to high temperature, high humidity, condensation, dust, explosive gases, corrosive gases, flammable gases, grinding fluid
mist, or salt water. Otherwise, you run the risk of fire.
- The inverter is precision equipment. Do not allow it to fall or be subject to high impacts, step on it, or place a heavy load on
it. Doing so may cause the inverter to fail.
2. Wiring
WARNING
- Be sure to ground the inverter. Otherwise, you run the risk of electric shock or fire.
- Commit wiring work to a qualified electrician. Otherwise, you run the risk of electric shock or fire.
- Before wiring, make sure that the power supply is off. Otherwise, you run the risk of electric shock or fire.
- Perform wiring only after installing the inverter. Otherwise, you run the risk of electric shock or injury.
- Do not remove rubber bushings from the wiring section. Otherwise, the edges of the wiring cover may damage the wire,
resulting in a short circuit or ground fault.
CAUTION
- Make sure that the voltage of AC power supply matches the rated voltage of your inverter. Otherwise, you run the risk of
injury or fire.
- Do not input single-phase power into the inverter. Otherwise, you run the risk of fire.
- Do not connect AC power supply to any of the output terminals (U, V, and W). Otherwise, you run the risk of injury or fire.
- Do not connect a resistor directly to any of the DC terminals (PD, P, and N). Otherwise, you run the risk of fire.
- Connect an earth-leakage breaker to the power input circuit. Otherwise, you run the risk of fire.
- Use only the power cables, earth-leakage breaker, and magnetic contactors that have the specified capacity (ratings).
Otherwise, you run the risk of fire.
- Do not use the magnetic contactor installed on the primary and secondary sides of the inverter to stop its operation.
- Tighten each screw to the specified torque. No screws must be left loose. Otherwise, you run the risk of fire.
- Before operating, slide switch SW1 in the inverter, be sure to turn off the power supply. Otherwise, you run the risk of
electric shock and injury.
- Since the inverter supports two modes of cooling-fan operation, the inverter power is not always off, even when the cooling
fan is stopped. Therefore, be sure to confirm that the power supply is off before wiring. Otherwise, you run the risk of
electric shock and injury.

3. Operation
WARNING
- While power is supplied to the inverter, do not touch any terminal or internal part of the inverter, check signals, or connect
or
disconnect any wire or connector. Otherwise, you run the risk of electric shock or fire.
- Be sure to close the terminal block cover before turning on the inverter power. Do not open the terminal block cover while
power is being supplied to the inverter or voltage remains inside. Otherwise, you run the risk of electric shock.
- Do not operate switches with wet hands. Otherwise, you run the risk of electric shock.
- While power is supplied to the inverter, do not touch the terminal of the inverter, even if it has stopped. Otherwise, you run
the risk of injury or fire.
- If the retry mode has been selected, the inverter will restart suddenly after a break in the tripping status. Stay away from
the machine controlled by the inverter when the inverter is under such circumstances. (Design the machine so that human
safety can be ensured, even when the inverter restarts suddenly.) Otherwise, you run the risk of injury.
- Do not select the retry mode for controlling an elevating or traveling device because output free-running status occurs in
retry
mode. Otherwise, you run the risk of injury or damage to the machine controlled by the inverter.
- If an operation command has been input to the inverter before a short-term power failure, the inverter may restart
operation after the power recovery. If such a restart may put persons in danger, design a control circuit that disables the
inverter from restarting after power recovery. Otherwise, you run the risk of injury.
- The [STOP] key is effective only when its function is enabled by setting. Prepare an emergency stop switch separately.
Otherwise, you run the risk of injury.
- If an operation command has been input to the inverter before the inverter enters alarm status, the inverter will restart
suddenly when the alarm status is reset. Before resetting the alarm status, make sure that no operation command has been
input.
- While power is supplied to the inverter, do not touch any internal part of the inverter or insert a bar in it. Otherwise, you
run the risk of electric shock or fire.
CAUTION
- Do not touch the heat sink, which heats up during the inverter operation. Otherwise, you run the risk of burn injury.
- The inverter allows you to easily control the speed of motor or machine operations. Before operating the inverter, confirm
the capacity and ratings of the motor or machine controlled by the inverter. Otherwise, you run the risk of injury.
- Install an external brake system if needed. Otherwise, you run the risk of injury.
- When using the inverter to operate a standard motor at a frequency of over 60 Hz, check the allowable motor speeds with
the manufacturers of the motor and the machine to be driven and obtain their consent before starting inverter operation.
Otherwise, you run the risk of damage to the motor and machine.

