Safety precautions
The motor is designed for incorporation into industrial
equipment. Touching the motor during operation may result
in bodily injury or property damage, since the output shaft is
rotating and the surface remains very hot. To prevent injury
or damage to the motor, be sure the motor is handled and
operated only by qualified personnel familiar with operations
involving electronic equipment.

Handling the product without observing the instructions that
accompany a "Warning" symbol may result in death or serious
bodily injury.
standards.
y Do not use the motor in explosive or corrosive environments,
in the presence of flammable gases, near combustible
materials, or locations subjected to the splashing of oil or
other hazardous liquids. Doing so may result in fire, electric
shock or injury.
y Turn off the power before working on the product. Failure to
do so may result in electric shock.
y Provide a measure to retain the position of the movable
part of the equipment when the product is used in a vertical
application. The motor loses its holding torque when the
power is cut off. Without appropriate measures the movable
part will descend, resulting in injury or damage to the
equipment.
y Install the motor in the enclosure to avoid contact with the
hands, or provide sufficient earthing. Failure to do so may
result in electric shock.
y Connect the product correctly and securely according to the
wiring diagram. Failure to do so may result in fire or electric
shock.
y After connecting the cable, securely fix and tighten the
terminal box and cable clamp. Failure to do so may result in
fire or electric shock.
y Turn off the power in case of a power failure. Failure to do so
may result in injury or damage to the equipment when the
motor starts suddenly upon the recovery of power.
y Do not disassemble or modify the motor. This may cause
electric shock or injury.
Handling the product without observing the instructions that
accompany a "Caution" symbol may result in bodily injury or
property damage.
y Do not use the motor beyond its specifications. Doing so may
result in electric shock, injury or damage to the equipment.
y Do not touch the motor while the motor is conducting
current. Doing so may result in burns.
y Use a round terminal for connection with the protective earth
terminal. Failure to do so may result in fire or electric shock.
y Do not carry the motor by its output shaft. Doing so may
result in injury.
y Securely fix the motor to an appropriate metal plate. Failure
to do so may result in injury or damage to the equipment.
y Protect the rotating part of the motor (output shaft) with a
cover. Failure to do so may result in injury.
y Conduct the insulation resistance measurement or withstand
voltage test separately on the motor and the driver. Failure to
do so may result in damage to equipment.
y Immediately when trouble has occurred, stop running and
turn off the power. Failure to do so may result in fire, electric
shock or injury.

y To dispose of the motor, disassemble it into parts and
components as much as possible and dispose of individual
parts/components as industrial waste.
y Provide an emergency-stop device or emergency-stop circuit
external to the equipment so that the entire equipment will
operate safely in the event of a system failure or malfunction.
Failure to do so may result in injury.
Precautions for use
• Drive unit
Use a motor driver unit appropriate for the method of motor
connection.
• Connecting the motor
Use a multi-core cable of AWG26 to 16 (0.14 to 1.25 mm
[7 to 13 mm (0.28 to 0.51 in.) in outer diameter] for motor
connection. Motor cable (with protective earth conductor) is
available as an option (sold separately). For details, contact your
nearest Oriental Motor office.
Strip away 40 to 50 mm (1.57 to 1.97 in.) of sheath from the end
of the cable. Stripping the cable sheath by more than 50 mm
(1.97 in.) will reduce the sealing effect of the cable clamp.
• Cable clamp
"Cable clamp" is a section through which a cable passes. The
cable clamp conforms to the IP65 specification and consists of
the cap, gasket and receptacle. To ensure watertightness at the
cable clamp, tighten the cap after confirming that the cover of
the connection cable is securely sealed by the gasket.
• Motor case temperature
The motor is designed to the class B insulation specification.
When operating the motor, keep the motor case temperature to
100 °C (212 °F) or below. Operating the motor at temperatures
above 100 °C (212 °F) will shorten the life of the motor coil and
ball bearing. [The maximum temperature is 75 °C (167 °F) if the
equipment is to receive UL/CSA certification, because the motor
must conform to the class A insulation requirement.]
Installation
„ Installation requirements
The motor is designed to be a built-in component. It must be
used in an environment conforming to overvoltage category II,
pollution degree of class 3 and protection against electric shock
of class I equipment.
Degree of protection: IP65 (Excluding the gap between the
shaft and the flange)
Install the motor in a well-ventilated location that provides
easy access for inspection. The locaton must also satisfy the
following conditions:
y Inside an enclosure that is installed indoors (provide vent
holes)
y Operating ambient temperature: −10 to +50 °C (+14 to
+122 °F) (non-freezing)
y Operating ambient humidity: 85% or less (non-condensing)
y Area that is free of explosive atmosphere or toxic gas (such as
sulfuric gas) or liquid
y Area not exposed to direct sun
y Area free of excessive salt
y Area not subject to continuous vibration or excessive shocks
y Area free of excessive electromagnetic noise (from welders,
power machinery, etc.)
y Area free of radioactive materials, magnetic fields or vacuum
