 Precautions for installation

 Precautions for Running and Test Running
DANGER
Risk of electric shock or fire!
• While power is supplied to the inverter, do not touch any internal part or the terminal of the inverter. Also do not check signals orconnect or disconnect any wire or connector.
• While power is supplied to the inverter, do not touch any internal part of the inverter. Also do not insert a bar in it.

Risk of electric shock!
• 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. Do not touch the internal PCB, terminal block or connector
while power is being supplied to the inverter or voltage remains inside.
• Do not operate switches in the inverter or on the board with wet hands.

Risk of injury or fire!
While power is supplied to the inverter, do not touch the terminal of the inverter, even if it has stopped.

Risk of injury and damage to machine!
Do not select the retry mode for controlling an elevating or traveling device because free-running status occurs in retry mode.

Risk of injury!
If the retry mode has been selected, the inverter will restart suddenly after a break upon detection of an error. Stay away from themachine 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.)• The STOP/RESET key on the operator keypad can be enabled/disabled using the "STOP-key enable [AA-13]" and it is effective
only when there is no connection abnormality between the keypad and the main unit. Prepare an emergency stop switch separately.
• 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 system configuration that disables the inverter
from restarting after power recovery.
• 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 (by terminal, key operation or communication). Before resetting the alarm status, make sure thatno operation command has been input.
• When an unexpected event occurs, do not touch the inverter or cable.
• Make sure to understand and check the functions the inverter provides to ensure safety. Be careful that operation commands orresetting operation do not cause an unexpected restart.
• When an error (alarm) occurs, before moving to the next operation (resetting the alarm status or reapplying the power), makesure that no operation command has been input. If the inverter has received an operation command, it will restart automatically.

WARNING
Risk of injury and damage to machine!
The inverter allows you to easily control the speed of the motor or machine operations. Before operating the inverter, confirm thecapacity and ratings of the motor or machine controlled by the inverter.

Risk of burn injury!
Do not touch the heat sink, which heats up during the inverter operation.

Risk of injury!
Install an external brake system if needed.

 Precautions for Maintenance/Daily Inspection

WARNINGDANGER

Risk of Fire!

Risk of electric shock!

• Do not place flammable materials near the installed inverter.
• Prevent foreign matter (e.g., cut pieces of wire, sputtering welding materials, iron chips, wire, and dust) from entering the inverter.
• Install the inverter on a non-flammable surface, e.g., metal.
Install the inverter in a well-ventilated indoor site not exposed to direct sunlight. Avoid places where the inverter is exposed tohigh temperature, high humidity, condensation, dust, explosive gases, corrosive gases, flammable gases, grinding fluid mist,hydrogen sulfide or salt water.

Entrust only a designated person for maintenance, inspection, and the replacement of parts.
(Be sure to remove wristwatches and metal accessories, e.g., bracelets, before maintenance and inspection work and to use insulated tools for the work.)
Before inspecting the inverter, be sure to turn off the power supply and more than 10 minutes. (Confirm that the Charge lamp on
the inverter is off and the DC voltage between terminals [P/+] and [N/-] is 45 VDC or less.)

Risk of Injury!
Do not install or operate the inverter if it is damaged or parts are missing.

Risk of injury due to the inverter falling!
When carrying the inverter, do not hold its parts to cover terminals or connectors.
• Install the inverter on a structure able to bear the weight specified in the User's Guide.
• Install the inverter on a vertical wall that is free of vibrations.

Risk of failure of the inverter!
• The inverter is precision equipment. Do not allow it to fall or be subject to high impacts.
• Also do not step on it or place a heavy load on it.
• Avoid places where static electricity discharges often occur (for example, on a rug) for the operation of the product.
In order to discharge static electricity from your body, touch a safe metal surface first before starting the operation.

 Precautions for Wiring

 Precautions for Disposal
DANGER
Risk of injury and explosion!
For disposal of the inverter, outsource to a qualified industrial waste disposal contractor. Disposing of the inverter on your own may
result in an explosion of the capacitor or produce poisonous gas.
A qualified industrial waste disposal contractor includes industrial waste collector/ transporter and industrial waste disposal operator. Follow the laws and regulations of each country for disposing of the inverter.

 Other Cautions
DANGER
Risk of electric shock, fire and injury!
Never modify the inverter.

DANGERCAUTION

Risk of an electric shock and/or fire!

Risk of significantly shortening the life cycle of the product!

• Be sure to ground the inverter.
• Entrust wiring work to a qualified electrician.
• Before the wiring work be sure to turn off the power supply and wait for more than 10 minutes.
(Confirm that the voltage between terminals [P/+] and [N/-] is 45 VDC or less.)

If wood materials for packaging need to be sterilized and disinfected, be sure to use a means other than the wood fumigation
method. If the product is included in the fumigation treatment, electronic parts could receive critical damage from the emitted
gases or vapors. Especially, halogen disinfectants (including fluorine, chlorine, bromine and iodine) can cause corrosion in thecapacitor.

Risk of failure of the inverter!

Make sure that the voltage and frequency of AC power supply match the rated voltage (AC input voltage) and frequency of yourinverter.

Risk of electric shock and injury!
• Before operating the slide switch in the inverter, be sure to turn off the power supply.
• Since the inverter supports two modes of cooling-fan operation, the inverter power is not always off, even when the cooling fan
is stopped.
• Before operating the switch, be sure to turn off the power supply and wait for more than 10 minutes.
(Confirm that the DC voltage between terminals [P/+] and [N/-] is 45Vdc or less.)• Prevent the distribution cable from being compressed or getting caught to avoid damage to the cable.

Risk of fire!
• Do not use a single-phase input for 3 phase models.
• Do not connect a resistor directly to between [P1/+1] and [N/-] or [P/+] and [N/-].
• Do not use the magnetic contactor installed on the primary and secondary sides of the inverter to stop its operation.
• Tighten the screws and bolts with the specified torque.
• No screws or bolts must be left loose.
• Connect an earth-leakage breaker to the power input circuit.
• Use only the power cables, earth-leakage breaker, and magnetic contactors that have the specified capacity (ratings).

Risk of damage to the inverter and burnout of the motor!
Do not operate the inverter when an output phase is lost (output phase loss).
