Safety precautions

The precautions described below are intended to ensure the safe and correct use of the prod-
uct, and to prevent the customer or others from exposure to the risk of injury.
Read the body of the text based on a sufficient understanding of its importance.
Failure to observe the warnings contained herein may result in a situation leading to serious
injury or death.
G 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.
G Qualified personnel are required for the installation, connection, operation and inspection of
this product. Failure to do so may result in fire, electric shock or injury.
G Be sure to turn off the power before installing, connecting or inspecting this product. Failure
to do so may result in electric shock.
G Install the motor in the enclosure to avoid contact with the hands, or provide sufficient ground-
ing. Failure to do so may result in electric shock or injury.
G Connect this product securely and accurately, according to the connection diagrams. Failure
to do so may result in fire or electric shock.
G Be sure to insulate the connection terminals of the capacitor and external resistor. Failure to
do so may result in electric shock.
G Do not forcibly bend, pull or pinch the motor cable. Doing so may result in fire or electric
shock.
G In case of power failure, be sure to turn off the power. Failure to do so may cause the motor
to start suddenly when the power is restored, and could result in injury or damage to the
equipment.
G If this product is used in an elevator application, be sure to provide a measure for the posi-
tion retention of moving parts. The motor loses its retentiveness when the power is turned off.
Failure to provide such a measure may cause the moving parts to fall off, resulting in injury
or damage to the equipment.
G Do not touch the connection terminals of the motor or capacitor immediately after the power
is turned off (for a period of 30 seconds). The residual voltage may cause electric shock.
G Do not disassemble or modify the motor. Doing so may result in electric shock, injury or dam-
age to the equipment.
Failure to observe the following precautions may result in injury or property damage.
G Do not use the motor beyond the specified values. Doing so may result in electric shock,
injury or damage to the equipment.
G Do not hold the motor shaft or motor cable. Doing so may result in injury.
G Be sure to secure the motor onto the metal plate. Failure to do so may result in injury or dam-
age to the equipment.
G Be sure to cover the rotating portion (motor shaft) of the motor. Failure to do so may result in
injury.
G If any abnormality is detected, turn the power off immediately. Failure to do so may result in
fire, electric shock or injury.
G Do not touch the motor or external resistor during operation or immediately after the equip-
ment is stopped, since the surfaces of the motor and external resistor will be extremely hot.
Failure to do so may result in a burn.
G The surface temperature of the motor may exceed 70°C (158°F), even during normal oper-
ation. Be sure to attach a warning label, as shown in the figure, in a clearly visible location if
it is possible for the operator to access the motor during operation.
Failure to do so may result in a burn.
G Dispose of the motor as industrial waste.
