•
Do not forcibly bend, pull, or pinch the cable. Doing so may result in re.
•
Do not use in a vertical application. When the driver protective function is activated, the motor will stop operating. The
moving parts may drop, leading to injury or damage to equipment.
•
Do not disassemble or modify the motor, gearhead or driver. Doing so may cause injury. Refer all such internal inspections
and repairs to the branch or sales oce from which you purchased the product.
•
Only qualied and educated personnel should be allowed to perform installation, connection, operation and inspection/
troubleshooting of the product. Handling by unqualied and uneducated personnel may result in re, injury or damage to
equipment.
•
If the driver protective function was activated, remove the cause before canceling the alarm. Continuing the operation
without removing the cause of the problem may cause malfunction of the motor, leading to injury or damage to equipment.
•
Install the motor, gearhead and driver in an enclosure. Failure to do so may result in injury.
•
Always keep the power supply voltage of the driver within the specied range. Failure to do so may result in re.
•
Connect the cables securely according to the wiring example. Failure to do so may result in re.
•
For the driver power supply, use a DC power supply with reinforced insulation on its primary and secondary sides. Failure to
do so may result in electric shock.
•
Turn o the driver power in the event of a power failure. Otherwise, the motor may suddenly start when the power is restored,
causing injury or damage to equipment.
•
Do not use the product in conditions exceeding the motor, gearhead or driver specications. Doing so may result in injury or
damage to equipment.
•
Do not touch the motor and driver during operation or immediately after stopping. The surface is hot, and this may cause a
skin burn(s).
•
Do not move the product by holding the output shaft of the motor or the gearhead, or the motor cable. Doing so may cause
the product to drop, leading to injury.

Do not leave anything around the motor and driver that would obstruct ventilation. Doing so may result in damage to
equipment.
•
Do not touch the rotating part (output shaft) while operating the motor. Doing so may cause injury.
•
Do not start or stop the motor operation by switching on or o the power supply. Use the operation input signals of the driver
to operate the motor. Starting and stopping by power-on/o may cause injury or damage to equipment.
•
Provide a cover over the rotating part (output shaft) of the motor and gearhead. Failure to do so may result in injury.
•
Use a motor and driver only in the specied combination. An incorrect combination may cause a re.
•
Provide an emergency stop device or emergency stop circuit external to the equipment so that the entire equipment will
operate safely in the event of a system failure or malfunction. Failure to do so may cause injury.
•
Immediately when trouble has occurred, stop operation and turn o the driver power. Failure to do so may result in re,
electrical shock or injury.
•
Before turning on the power to the driver, make sure to turn all input signals of the driver to OFF. Otherwise, the motor may
suddenly start when the power is on, leading to injury or damage to equipment.
•
The motor surface temperature may exceed 70 °C (158 °F) even under normal operating conditions. If the
operator is allowed to approach a motor in operation, attach a warning label in a conspicuous position as
shown in the gure. Failure to do so may result in a skin burn(s).
