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.
Handling the product without observing the instructions that
WARNING
accompany a "Warning" symbol may result in serious injury or
death.
Handling the product without observing the instructions that
CAUTION
accompany a "Caution" symbol may result in injury or property
damage.
The items under this heading contain important handling
Note
instructions that the user should observe to ensure safe use of
the product.
• 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.
• 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 connection 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.
• 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 or motor lead wires. 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.
• The motor does not have a built-in overheat protection device. Provide a protection
device externally.
• To prevent bodily injury, do not touch the rotating parts (output shaft, cooling fan) 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 surface temperature may exceed 70 °C (158 °F) even under
normal operating conditions. If the operator is allowed to approach
the running motor, attach a warning label as shown in the figure in a
conspicuous position. Failure to do so may result in a skin burn(s).
• Dispose the product correctly in accordance with laws and regulations, or instructions of
local governments.

Installation
„ Location for installation
„
The motor is designed and manufactured for installation in equipment.
Install it in a well-ventilated location that provides easy access for inspection.
The location must also satisfy the following conditions:
• Inside an enclosure that is installed indoors (provide vent holes)
• Operating ambient temperature −10 to +50 °C (+14 to +122 °F) (non-freezing)
• Operating ambient humidity 85%, maximum (non-condensing)
• Area that is free from an explosive atmosphere or toxic gas (such as sulfuric gas) or liquid
• Area not exposed to direct sun
• Area free of excessive amount dust, iron particles or the like
• Area not subject to splashing water (storms, water droplets), oil (oil droplets) or other
liquids
• Area free of excessive salt
• Area not subject to continuous vibration or excessive shocks
• Area free of excessive electromagnetic noise (from welders, power machinery, etc.)
• Area free of radioactive materials, magnetic fields or vacuum
• 1000 m (3300 ft.) or less above sea level
„ How to install the motor
„
When installing a motor with cooling fan onto a device, leave 10 mm (0.39 in.) or
more behind the fan cover or open a ventilation hole so that the cooling inlet on the
back of the motor cover is not blocked.
z Pinion shaft type
Assembling
Keep the pilot sections of the motor and gearhead
in parallel, and assemble the gearhead with
the motor while slowly rotating it clockwise/
counterclockwise. At this time, note so that the
pinion of the motor output shaft does not hit
the side panel or gears of the gearhead strongly.
Assemble the gearhead to the motor in a condition
where the motor output shaft is in an upward
direction.
Installing
Drill holes on the mounting plate and fix the
motor and gearhead on the plate using screws
supplied with the gearhead. Do not leave a gap
between the motor and mounting plate.
Refer to the Oriental Motor Website for the
screw specifications.
• Use the gearhead with pinion shaft which is identical with one of motor.
Note
• Do not forcibly assemble the motor and gearhead. Also, prevent metal
objects or foreign substances from entering in the gearhead. The pinion
of the motor output shaft or gear may be damaged, resulting in noise
or shorter service life.
