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.
• 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.
• To prevent the risk of electric shock, use the motor for class I equipment
only.
Motore zur Verwendung in Geräten der Schutzklasse I.
• Install the motor in an enclosure in order to prevent electric shock or
injury.
• Install the motor so as to avoid contact with hands, or ground it to prevent
the risk of electric shock.

mit dem geerdeten Gehäuse des Gerätes zu verbinden.
• 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 lead wires. Doing so may result in
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 will
suddenly start when the power is restored and may cause injury or damage
to equipment.
• Do not touch the connection terminal 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.
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. 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.
