WARNING

 

Do not use a motor in a vertical application. If the driver protective 

function is activated, the motor will stop and the moving part may 

drop, thereby causing injury or damage to equipment.

 

Do not machine or modify the motor cable or connection cable. 

Doing so may result in fire or damage to equipment.

 

Do not forcibly bend, pull or pinch the cable. Doing so may result in 

fire or damage to equipment.

 

Do not touch the motor and driver when conducting the insulation 

resistance measurement or dielectric strength test.

 

Do not disassemble or modify the motor and gearhead. Doing so 

may result in injury or damage to equipment. Refer all such internal 

inspections and repairs to the branch or sales office from which you 

purchased the product.

 

Only qualified and educated personnel should be allowed to perform 

installation, connection, operation and inspection/troubleshooting 

of the product. Handling by unqualified and uneducated personnel 

may result in fire, injury or damage to equipment.

 

Use a motor, gearhead, and driver only in the specified combination. 

An incorrect combination may cause fire or damage to equipment.

 

Install the motor, gearhead and driver in an enclosure. Failure to do 

so may result in injury.

CAUTION

 

Do not use the motor and gearhead beyond the specifications. Doing 

so may result in fire, injury or damage to equipment.

 

Do not touch the motor and gearhead while operating or 

immediately after stopping. The surfaces of the motor and gearhead 

are hot, and it may cause a skin burn(s).

 

Do not leave anything around the motor that would obstruct 

ventilation. Doing so may result in damage to equipment.

 

Do not lift up the product by holding the output shaft of the motor 

or the gearhead, or the motor cable. Doing so may result in injury.

 

Do not touch the motor output shaft (end or pinion) with bare hands. 

Doing so may cause injury.

 

When assembling the motor (pinion shaft) with the gearhead, 

exercise caution not to pinch your fingers or other parts of your body 

between the motor and gearhead. Injury may result.

 

When installing the motor or gearhead in the equipment, exercise 

caution not to pinch your fingers or other parts of your body 

between the equipment and motor or gearhead. Injury may result.

 

Do not touch the rotating part (output shaft) while operating the 

motor. Doing so may cause injury.

 

Securely install the motor and gearhead to the mounting plate. 

Inappropriate installation may cause the motor and gearhead to 

detach and fall, resulting in injury or damage to equipment.

 

Provide a cover over the rotating part (output shaft) of the gearhead. 

Failure to do so may result in injury.

 

Securely install a load on the output shaft of the gearhead. 

Inappropriate installation may result in injury.

 

Be sure to ground the motor and driver to prevent them from being 

damaged by static electricity. Failure to do so may result in fire 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 the motor in 

operation, attach a warning label in a conspicuous
