1. Safety precautions
The precautions described below are intended to prevent danger or injury to the user and other personnel through safe, correct use of the product.
Use the product only after carefully reading and fully understanding these instructions.
WARNING
Handling the product without observing the instructions that accompany a “WARNING” symbol may result in serious injury or death.
CAUTION
Handling the product without observing the instructions that accompany a “CAUTION” symbol may result in injury or property damage.
Note
The items under this heading contain important handling instructions that the user should observe to ensure safe use of the product.
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.
• Assign qualified personnel the task of installing, wiring, operating/controlling, inspecting and troubleshooting the product. Failure to do 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.
• Do not use the motor’s built-in electromagnetic brake mechanism for stopping or for safety purposes. Using it for purposes other than holding the
moving parts and motor in position may cause injury or damage to equipment.
• Turn off the power in the event the overheat protection device (thermal protector) is triggered. Failure to do so may result in injury or damage to
equipment, since the motor will start abruptly when the overheat protection device (thermal protector) is automatically reset.
• The load-holding force will be lost if the motor’s overheat protection device (thermal protector) is activated. Provide a safety measure by using a
separate circuit interrupter to engage the brake. Failure to do so may result in injury or damage to equipment.
• The motor is Class
Ⅰ
equipment.
Install the motor so as to avoid contact with hands, or ground it to prevent the risk of electric shock.
• Install the motor in an enclosure in order to prevent electric shock or injury.
• Keep the input-power voltage within the specification to avoid fire and electric shock.
• Connect the cables securely according to the wiring diagram in order to prevent fire and electric shock.
• Do not forcibly bend, pull or pinch the cable. Doing so may fire and electric shock.
• Be sure to insulate the connection terminal of the capacitor. Failure to do so may result in electric shock.
• Turn off the power in the event of a power failure, or the motor may suddenly start when the power is restored and may cause injury or damage to
equipment.
• Do not touch the connection terminals of the capacitor immediately after the power is turned off (for a period of 30 seconds). The residual voltage
may cause electric shock.
• Do not disassemble or modify the motor. This may cause electric shock or injury. Refer all such internal inspections and repairs to the branch or
sales office from which you purchased the product.
CAUTION
• Do not use the motor beyond its specifications, or electric shock, injury or damage to equipment may result.
• Do not touch the motor during operation or immediately after stopping. The surface is hot and may cause a burn.
• Do not hold the motor output shaft or motor cable. This may cause injury.
• Keep the area around the motor free of combustible materials in order to prevent fire or a burn.
• To prevent the risk of damage to equipment, leave nothing around the motor that would obstruct ventilation.
• Provide a cover over the rotating parts (output shaft) of the motor to prevent injury.
• When an abnormality is noted, stop the operation immediately, or fire, electric shock or injury may occur.
• The motor’s surface temperature may exceed 70°C, even under normal operating onditions. If a motor is accessible
during operation, post a warning label shown in the figure in a conspicuous position to prevent the risk of burns.
• Dispose the product correctly in accordance with laws and regulations, or instructions of local governments.
