Precautions for use
Driving a 400 V
general-purpose
motor
When driving a 400V 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.
Torque
characteristics
and temperature
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 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).
In running
general-
purpose
motors
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.
High-speed
motors 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.
Explosion-proof
motors When driving an explosion-proof motor with an inverter, use a combination of a motor and an
inverter that has been approved in advance.
Submersible
motors and
pumps
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.
Brake motors
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, the brake will not work.
Do not use inverters for driving motors equipped with series-connected brakes.
In running
special
motors
Geared motors 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.
Synchronous
motors It is necessary to take special measures suitable for this motor type. Contact your Fuji Electric
representative for details.
In running
special
motors Single-phase
motors
Single-phase motors are not suitable for inverter-driven variable speed operation. Use three-
phase motors.
In the event of a single phase supply to the inverter, a three phase motor must still be used as the
inverter outputs three phase only.
Environ-
mental
conditions
Installation
location
Use the inverter within the ambient temperature range from -10 to +50°C.
The heat sink and braking resistor of the inverter may become hot under certain operating
conditions, 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."
Installing an
MCCB or
RCD/ELCB
Install a recommended moulded case circuit breaker (MCCB) or residual-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 rated current is
equivalent to or lower than the recommended rated current.
Installing an MC
in the secondary
circuit
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.
Do not install magnetic contactors with built-in surge killer on the output of the inverter (secondary
circuit).
Installing an MC
in the primary
circuit
Do not turn the magnetic contactor (MC) in the primary circuit ON or OFF more than once per
hour as an inverter failure may result.
If frequent starts or stops are required during motor operation, use terminal [FWD]/[REV] signals
or the RUN/STOP key.
Combina-
tion with
peripheral
devices
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 or use the output circuit
filter (OFL).

Chapter 1: Safety Information
_______________________________________________________________________________________________________________ 5
Discontinuance
of power
capacitor for
power factor
correction
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.
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 Directive.
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 power capacitor for power
factor correction in the power system.
* Connect a DC reactor to the inverter.
Combina-
tion with
peripheral
devices
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" of FRENIC Multi Instruction
Manual (INR-SI47-1094-E).
Control circuit
wiring length When using remote control, limit the wiring length between the inverter and operator panel to 20 m or less and use twisted pair or shielded cable.
Wiring length
between inverter
and motor
If a long cable run is required between the inverter and the motor, the inverter may overheat or trip
as a result of overcurrent (high-frequency current flowing into the stray capacitance) in the cables
connected to the phases. Ensure that the wiring is shorter than 50 m. If this length must be
exceeded, lower the carrier frequency or mount an output circuit filter (OFL).
Wiring size Select cables 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.
Wiring
Grounding Securely ground the inverter using the grounding terminal.
Driving
general-purpose
motor
Select an inverter according to the nominal applied motor rating 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 one size larger capacity than the standard.
Selecting
inverter
capacity Driving special
motors Select an inverter that meets the following condition:
Inverter rated current > Motor rated current
Transpor-
tation and
storage
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" of FRENIC Multi
Instruction Manual (INR-SI47-1094-E).
1.2 Conformity to European standards
The CE marking on Fuji Electric products indicates that they comply with the essential requirements of the
Electromagnetic Compatibility (EMC) Directive 89/336/EEC issued by the Council of the European Communities and
the Low Voltage Directive 73/23/EEC.
Inverters with built-in EMC filter that bear a CE marking are in conformity with EMC directives. Inverters having no
built-in EMC filter can be in conformity with EMC directives if an optional EMC compliant filter is connected to them.
General purpose inverters are subject to the regulations set forth by the Low Voltage Directive in the EU. Fuji Electric
declares the inverters bearing a CE marking are compliant with the Low Voltage Directive.
FRENIC Multi inverters are in accordance with the regulations of following council directives and their amendments:
EMC Directive 89/336/EEC (Electromagnetic Compatibility)
Low Voltage Directive 73/23/EEC (LVD)
For assessment of conformity the following relevant standards have been taken into consideration:
EN61800-3:2004
EN50178:1997

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 panel of your system, take extra care with ventilation
inside the panel as the temperature around the inverter will tend to increase. Do not
install the inverter in a small panel with poor ventilation.

