	may result in minor or moderate injury or in property damage.

Alert Symbols in This Document

WARNING

Turn off the power supply and implement wiring correctly. Not doing so may result in a serious injury due to an electric shock.

Wiring work must be carried out only by qualified personnel. Not doing so may result in a serious injury due to an electric shock.

Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or fire.

(200-V class: type-D grounding, 400-V class: type-C grounding)

Do not remove the front cover during the power supply and 5 minutes after the power shutoff. Doing so may result in a serious injury due to an electric shock.

Do not operate the Digital Operator or switches with wet hands. Doing so may result in a serious injury due to an electric shock.

Inspection of the Inverter must be conducted after the power supply has been turned off. Not doing so may result in a serious injury due to an electric shock.

The main power supply is not necessarily shut off even if the emergency shutoff function is activated.

Do not change wiring, mode change switches (S7, S8), optional devices or replace cooling fans while the input power is being supplied.

Doing so may result in a serious injury due to an electric shock.

Safety Precautions

CAUTION

Do not connect resistors to the terminals (+1, P/+2, N/-) directly.

Doing so might result in a small-scale fire, heat generation or damage to the unit.

Install a stop motion device to ensure safety. Not doing so might result in a minor injury. (A holding brake is not a stop motion device designed to ensure safety.)

Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result in a moderate burn due to the heat generated in the braking resistor/regenerative braking unit. Configure a sequence that enables the Inverter power to turn off when unusual overheating is detected in the braking resistor/regenerative braking unit.

The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or other property. Place covers on the openings or take other precautions to make sure that no metal objects such as cutting bits or lead wire scraps go inside when installing and wiring.

Do not touch the Inverter fins, braking resistors and the motor, which become too hot during the power supply and for some time after the power shutoff. Doing so may result in a burn.

Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the Inverter capacity on the power supply side. Not doing so might result in damage to property due to the short circuit of the load.

Do not dismantle, repair or modify the product.

Doing so may result in an injury.

Transporting, Installation, and Wiring

•Do not drop or apply a strong impact on the product. Doing so may result in damaged parts or malfunction. •Do not hold by the front cover, but hold by the fins during transportation.

•Do not connect an AC power supply voltage to the control input/output terminals. Doing so may result in damage to the product.

•Be sure to tighten the screws on the terminal block securely. Wiring work must be done after installing the unit body.

•Do not connect any load other than a three-phase inductive motor to the U, V, and W output terminals. •Take sufficient shielding measures when using the product in the following locations. Not doing so may result in damage to the product.

Locations subject to static electricity or other forms of noise. Locations subject to strong magnetic fields.

Locations close to power lines.

Operation and Adjustment

•Be sure to confirm the permissible range of motors and machines before operation because the Inverter speed can be changed easily from low to high.

•Provide a separate holding brake if necessary.

Maintenance and Inspection

•Be sure to confirm safety before conducting maintenance, inspection or parts replacement.

Precautions for Correct Use

Installation

•Mount the product vertically on a wall or on a DIN track (optional) with the product's longer sides upright. The material of the wall has to be nonflammable such as a metal plate.

Main Circuit Power Supply

•Confirm that the rated input voltage of the Inverter is the same as AC power supply voltage.

Error Retry Function

•Do not come close to the machine when using the error retry function because the machine may abruptly start when stopped by an alarm.

•Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may abruptly start.

Non-Stop Function at Momentary Power Interruption

•Do not come close to the machine when selecting restart in the non-stop function at momentary power interruption selection (b050) because the machine may abruptly start after the power is turned on.

Operation Stop Command

•Provide a separate emergency stop switch because the STOP key on the Digital Operator is valid only when function settings are performed.

•When checking a signal during the power supply and the voltage is erroneously applied to the control input terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal.
