 RoHS Directive
The products do not contain the substances exceeding the restriction values of
RoHS Directive (2011/65/EU).
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.
 Do not use the product in explosive or corrosive environments, in the presence
of ammable gases, or near combustibles. Doing so may result in re, electric
shock or injury.
 Only qualied and educated personnel should be allowed to perform
installation, connection, operation and inspection/troubleshooting of the
product. Handling by unqualied and uneducated personnel may result in re,
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 І 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 specied range. Failure to do so may
result in re or electric shock.
 Securely connect the cables in accordance with the connection examples.
Failure to do so may result in re or electric shock.
 Do not forcibly bend, pull or pinch the lead wires. Doing so may result in re
and electric shock.
 Insulate the connection terminals of the supplied capacitor using the supplied
capacitor cap. Failure to do so may result in electric shock.
 Turn off the power in the event of a power failure. Or the motor may 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
Handling the product without observing the instructions that accompany a
"Caution" symbol may result in injury or property damage.
 Do not use the motor beyond its specications. Doing so may result in electric
shock, injury or damage to equipment.
 Do not touch the motor during operation or immediately after stopping. The
surface is hot and may cause a skin burn(s).
 Do not lift the motor by holding the motor output shaft or motor lead wires.
Doing so may result in injury.
 Keep the area around the motor free of combustible materials. Failure to do so
may result in re or a skin burn(s).
 Do not leave anything around the motor that would obstruct ventilation. Doing so
may result in damage to equipment.
 Do not touch the rotating part (output shaft) while operating the motor. Doing
so may result in injury.
 When an abnormality is noted, turn off the power immediately. Failure to do so
may result in re, electrical shock or injury.
 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 gure in a conspicuous position.
Failure to do so may result in a skin burn(s). Warining label
 Dispose the product correctly in accordance with laws and regulations, or
instructions of local governments.

 When using the supplied hexagonal socket head screw set
Note  When using the gearhead ange to mount the geared motor to
equipment, proper alignment between the hollow shaft inside
dimension and the load shaft is necessary. Keep the alignment
tolerance within 0.02 mm (0.0008 in.). Insufcient alignment may
result in damage to the gearhead internal bearings.
 Do not disassemble the gearhead from the motor.
z 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.
 Installing a load to the hollow shaft type
Mounting method of the load varies depending on the load shaft conditions. See
the following gures. The hollow output shaft inside dimension is processed to
a tolerance of H8, and incorporates a key slot for load shaft attachment. A load
shaft tolerance of h7 is recommended. Apply grease on the surface of the load
shaft and inner walls of the hollow output shaft to prevent seizure.

 Installing a load to the solid shaft type
The shaft of the gearhead has been machined to an outer diameter tolerance
of h7 and is provided with a key slot for connecting the transmission parts.
When connecting the transmission parts, ensure that the shaft and parts have a
clearance t, and always x the parallel key to the output shaft with a screw to
prevent the parts from rattling or spinning. With solid shaft type, use this screw
hole as an auxiliary means for preventing the transmission parts from coming off.

 Capacitor connection
The capacitor internal wiring as follows: Capacitor terminals are
internallyelectrically connection in twos; A-B and C-D for easy connection.
For easy to install terminals use 187 series FASTON terminals (TE Connectivity).

Note For lead wire connection, use one lead wire for each individual
terminal.
Operation
When the power is turned on, the motor rotates.
Note  Make sure that the motor case temperature does not exceed 90 °C
(194 °F) when operating the motor. Operation exceeding case temperature
90 °C (194 °F) may signicantly deteriorate the coils and ball bearings of
the motor and shorten the motor's life span. Motor case temperature can
be measured by xing a thermometer on the motor surface. It can also be
measured using thermo tape or a thermocouple.
 When an ambient temperature is low, since the load torque may increase
by the viscosity increment of the oil seal or grease, the motor starting may
take a long time or the motor rotation speed may fall.
However, if the operation is continued for a while, the oil seal or grease
will be warmed up, and the motor can be driven at the normal rotation
speed.
Time rating
Continuous operation is possible (continuous rating).
Overheat protection for locked condition
The motor is equipped a function of overheat protection for when the motor
output shaft is locked.
 Thermally protected motors
"TP" is marked on the motor nameplate. This motor contains a built-in automatic
return type thermal protector in the motor windings. If the motor internal
temperature exceeds the specied value, the thermal protector is activated and
the motor is stopped.
Always turn the power off before performing inspections.
Operating temperature of thermal protector
Open (motor standstill)...............130±5 °C (266±9 °F)
Close (resuming operation)........85±20 °C (185±36 °F)
Troubleshooting
