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
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.
• 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.
• 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 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.
• 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 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 burn.
• 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, 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’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
• 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 +40 °C (+14 to +104 °F) (non-freezing)
−10 to +50 °C (+14 to +122 °F) for three-phase 200 V
• 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
• Round shaft type
Drill holes on the mounting plate and fix the motor on the plate
using screws, nuts, and washers (not supplied). Be careful there is no
gap between the motor installation surface and the bracket.

Note Do not insert the motor into the mounting hole at an
angle or force it in, as this may scratch the flange pilot
section and damage the motor.

• Pinion shaft type
Drill holes on the mounting plate and fix the motor and gearhead on
the plate using screws supplied with the gearhead. Be careful there is
no gap between the motor flange and the gearhead.
For details of installation, see the operating manual provided with
the gearhead, which is sold separately.

Note Use the gearhead with pinion shaft which is identical
with one of motor.
• Motor with cooling fan
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.
Connection and operation
Insulate all the wire connections, such as the connection between the
motor and the capacitor connection.
When the single-phase motor is run in only one direction, unused
lead wires should be insulated.
Ground the motor using a Protective Earth lead wire (green/yellow).
The direction of motor rotation is as viewed from the side of the
motor’s output shaft. The motor rotates in a clockwise (CW) and
counterclockwise (CCW) direction.
Note • Make sure that the motor case temperature does not
exceed 90 °C (194 °F) during operation of the motor.
Operation exceeding case temperature 90 °C
(194 °F) may significantly deteriorate the coils and
ball bearings of the motor and shorten the motor’s life
span. Motor case temperature can be measured by
fixing a thermometer on the motor surface. It can also
be measured using thermo tape or a thermocouple.
Thermal Class: 130 (B)
• To change rotation direction of the single-phase
motor, wait until the motor completely stops.
Otherwise its direction may not change or may take
much time to change.
 Rotating direction of the gearhead output
shaft
The rotating direction of the gearhead output shaft may be opposite
that of the motor shaft, depending on the gear ratio. For the rotating
direction of the output shaft of a specific gearhead used, refer to the
operating manual for the gearhead.
 Connection method to a terminal box
• Open the terminal box and connect wires.
• Use applicable cable ground and conduit for conduit opening.
• After connecting, close the terminal box with the terminal cover.
• Terminal cover screws tightening torque
Single-phase 25 W, 40 W/Three-phase: 0.3 N·m (2.6 lb-in)

Time rating
Motors have a continuous rating.
Locked rotor burnout protection
This motor is equipped with the feature listed below to prevent the
motor from burning out as a result of abnormal heating which may
be caused by misapplication.
• Thermal protection
“TP” is stamped on the motor nameplate. The motor has an “auto
reset” type thermal protector built into its motor coil. When the
motor reaches a predetermined temperature, the internal thermal
protector is activated and the motor is stopped.
Always turn the power off before performing inspections.
Thermal protector activation range
Power is turned off at 130±5 °C (266±9 °F)
Power is turned back on at 82±15 °C (180±27 °F)