2.1 Installation
CAUTION
- Install the inverter on a non-flammable surface, e.g., metal. Otherwise, you run the risk of fire.
- Do not place flammable materials near the installed inverter. Otherwise, you run the risk of fire.
- When carrying the inverter, do not hold its top cover. Otherwise, you run the risk of injury by dropping the
inverter.
- Prevent foreign matter (e.g., cut pieces of wire, sputtering welding materials, iron chips, wire, and dust) from
entering the inverter. Otherwise, you run the risk of fire.
- Install the inverter on a structure able to bear the weight specified in this Instruction Manual. Otherwise, you
run the risk of injury due to the inverter falling.
- Install the inverter on a vertical wall that is free of vibrations. Otherwise, you run the risk of injury due to the
inverter falling.
- Do not install and operate the inverter if it is damaged or its parts are missing. Otherwise, you run the risk of
injury.
- Install the inverter in a well-ventilated indoor site not exposed to direct sunlight. Avoid places where the
inverter is exposed to high temperature, high humidity, condensation, dust, explosive gases, corrosive gases,
flammable gases, grinding fluid mist, or salt water. Otherwise, you run the risk of fire.
- The inverter is precision equipment. Do not allow it to fall or be subject to high impacts, step on it, or place a
heavy load on it. Doing so may cause the inverter to fail.
Chapter 2 Installation and Wiring
2-2
2.1.1 Precautions for installation
(1) Transportation
The inverter uses plastic parts. When carrying the inverter, handle it carefully to prevent damage to the parts.
Do not carry the inverter by holding the front or terminal block cover. Doing so may cause the inverter to fall.
Do not install and operate the inverter if it is damaged or its parts are missing.
(2) Surface on which to install the inverter
The inverter will reach a high temperature (up to about 150°C) during operation. Install the inverter on a vertical
wall surface made of nonflammable material (e.g., metal) to avoid the risk of fire.
Leave sufficient space around the inverter. In particular, keep sufficient distance between the inverter and other heat
sources (e.g., braking resistors and reactors) if they are installed in the vicinity.
(3) Ambient temperature
Avoid installing the inverter in a place where the ambient temperature goes above or below the allowable range
(-10°C to +50°C), as defined by the standard inverter specification.
Measure the temperature in a position about 5 cm distant from the bottom-center point of the inverter, and check
that the measured temperature is within the allowable range.
Operating the inverter at a temperature outside this range will shorten the inverter life (especially the capacitor life).
(4) Humidity
Avoid installing the inverter in a place where the relative humidity goes above or below the allowable range (20% to
90% RH), as defined by the standard inverter specification.
Avoid a place where the inverter is subject to condensation.
Condensation inside the inverter will result in short circuits and malfunctioning of electronic parts. Also avoid places
where the inverter is exposed to direct sunlight.
(5) Ambient air
Avoid installing the inverter in a place where the inverter is subject to dust, corrosive gases, combustible gases,
flammable gases, grinding fluid mist, or salt water.
Foreign particles or dust entering the inverter will cause it to fail. If you use the inverter in a considerably dusty
environment, install the inverter inside a totally enclosed panel.

(6) Installation method and position
Install the inverter vertically and securely with screws or bolts on a surface that is free from vibrations and that can
bear the inverter weight. If the inverter is not installed vertically, its cooling performance may be degraded and
tripping or inverter damage may result.
(7) When mounting multiple inverters in an enclosure with a ventilation fan, carefully design the layout of the
ventilation fan, air intake port, and inverters. An inappropriate layout will reduce the inverter-cooling effect and
raise the ambient temperature. Plan the layout so that the inverter ambient temperature will remain within the
allowable range.
Position of ventilation fan
(8) Mounting in an enclosure
The internal fan releases the heat generated by the inverter from the upper part of the inverter. When it is
necessary to install a device above the inverter, please ensure that the device is protected against this heat.
When several inverters are mounted in the same cabinet the standard arrangement of the inverters is side-by-side
with certain space as shown in the figure on the left below. If the inverters must be mounted one above the other
in order to save the cabinet space or similar, the heat from the lower inverter may lead to temperature rise and
breakdown of the higher inverter. Please ensure that the heat generated by the lower inverter does not affect the
one above by installing a mechanical separation or similar (e.g. guide plate between the inverters as shown in the
figure below right).
When mounting several inverters in the same cabinet, design the cabinet so that the temperature inside the
cabinet does not exceed the allowable specific range for the inverter (by using increased ventilation and/or
enlarging the size of cabinet etc.)

(9) Reduction of enclosure size
If you mount the inverter inside an enclosure such that the heat sink of the inverter is positioned outside the
enclosure, the amount of heat produced inside the enclosure can be reduced and likewise the size of the enclosure.
Mounting the inverter in an enclosure with the heat sink positioned outside requires an optional dedicated special
metal fitting. To mount the inverter in an enclosure with the heat sink positioned outside, cut out the enclosure
panel according to the specified cutting dimensions. The cooling section (including the heat sink) positioned
outside the enclosure has a cooling fan. Therefore, do not place the enclosure in any environment where it is
exposed to waterdrops, oil mist, or dust.

