insert a braking resistor between terminals P (+) and N (-), P1 and N (-), P (+) and
P1, DB and N (-), or P1 and DB.

Doing so could cause fire or an accident.

• 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 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 auto-reset 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
acceleration/deceleration time or frequency different from the commanded ones. Design
the machine so that safety is ensured even in such cases.

Otherwise an accident could occur.

iii

• The key on the keypad is effective only when the keypad operation is enabled with
function code F02 (= 0, 2 or 3). When the keypad operation is disabled, prepare an
emergency stop switch separately for safe operations.

Switching the run command source from keypad (local) to external equipment (remote) by

turning ON the "Enable communications link" command LE disables the key. To
enable the key for an emergency stop, select the STOP key priority with function code
H96 (= 1 or 3).

• 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 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 and the FRENIC-Multi User's 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 (circuit breaker) ON or OFF in order to start or stop
inverter operation.

Doing so could cause failure.

• Do not touch the heat sink and 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.

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.

v

Conformity to the Low Voltage Directive in the EU

If installed according to the guidelines given below, inverters marked with CE or TÜV are considered
as compliant with the Low Voltage Directive 2006/95/EC.

1. The ground terminal G should always be connected to the ground. Do not use only a
residual-current-operated protective device (RCD)/a ground fault circuit interrupter (GFCI)*
as the sole method of electric shock protection. Be sure to use ground wires whose size is
greater than power supply lines.

With overcurrent protection.

*

2. When used with the inverter, a molded case circuit breaker (MCCB), residual­current-operated protective device (RCD)/a ground fault circuit interrupter (GFCI) or
magnetic contactor (MC) should conform to the EN or IEC standards.

3. When you use a residual-current-operated protective device (RCD)/a ground fault circuit
interrupter (GFCI) for protection from electric shock in direct or indirect contact power lines
or nodes, be sure to install type B of RCD/GFCI on the input (primary) of the inverter if the
power supply is three-phase 230/460 V. For single-phase 230 V power supply, use type A.

When you use no RCD/GFCI, take any other protective measure that isolates the electric

equipment from other equipment on the same power supply line using double or reinforced
insulation or that isolates the power supply lines connected to the electric equipment using
an isolation transformer.

4. The inverter should be used in an environment that does not exceed Pollution Degree 2
requirements. If the environment conforms to Pollution Degree 3 or 4, install the inverter in
an enclosure of IP54 or higher.

5. Install the inverter, AC or DC reactor, input or output filter in an enclosure with minimum
degree of protection of IP2X (Top surface of enclosure shall be minimum IP4X when it can
be easily accessed), to prevent human body from touching directly to live parts of these
equipment.

6. To make an inverter with no integrated EMC filter conform to the EMC directive, it is
necessary to connect an external EMC filter to the inverter and install them properly so that
the entire equipment including the inverter conforms to the EMC directive.

7. Do not connect any copper wire directly to grounding terminals. Use crimp terminals with tin
or equivalent plating to connect them.

8. To connect the three-phase or single-phase 230 V class series of inverters to the power
supply in Overvoltage Category III or to connect the three-phase 460 V class series of
inverters to the power supply in Overvoltage Category II or III, a supplementary insulation is
required for the control circuitry.

9. When you use an inverter at an altitude of more than 6600ft (2000 m), you should apply
basic insulation for the control circuits of the inverter. The inverter cannot be used at
altitudes of more than 9800ft (3000 m).

vi

Conformity to the Low Voltage Directive in the EU (Continued)

10. Use wires listed in IEC60364-5-52.

MCCB: Molded case circuit breaker RCD: Residual-current-operated protective device
GFCI: Ground fault circuit interrupter

*1 The frame size and model of the MCCB or RCD/GFCI (with overcurrent protection) will vary,

depending on the power transformer capacity. Refer to the related technical documentation for
details.

*2 The recommended wire size for main circuits is for the 70C(158F) 600 V PVC wires used at an

ambient temperature of 40C(104F).

*3 In the case of no DC reactor, the wire sizes are determined on the basis of the effective input

current calculated under the condition that the power supply capacity and impedance are 500 kVA
and 5%, respectively.

vii

Conformity to UL standards and Canadian standards (cUL certification)

If installed according to the guidelines given below, inverters marked with UL/cUL are considered as
compliant with the UL and CSA (cUL certified) standards.

1. Solid state motor overload protection (motor protection by electronic thermal overload relay)
is provided in each model.
Use function codes F10 to F12 to set the protection level.

2. Connect the power supply satisfying the characteristics shown in the table below as an
input power supply of the inverter. (Short circuit rating)

3. Use 75C(167F) Cu wire only.

4. Use Class 1 wire only for control circuits.

5. Field wiring connection must be made by a UL Listed and CSA Certified closed-loop
terminal connector sized for the wire gauge involved. Connector must be fixed using the
crimp tool specified by the connector manufacturer.

6. Short circuit rating

Suitable for use on a circuit capable of delivering not more than 100 kA rms symmetrical

amperes, 240 volts maximum for Three-phase or Single-phase 200 V input class when
protected by a Circuit Breaker having an interrupting rating not less than 100 kA rms
symmetrical amperes, 240 volts maximum.

Suitable for use on a circuit capable of not more than 100 kA rms symmetrical amperes, 480

volts maximum for Three-phase 400V input class when protected by a Circuit Breaker
having an interrupting rating not less than 100 kA rms symmetrical amperes, 480 volts

When driving a 460V general-purpose motor with an inverter
using extremely long wires, damage to the insulation of the
motor may occur. Use an output circuit filter (OFL) if
necessary after checking with the motor manufacturer. Fuji
motors do not require the use of output circuit filters because
of their reinforced insulation.

