Note The items under this heading contain important handling instructions that the user should observe to ensure safe use of the product. Description of graphic symbols :Indicates "prohibited" actions that must not be performed. :Indicates "compulsory" actions that must be performed. WARNING • Do not use the product in explosive or corrosive environments, in the presence of flammable gases, locations subjected to splashing water, or near combustibles. Doing so may result in fire, electric shock or injury. • Do not transport, install the product, perform connections or inspections when the power is on. Always turn the power off before carrying out these operations. Failure to do so may result in electric shock or equipment damage. • Do not use the electromagnetic brake of the motor as a safety brake. Take safety measures other than the electromagnetic brake. Failure to do so may result in injury or damage to equipment. • Use an electromagnetic brake motor in an application of vertical drive such as elevating equipment. If a motor without an electromagnetic brake is used, the moving part may drop. This may result in injury or damage to equipment. • Do not machine or modify the connection cable. Doing so may result in electric shock or fire. • Do not forcibly bend, pull or pinch the cables. Doing so may result in fire and electric shock. • Do not touch the motor or speed controller when conducting insulation resistance measurement or dielectric strength test. Accidental contact may result in electric shock. • Do not disassemble or modify the motor and gearhead. This may cause electric shock or injury. • 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, electric shock, injury or equipment damage. • The motor is Class І equipment. When installing the motor, ground the Protective Earth Terminal of the motor. Failure to do so may result in electric shock. • Keep the input power voltage within the specified range. Failure to do so may result in fire or electric shock. WARNING • Use a motor, gearhead and speed controller only in the specified combination. An incorrect combination may cause in fire, electric shock or equipment damage. • Always turn off the power before performing maintenance/inspection. Failure to do so may result in electric shock. CAUTION • Do not use the motor, gearhead beyond its specifications. Doing so may result in electric shock, injury or damage to equipment. • Do not touch the motor, gearhead during operation or immediately after stopping. The surface is hot and may cause a skin burn(s). • Keep the area around the motor free of combustible materials. Failure to do so may result in fire or 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 carry the product by holding the motor, gearhead output shaft or any of the cables. Doing so may result in injury. • Do not touch the motor output shaft (tip or pinion) with bare hands. Doing so may result in 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, 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 result in injury. • When an abnormality is noted, turn off the power immediately. Failure to do so may result in fire, electrical shock or injury. • Securely install the motor, gearhead to their respective mounting plates. Inappropriate installation may cause the motor, gearhead to detach and fall, resulting in injury or equipment damage. • Provide a cover on the rotating part (output shaft). Failure to do so may result in injury. • Securely install the load on the motor and gearhead output shaft. Inappropriate installation may result in injury. • Be sure to ground the motor and speed controller 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 a running motor, attach a warning label as shown in the figure in a conspicuous position. Failure to do so may result in skin burn(s). Warning label Precautions for use This section covers limitations and requirements the user should consider when using the product. z Be sure to match the output power and power supply voltage when combining a motor and speed controller z Connecting the motor and speed controller Use a connection cable (sold separately) when extending the wiring distance between the motor and the speed controller. z Use an electromagnetic brake motor in an application of vertical drive such as elevating equipment When the motor is used in an application of vertical drive such as elevating equipment (lifting and lowering device), use an electromagnetic brake motor so that the load can be held in position. z Caution when using under low temperature environment When an ambient temperature is low, since the load torque may increase by the viscosity increment of the oil seal or grease, the motor starting may take a long time or the motor rotation speed may fall. However, if the operation is continued for a while, the oil seal or grease will be warmed up, and the motor can be driven at the normal rotation speed.
