(8) Application of caution labels
Do not install a power factor correction capacitor, surge absorber, or radio noise filter on the output side of this product. These devices may overheat or burn out.
The connection orientation of the output cables U, V, W to the motor affects the rotation direction of the motor.
Before starting operation, each parameter must be confirmed and adjusted. Failure to do so may cause some machines to make unexpected motions.
Stay away from the equipment when the retry function is set as it will restart suddenly after trip.
Since pressing key may not stop output depending on
the function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.
OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting inverter alarm with the start signal ON restarts the motor suddenly.
The inverter must be used for three-phase induction motors. Connection of any other electrical equipment to the product output may damage the equipment.
Do not modify the equipment. Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the product.
The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection.
Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise the life of the inverter decreases.
The effect of electromagnetic interference must be reduced by using a noise filter or by other means. Otherwise nearby electronic equipment may be affected.
Appropriate precautions must be taken to suppress harmonics. Otherwise power supply harmonics from the inverter may heat/damage the power factor correction capacitor and generator.
When driving a 400V class motor with the inverter, the motor must be an insulation-enhanced motor or measures must be taken to suppress surge voltage. Otherwise surge voltage, which is attributed to the length and thickness of wire, may occur at the motor terminals, causing the motor insulation to deteriorate.
When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations because all parameters return to the initial value.
The inverter can be easily set for high-speed operation. Before changing its setting, the performances of the motor and machine must be fully examined.
This product's brake function cannot be used as a mechanical brake. Use a separate device instead.
Perform an inspection and test operation of this product if it has been stored for a long period of time.
Static electricity in your body must be discharged before you touch the product. Otherwise the product may be damaged.
If you are installing the inverter to drive a three-phase device while you are contracted for lighting and power service, consult your electric power supplier.
CAUTION
CAUTION
WARNING
CAUTION
A safety backup such as an emergency brake must be provided for devices or equipment in a system to prevent hazardous conditions in case of failure of this product or an external device controlling this product.
If the breaker installed on the input side of this product trips, check for wiring faults (short circuits etc.) and damage to internal parts of this product. The cause of the trip must be identified and removed before turning ON the power of the breaker.

2 INSTALLATION AND WIRING
NOTE The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as
possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. (Refer to page 7.)
Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit to protect them from noise. (Refer to page 8.)
Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, immediately remove them.
Electromagnetic wave interference The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, install options among the capacitor type EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, Filterpack, and EMC filter to minimize the interference. ( Refer to Chapter 3 of the Instruction Manual (Applied).)
Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.
Noise filter (ferrite core) (FR-BSF01, FR-BLF) Install a noise filter (ferrite core) to reduce the electromagnetic noise generated from the inverter. Effective in the range from about 1MHz to 10MHz. A wire should be wound four turns at a maximum.
Motor
Earth (Ground)
Earth (Ground)
Devices connected to the output Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the output side of the inverter. When installing a molded case circuit breaker on the output side of the inverter, contact each manufacturer for selection of the molded case circuit breaker.
The regenerative braking capability of the inverter can be exhibited fully.
Power supply harmonics can be greatly suppressed.

Noise filter (ferrite core) * (FR-BSF01, FR-BLF)
AC power supply Use within the permissible power supply specifications of the inverter. To ensure safety, use a molded case circuit breaker, earth leakage circuit breaker or magnetic contactor to switch power ON/OFF.
Magnetic contactor (MC) Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shortened.
Molded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB), fuse The breaker must be selected carefully since an in-rush current flows in the inverter at power on.
Install a noise filter (ferrite core) to reduce the electromagnetic noise generated from the inverter. Effective in the range from about 1MHz to 10MHz. When more wires are passed through, a more effective result can be obtained. A wire should be wound four turns or more.
To prevent an electric shock, always earth (ground) the motor and inverter. For reduction of induction noise from the power line of the inverter, it is recommended to wire the earthing cable by returning it to the earth (ground) terminal of the inverter.

Peripheral devices
2.1 Peripheral devices
Check the inverter model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices.
Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
For the use in the United States or Canada, refer to page 50, and select an appropriate fuse or molded case circuit
breaker (MCCB).
Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is
used for emergency stop during motor driving, the electrical durability is 25 times.
If using an MC for emergency stop during motor driving, select an MC regarding the inverter input side current as JEM 1038-AC-3 class rated current. When
using an MC on the inverter output side for commercial-power supply operation switching using a general-purpose motor, select an MC regarding the rated
motor current as JEM 1038-AC-3 class rated current.
When connecting a single-phase 100V power input inverter to a power transformer (50kVA or more), install a AC reactor (FR-HAL) so that the performance
is more reliable. ( Refer to Chapter 3 of the Instruction Manual (Applied).)
The power factor may be slightly lower.
Single-phase 100V power input model is not compatible with DC reactor.

NOTE When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to
the inverter model and cable and reactor according to the motor output.
When the breaker on the inverter input side trips, check for the wiring fault (short circuit), damage to internal parts of
the inverter, etc. Identify the cause of the trip, then remove the cause and power ON the breaker.

Installation of the inverter and instructions
2.2 Installation of the inverter and instructions
(1) Installation of the inverter
Enclosure surface mounting
Remove the front cover and wiring cover to fix the inverter to the surface. (Remove the covers in the directions of the arrows.)
(2) Environment
Before installation, check that the environment meets the specifications on page 45.
Note When encasing multiple inverters, install them in parallel as a cooling
measure.
Install the inverter vertically.
For heat dissipation and maintenance, take at least the clearances
shown in the table below from the inverter to the other devices and to
the enclosure surface.
Take 5cm or more clearances for 5.5K or higher.
When using the inverters at the surrounding air temperature of 40C or less, the inverters can be installed without any clearance between
them (0cm clearance).
Note Install the inverter on a strong surface securely and vertically with bolts.
Leave enough clearances and take cooling measures.
Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.
Install the inverter on a nonflammable wall surface.
When designing or building an enclosure for the inverter, carefully consider influencing factors such as heat
generation of the contained devices and the operating environment.

2.3 Wiring 2.3.1 Terminal connection diagram
NOTE To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power cables. Also
separate the main circuit wire of the input side and the output side. After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.
The output of the single-phase power input model is three-phase 200V.