(Note 1) When inverters are mounted side-
by-side without any gap between them (less
than 5.5 kW), 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 you
r
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.

Chapter 3: Mechanical Installation
_______________________________________________________________________________________________________________ 7
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
or lower, inverters can be mounted side-by-side without any gap between them (only
for inverters with a capacity of less than 5.5 kW).
When employing external cooling
At the shipment time, the inverter is set up for mount inside 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 in Figure 2.2) 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 5.5 kW or above.
In an environment with high humidity or high levels of fibrous dust, do not use
external cooling, as this will clog the heat sink.
For details, refer to the Mounting Adapter for External Cooling "PB-F1/E1"
Installation Manual (INR-SI47-0880a).
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.

- Since low level analogue signals are used, these signals are especially susceptible to the external noise effects. Route the
wiring as short as possible (within 20 m) and use shielded wires. In principle, ground the shielded sheath of wires; if effects of
external inductive noises are considerable, connection to terminal [11] may be effective. As shown in Figure 3.7, ground the
single end of the shield to enhance the shield effect.
- Use a twin contact relay for low level signals if the relay is used in the control circuit. Do not connect the relay's contact to
terminal [11].
- When the inverter is connected to an external device outputting the analogue signal, a malfunction may be caused by electric
noise generated by the inverter. If this occurs, connect a ferrite core (a toroidal core or an equivalent) to the device outputting
the analogue signal and/or connect a capacitor having the good cut-off characteristics for high frequency between control
signal wires as shown in Figure 2.14.
- Do not apply a voltage of +7.5 VDC or higher to terminal [C1] when you assign the terminal [C1] to C1 function. Doing so
could damage the internal control circuit.

(2) Remove the keypad from the standard RJ-45 connector, and connect the RS-485 communications cable to
control the inverter through the PC or PLC (Programmable Logic Controller). Refer to Section 3.5, "Setting
up the slide switches" for setting of the terminating resistor.
Figure 3.14 RJ-45 Connector and its Pin Assignment*
* Pins 1, 2, 7, and 8 are exclusively assigned to power lines for the standard keypad and multi-function
keypad, so do not use those pins for any other equipment.
• Route the wiring of the control circuit terminals as far from the wiring of the main circuit as possible. Otherwise electric noise may
cause malfunctions.
• Fix the control circuit wires inside the inverter to keep them away from the live parts of the main circuit (such as the terminal block of
the main circuit).
• The RJ-45 connector pin assignment on the FRENIC-Multi series is different from that on the FVR-E11S series. Do not connect to the
keypad of the FVR-E11S series of inverter. Doing so could damage the internal control circuit.
Mounting the interface printed circuit board (interface PCB)
• Usually, you do not need to remove the interface PCB. However, in the case you remove the interface PCB, be sure when reinstalling
it to mount the interface PCB by locating the hooks provided on the interface PCB into the inverter until you hear a click.

3.4 Connection diagram
The diagram below shows a basic connection example for running the inverter with terminal commands.
(Note 1) When connecting an optional DC reactor (DCR), remove the jumper bar from the terminals [P1] and [P (+)].
(Note 2) Install a recommended moulded-case circuit breaker (MCCB) or an earth-leakage circuit-breaker (ELCB) (with an
overcurrent protection function) in the primary circuit of the inverter to protect wiring. At this time, ensure that the circuit
breaker capacity is equivalent to or lower than the recommended capacity.
(Note 3) Install a magnetic contactor (MC) for each inverter to separate the inverter from the power supply, apart from the MCCB or
ELCB, when necessary.
Connect a surge killer in parallel when installing a coil such as the MC or solenoid near the inverter.