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.

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 abnormal vibration.

* The use of a rubber coupling or vibration-proof rubber is

recommended.

* Use the inverter's jump frequency control feature to skip

the resonance frequency zone(s).

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.

If the reference frequency is set to 120 Hz or more to drive a
high-speed motor, test-run the combination of the inverter
and motor beforehand to check for safe operation.

When driving an explosion-proof motor with an inverter, use a
combination of a motor and an inverter that has been
approved in advance.

These motors have a larger rated current than
general-purpose motors. Select an inverter whose rated
output current is greater than that of the motor.

These motors differ from general-purpose motors in thermal
characteristics. Set a low value in the thermal time constant
of the motor when setting the electronic thermal function.

For motors equipped with parallel-connected brakes, their
power supply for brake must be supplied from the primary
circuit. If the power supply for brake 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.

If the power transmission mechanism uses an oil-lubricated
gearbox or speed changer/reducer, then continuous
operation at low speed may cause poor lubrication. Avoid
such operation.

Protecting the
motor

It is necessary to take special measures suitable for this
motor type. Consult your Fuji Electric representative for
details.

Single-phase motors are not suitable for inverter-driven
variable speed operation. Use three-phase motors.

Even if a single-phase power supply is available, use a
three-phase motor as the inverter provides three-phase
output.

Use the inverter within the ambient temperature range from
–10C(14F) to +50C(122F).

The heat sink and braking resistor of the inverter may
become hot under certain operating conditions, so install the
inverter on nonflammable material such as metal.

Ensure that the installation location meets the environmental
conditions specified in Chapter 2, Section 2.1 "Operating
Environment."

Install a recommended molded case circuit breaker (MCCB)
or residual-current-operated protective device (RCD)/a
ground fault circuit interrupter (GFCI) (with overcurrent
protection) in the primary circuit of the inverter to protect the
wiring. Ensure that the circuit breaker rated current is
equivalent to or lower than the recommended rated current.

If a magnetic contactor (MC) is mounted in the inverter's
output (secondary) circuit for switching the motor to
commercial power or for any other purpose, ensure that both
the inverter and the motor are completely stopped before you
turn the MC ON or OFF.

Remove the magnet contactor (MC) already installed and
built-in surge killer from the inverter's output (secondary)
circuit before installing the MC to switch the motor power.

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 terminal [FWD]/[REV] signals or the /
key.

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 or use the output circuit
filter (OFL).

xii

Do not mount power capacitors for power factor correction in
the inverter’s primary circuit. (Use the DC reactor to correct
the inverter power factor.) Do not use power capacitors for
power factor correction in the inverter’s output (secondary)
circuit. An overcurrent trip will occur, disabling motor
operation.

Do not connect a surge killer to the inverter's output
(secondary) circuit.

Use of a filter and shielded wires is typically recommended to
satisfy EMC Directive.

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 power capacitor for
power factor correction 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."

When using remote control, limit the wiring length between
the inverter and operator panel to 66ft (20 m) or less and use
twisted pair or shielded wire.

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 164ft (50 m). If this length must be exceeded,
lower the carrier frequency or mount an output circuit filter.

Select wires with a sufficient capacity by referring to the
current value or recommended wire size.

When several inverters drive motors, do not use one
multicore cable in order to connect several inverters with
motors.

inside the inverter may be corroded by halogen compounds such as methyl
bromide used in fumigation.

When packing an inverter alone for export, use a laminated veneer lumber (LVL).

1.3 Transportation

• When carrying an inverter, always support its bottom at the right and left sides with both hands. Do
not hold covers or individual parts only.

• Avoid applying excessively strong force to the terminal block covers as they are made of plastic
and are easily broken.

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 *

Relative humidity 5 to 95% *2
Atmosphere

Atmospheric pressure 86 to 106 kPa (in storage)

1

*

Assuming a comparatively short storage period (e.g., during transportation or the like).

2

*

Even 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°C(14F) to +30°C(86F). 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 within 70%.

(3) If the inverter has been installed in the equipment or control panel 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 inverter to a motor or run the motor.

 When mounting two or more inverters

Horizontal layout is recommended when two or more
inverters are to be installed in the same unit or panel. 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. As
long as the ambient temperature is 40°C (104F) or lower,
inverters can be mounted side-by-side without any gap
between them (only for inverters with a capacity of less than

7.5 HP).

 When employing external cooling

your equipment or panel so that cooling is done all internally.
To improve cooling efficiently, you can take the heat sink out

of the equipment or the panel (as shown on the right) so that
cooling is done both internally and externally (this is called
"external cooling").

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 panel. As a result, much less
heat is radiated inside the equipment or the panel.

To take advantage of external cooling, you need to use the
external cooling attachment option for inverters with a
capacity of 7.5 HP or above.

In an environment with high humidity or a lot of fibrous dust,
however, do not use external cooling in an environment with
high humidity or a lot of fibrous dust, which tends to clog the
heat sink.



For details, refer to the Mounting Adapter for

External Cooling "PB-F1/E1" Installation Manual .

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.

2-2

reduce the heat

,

(3) Mounting direction

Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so
that the logo "FRENIC-Multi" can be seen from the front.

Do not mount the inverter upside down or horizontally. Doing so will
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
fans or the keypad, fix them firmly using the fixing screws provided as accessories.