2.2 Wiring
WARNING
- Be sure to ground the inverter. Otherwise, you run the risk of electric shock or fire.
- Commit wiring work to a qualified electrician. Otherwise, you run the risk of electric shock or fire.
- Before wiring, make sure that the power supply is off. Otherwise, you run the risk of electric shock or fire.
- Perform wiring only after installing the inverter. Otherwise, you run the risk of electric shock or injury.
- Do not remove rubber bushings from the wiring section. Otherwise, the edges of the wiring cover may damage
the wire, resulting in a short circuit or ground fault.
CAUTION
- Make sure that the voltage of AC power supply matches the rated voltage of your inverter. Otherwise, you run
the risk of injury or fire.
- Do not input single-phase power into the inverter. Otherwise, you run the risk of fire.
- Do not connect AC power supply to any of the output terminals (U, V, and W). Otherwise, you run the risk of
injury or fire.
- Do not connect a resistor directly to any of the DC terminals (PD, P, and N). Otherwise, you run the risk of fire.
- Connect an earth-leakage breaker to the power input circuit. Otherwise, you run the risk of fire.
- Use only the power cables, earth-leakage breaker, and magnetic contactors that have the specified capacity
(ratings). Otherwise, you run the risk of fire.
- Do not use the magnetic contactor installed on the primary and secondary sides of the inverter to stop its
operation.
- Tighten each screw to the specified torque. No screws must be left loose. Otherwise, you run the risk of fire.
- Before operating, slide switch SW1 in the inverter, be sure to turn off the power supply. Otherwise, you run the
risk of electric shock and injury.
- Since the inverter supports two modes of cooling-fan operation, the inverter power is not always off, even
when the cooling fan is stopped. Therefore, be sure to confirm that the power supply is off before wiring.
Otherwise, you run the risk of electric shock and injury.

About the emergency stop function (disabled by the factory setting)
- The emergency stop function shuts off the inverter output (i.e. stops the switching operation of the main circuit
elements) in response to a command from a hardware circuit via an intelligent input terminal without the operation
by internal CPU software.
Note: The emergency stop function does not electrically shut off the inverter but merely stops the switching operation
of the main circuit elements. Therefore, do not touch any terminals of the inverter or any power lines, e.g.,
motor cables. Otherwise, electric shock, injury, or ground fault may result.
- When the emergency stop function is enabled, intelligent input terminals 1 and 3 are used exclusively for this
function, and no other functions can be assigned to these terminals. Even if other functions have been assigned to
these terminals, these are automatically disabled and these terminals are used exclusively for the emergency stop
function.
Terminal [1] function:
This terminal always serves as the a (NO) contact for the reset (RS) signal.
This signal resets the inverter and releases the inverter from the trip due to emergency stop (E37.*).
Terminal [3] function:
This terminal always serves as the b (NC) contact for the emergency stop (EMR) signal.
This signal shuts off the inverter output without the operation by internal CPU software.
This signal makes the inverter trip due to emergency stop (E37.*).
Note: If intelligent input terminal 3 is left unconnected, the cable connected to the terminal is disconnected, or the
signal logic is improper, the inverter trips due to emergency stop (E37.*). If this occurs, check and correct the
wiring and signal logic, and then input the reset (RS) signal.
Only the reset (RS) signal input from intelligent input terminal [1] can release the inverter from tripping due to
emergency stop (E37.*). (The inverter cannot be released from the E37.* status by any operation from the
digital operator.)
- To enable the emergency stop function, set the slide lever of slide switch SW1 to ON. (With the factory setting, slide
switch SW1 is set to OFF to disable the function.)
Note: Before operating slide switch SW1, make sure that the input power supply is off.

*1 When function "18 (RS)" is assigned to the input terminal, "a/b (NO/NC)" selection is always "00 (NO)".
*2 When terminal setting "C003" is "64 (EMR)", terminal setting "C013" is always "01 (NC)".
*3 If function "18 (RS)" has been assigned to an intelligent input terminal other than intelligent input terminals [1] and [3] before slide
switch SW1 is set to ON, the input terminal setting for said terminal is automatically changed to "no (no function assigned)" when slide
switch SW1 is set to ON to prevent any duplication of terminal functions. Even if slide switch SW1 is subsequently returned to OFF, the
original function setting for said terminal will not be restored. If necessary, the original function will have to be re-assigned to said
terminal.
Example: If slide switch SW1 is set to ON when function "18 (RS)" has been assigned to input terminal 2 (by terminal setting "C002"),
terminal setting "C002" is changed to "no (no function assigned)," and function "18 (RS)" is assigned to input terminal 1 (by terminal
setting "C001").
Even if slide switch SW1 is subsequently returned to OFF, terminal [2] function "C002" and terminal [1] function "C001" will remain as
"no (no function assigned)" and "18 (RS)," respectively.
