3. Installation
Installation conditions
Install the motor and capacitor according to the following conditions:
Use under other than these conditions may damage the product.
- Indoor (the product is designed and manufactured to be mounted
in a machine)
- Ambient temperature: -10C(14F) to +40C(104F) (no freezing)
( -10C(14F) +50C(122F) for 100V/200V )
- Ambient humidity: Less than 85% (no condensation)
- No explosive, flammable, and/or corrosive gas.
- Not exposed to direct sunlight.
- Not exposed to dirt.
- Not exposed to moisture or oil.
- Well ventilated and allows heat radiation.
- Does not receive continuous vibration or excessive shock.
- 1,000 meters or less above sea level.
- Overvoltage category II , Pollution degree 2, Class I equipment
(For EN/IEC Standards)
When the machinery to which the motor is mounted requires
overvoltage category III and pollution degree 3 specifications,
install the motor in a cabinet that comply with IP54 and connect
to power supply via an isolation transformer.
3. 1 Installation of the motor
Installation method vary according to motor output shaft style.

(not provided)
Note: Do not force the motor into the pilot hole of the
mounting bracket.If the holes don't match
correctly the motor may be damaged.
Drill holes on the installation bracket and mount the motor on the bracket
using screws, nuts, and washers (screws for attaching are not supplied).
Be careful no to leave a gap between the motor installation face and the
bracket.

Screws provided
with gearhead
Drill holes on the installation bracket and fix the motor and gear head on the
bracket using screws delivered with the gear head. Be careful there is no gap
between the motor flange surface and the gear head. For details of installation,
see the instruction manual of the separately sold gear head.
Note
: Use the gear head with pinion shaft which is identical with one of the motor.
3) Motor with cooling fan
To install a motor with an integrated cooling fan , provide 10 mm or more space at back of the fan cover to prevent blockage of cooling fan air
inlet at the end of the motor, or provide a ventilation hole.
3. 2
Mounting the capacitor (For only single-phase motors)
Before mounting the provided capacitor,check that the capacitors capacitance matches that stated on the motors
name plate .
Use M4 screws to mount the capacitor (screws not provided).
Note -Do not let the screw fastening torque exceed 1 Nm (10kgfcm) to prevent damage to the mounting feet.
-Mount capacitor at least 10cm(3.94inches) away from the motor. If it is located closer, the life of the
capacitor will be shortened.

Dimensions in millimeters(inches).
4. Connection and Operation
- Connect the motor according to the wiring diagram shown below.
- Insulate all the wire connections, such as the connection between the motor and the capacitor connection.
Capacitor cap are available to insulate capacitor connection.

Note 1 : Insulation class of this motor is B.
Make sure that the motor case temperature does not exceed 90C(194F) during operation of the motor. Operation exceeding case
temperature 90C(194F) may significantly deteriorate the coils and ball bearings of the motor and shorten motors 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.
Note 2 : To change rotation direction of the induction motor, wait until the motor completely stops. Otherwise its direction may not change or
may take much time to change.
Note 3 : Single-phase motors use a capacitor and keep it connected even after rotation of the motor has started.
Capacitor Connection (For only single-phase motors)
C
A
AMP 187 series
D
The capacitor internal wiring is as follows:
Capacitor terminals are internally electrically connected in twos;AB and CD for easy connection.
For easy to install terminals use 187 series AMP FASTON Terminals.
For lead wire connection, use one lead wire for each individual terminal.
5. Time Rating
Induction motors have a continuous rating.
Reversible motors have a 30 minutes rating. " 30min" is indicated on the nameplate.
6. Locked rotor burnout protection
This motor is equipped with one of two methods to prevent burning the motor as a result of abnormal heating .
Thermal protection (TP TP211is stamped on the motor name plate)
When the motor reaches a predetermined temperature, the internal thermal protector is activated and the motor is stopped.
In this stage,the electromagnetic brake is left released so that the motor does not keep hold of the load.Adopt another safety measure.
With the automatic resume feature, the motor automatically begins operating again as soon as the motor temperature falls to a temp.
Always turn the power off before performing inspections.
Thermal protector activation range:
Power is turned off at 130C(266F) 5C(9F)
Power is turned back on at 82C(180F)15C(27F)
Impedance protection (ZP is stamped on the motor name plate)
When the motor goes into locked rotor condition due to a malfunction, coil impedance rises, suppressing input to the motor and
protecting the motor coil from burnout.
7. Troubleshooting
When the motor does not operate normally, check by referring to the table below.
If the motor does not operate normally even after checking, contact your nearest ORIENTAL MOTOR office for further information.
Phenomena
Motor does not rotate or rotates slowly.
Motor sometimes rotates and stops.
Motor rotates in reverse direction.
Motor temperature abnormally high
(Motor case temperature exceeds
90C(194F))
Noisy operation
Check items
1) Is supplied voltage appropriate?
2) Is the power source securely connected?
3) Is the load on the motor too much?
4) Is there a faulty contact on terminal blocks or crimped terminals if the cable is extended these
methods?
5) For a single-phase motor is the capacitor properly connected as per the wiring diagram
shown in page 3.
1) Is the power source securely connected?
2) Is there a faulty contact on terminal blocks or crimping terminals?
3) For a single-phase motor is the capacitor properly connected as per the wiring diagram
shown in page 3.
1) Is the motor connected differently than the wiring diagram shown in this
manual. Check wiring by referring to the wiring diagram in page 3.
2) In some gear heads, rotation direction of the gear head output shaft may differ from rotation
direction of the motor. See the instruction manual of the gear head.
3) For a single-phase motor is the capacitor properly connected as per the wiring diagram
shown in page 3.
4) Is your understanding of rotation direction different than the manual description?
In this manual rotation direction of the motor is defined as viewed at the motor from shaft side.
1) Is appropriate voltage applied to the motor?
2) Does ambient temperature exceed the specified range?
3) For a single-phase motor is the capacitor properly connected as per the wiring diagram
shown in page 3.
1) Are the motor and gear head appropriately coupled?
See the instruction manual for the gear head.
2) Is the coupled gear head the same pinion type as the motor shaft?
Characteristics, specifications and dimensions are subject to change without notice.
