little salt in the atmosphere.
86～106kPa (During storage)
Atmospheric pressure 70～106kPa (During transportation)
Note 1: The storage temperature is for a short time during transportation or the like.
Note 2: ven if the humidity is within the requirements of the specifications, places with abrupt
temperature changes are subject to condensation or freezing. Avoid storing the inverter in
such places.
(1) Do not place the inverter directly on the floor.
(2) If the ambient atmosphere is adverse, wrap the inverter in a vinyl sheet or the like when storing.
(3) If humidity may give an ill effect, add a drying agent (such as silica gel) in the package prepared
as described in item (2).
The long-term storage method of the inverter varies largely according to the environment of the
storage site. General storage methods are described below.
(1) The storage site must satisfy the requirements of specifications for temporary storage.
However, for storage exceeding three months, the upper limit of the ambient temperature shall
not exceed 30 °C. This is for the prevention of deterioration of electrolytic capacitors left turned
off.
(2) The package must be air tight so that moisture will not enter. Add a drying agent inside the
package to contain the relative humidity inside the package within 70%.
(3) The inverter installed on a unit or control panel and left is likely to be exposed to moisture and
dust. If this is the case, remove the inverter and move it to a preferable environment.
(4) lectrolytic capacitors left turned off for an extended period of time deteriorate. Do not store for
one year or more without turning the power on.

1m/s2 to 200 Hz
2-2 Installation Method
(1) Tightly mount the inverter in the upright position on a
rigid structure so that the "FVR-E11" characters face
front. Avoid mounting the inverter upside down or
avoid mounting horizontally.
(2) Allow clearances for cooling wind shown in Fig. 2-2-1
to cool down the inverter which generates heat
during operation. The generated heat is radiated
upward. Do not install the inverter below a heat
sensitive device.
(3) The temperature of the heat sink rises to about 90
degrees C during operation of the inverter. Mount the
inverter on a base made of a material withstanding
the temperature rise.
！
！！
！WARNING Install the inverter on a nonflammable material such as
metal.
Other ise fire could occur.
(4) When installing the inverter inside a control panel or the like, take full consideration for
ventilation so that the ambient temperature of the inverter does not exceed the specification
requirements. Do not install the inverter in a poorly ventilated small enclosure.
( ) When storing multiple inverters inside a single unit or inside a control panel, horizontal
installation is recommended to reduce mutual temperature effects. When an vertical layout is
adopted for an unavoidable reason, install a partition plate or the like between inverters to isolate
the heat of the lower inverter.
！
！！
！
CAUTION
Do not allow lint, paper, wood chips, dust, metallic chips or other foreign matter in
the inverter or do not allow them attached to the heat sink.
Other ise fire or an accident could occur.

2-3 Connection
Remove the control terminal block cover to connect the control terminal block. Remove the main
circuit terminal block cover to connect the main circuit terminal block. Correctly connect cables
taking care of the following precautions.
2-3-1 Basic Connection
(1) Be sure to connect the power cables to main circuit power terminals L1/R, L2/S and L3/T or
L1/L,L2/N of the inverter. If the power cables are connected to other terminals, the inverter will
be broken. As well, check the source voltage for the allowable voltage range specified on the
nameplate and so on.
(2) Connect the grounding terminal without fail according to national or local electric code to prevent
electric shock, fire or other disasters and to reduce electric noise.
(3) Use reliable crimp terminals for connection of cables to the terminals.
(4) After finishing wiring, check the following.
a. Check if the cables are connected correctly.
b. Check if there is no failure of connection.
c. Check if terminals or cables are short circuited or there is a ground fault.
( ) To change connection of an inverter having been turned on
The smoothing capacitor in the direct current part of the main circuit takes time to be discharged
after it is turned off. To avoid danger, check the DC voltage (across main circuit terminals P (+)
and N (-)) for a safety voltage (2 Vdc or lower) using a multi-meter, after the charge lamp is unlit.
Wait until the residual voltage is discharged before shorting a circuit, to avoid being hit by sparks
caused by the voltage (electric charge).

Connects a 1-phase power supply.
U,V,W Inverter output Connects a 3-phase induction motor.
P1,P(+) For DC reactor Connects an optional DC reactor.
P(+),DB For external braking
resistor
Connects an optional external braking resistor.
P(+),N(-) DC link circuit terminal Connected to DC link circuit.
G grounding Grounding terminal of the inverter chassis (housing).
Connect to the protective ground.
(1) Main circuit power input terminal (L1/R, L2/S, L3/T,L1/L,L2/N)
a. Connect the main circuit power input terminals to the power supply through a circuit breaker
for circuit (wiring) protection or an earth leakage breaker. There is not need to match the
phase sequence.
b. It is recommended to connect a magnetic contactor to disconnect the inverter from the power
supply to prevent a failure or accident from becoming serious upon activation of the
protective function of the inverter.
c. Do not turn the main circuit power supply on or off to start or stop the inverter. Instead, use
control circuit terminals FWD and REV or the RUN and STOP keys on the keypad panel. If it
is unavoidable to turn the main circuit power supply on or off to start or stop the inverter, limit
the frequency to once an hour or fewer.
d. Do not connect to a single-phase power supply for 3-phase input inverter.
(2) Inverter output terminals (U, V, W)
a. Connect these terminals to a 3-phase motor with the correct phase sequence. If the direction
of rotation does not match the operation direction, change arbitrary two cables among the U,
V and W phases.
b. Do not connect a phase advance capacitor or surge absorber to the inverter output.
c. If the wiring length between the inverter and the motor is extremely long, the stray capacity
between cables causes a high frequency current, possibly tripping the inverter due to an
overcurrent, increasing the leakage current, or deteriorating the current detection accuracy to
cause deterioration of the performance or other phenomena. To prevent such trouble, limit
the wiring length of the motor to 0 m for 4.0 kW or a smaller output or to 100 m for a larger
output.
Note: When a thermal relay is installed in the path between the inverter and the motor, or especially
in the case of a 400V system, the thermal relay may malfunction even with a wiring length
shorter than 0 m. In such a case, add an OFL filter or lower the Motor sound adjustment
(carrier frequency) of the inverter. ... Function code F26 Motor sound adjustment.

2-
(3) DC reactor connecting terminals (P1, P (+))
a. Use this terminal to connect a DC reactor (option).
Remove the jumper connected in the factory before
connecting the DC reactor.
b. Do not remove the jumper if no DC reactor is used.
Cut the barrier in the main circuit terminal block cover
for the P1, P (+), DB and N (-) cable port using nippers
or the like when connecting wiring.
(4) External braking resistor connecting terminals (P (+), DB)
E11S is not equipped with a braking resistor. An external
braking resistor (option) is necessary for frequent
operation or heavy duty inertia load operation to
enhance the braking performance.
a. Connect the P (+) and DB terminals of the
external braking resistor to the P (+) and DB
terminals of the inverter.
b. Arrange devices so that the wiring length is within
m and twist or closely (in parallel) place the two
cables.
( ) Inverter grounding terminal ( G )
Ground the grounding terminal G for safety and noise reduction without fail. The metallic frame
of electrical equipment must be grounded in accordance with national or local electric code to
avoid electric shock, fire and other disasters.
