WARNING
•
Do not use the product in explosive or corrosive environments, in the presence of ammable gases, locations subjected to splashing
water, or near combustibles. Doing so may result in re or injury.
•
Do not forcibly bend, pull, or pinch the cable. Doing so may result in re.
•
Do not use in vertical drive such as elevating equipment. When the driver protective function is activated, the motor will stop
operating. The moving part may fall, 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 oce from which you purchased the product.
•
Only qualied and educated personnel should be allowed to perform installation, connection, operation and inspection/
troubleshooting of the product. Handling by unqualied 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 specied 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.
•
If the motor is operated by turning on and o the power supply, 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.
CAUTION
•
Do not use the motor, gearhead, and driver beyond the specications. 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 lift up the motor by holding the output shaft of the motor or the gearhead, or the motor cable. Doing so may cause the
product to fall, leading to injury.
•
Keep the area around the motor and driver free of combustible materials. Failure to do so may result in re or a skin burn(s).
•
Do not leave anything around the motor and driver that would obstruct ventilation. Doing so may result in damage to equipment.
•
Do not shut o the negative side of the power supply. Also, make sure that the wiring for the power supply does not disconnect. This
may result in damage to equipment.
•
Do not touch the rotating part (output shaft) while operating the motor. Doing so may cause injury.
•
Pay enough attention to safe operation when starting and stopping the motor by switching ON-OFF of the power supply. Failure to
do so may result in 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 specied 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 result in 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.
•
The motor surface temperature may exceed 70 °C (158 °F) even under normal operating conditions. If the operator is
allowed to approach the 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).
