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.
• 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 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.
• 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 or lead wires. Doing so may
result in fire and electric shock.
• Turn off the power in the event of a power failure, or the motor will
suddenly start when the power is restored and may cause injury or damage
to equipment.
• Do not disassemble or modify the motor. This may cause electric shock or
injury.
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 skin burn(s).
• Do not hold the motor output shaft and cable. This may cause injury.
• Keep the area around the motor free of combustible materials in order to
prevent fire or a skin burn(s).
• To prevent the risk of damage to equipment, leave nothing around the
motor that would obstruct ventilation.
• To prevent bodily injury, do not touch the rotating parts (output shaft) of
the motor during operation.
• When an abnormality is noted, turn off the power immediately, or fire,
electric shock or injury may occur.
• The motor’s surface temperature may exceed 70 °C, even
under normal operating conditions. If a motor is accessible
during operation, post the warning label shown in the figure
in a conspicuous position to prevent the risk of skin burn(s). Warning
label
• To dispose of the motor, disassemble it into parts and components as much
