use as an internal component for general industrial equipment, and must not be
used for any other purpose. Oriental Motor Co., Ltd. is not responsible for any
damage caused through failure to observe this warning.
Standard and CE Marking
Motors are recognized by UL and certified by CQC. Recognized name and
certified name are motor model name.
Voluntary display of the CE mark conforming to the Low Voltage Directives.
Standards
UL 1004-1, UL 1004-3, CSA C22.2 No.100, CSA C22.2 No.77, GB 12350
Standards File No.
UL File No. E64197, CQC
Applicable Standards
EN 60034-1, EN 60034-5, EN 60664-1, EN 60950-1
A Running Heating Test and a Locked-Rotor Test have been conducted with
a gearhead. For the 90 W reversible motor, tests have been conducted with a
gearhead and a radiation plate [a radiation plate size: 200 × 200 mm (7.87 ×
7.87 in.), thickness: 5 mm (0.20 in.), material: aluminum].
Installation conditions
Overvoltage category II, Pollution degree 2, Class I equipment (For EN
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.
Standards for accessories
Capacitor: UL File No.E83671 (CYWT2), VDE License Nos.112847
(capacitors with a rated voltage of 250 VAC),
114747 (capacitors with a rated voltage of 450 VAC)
Capacitor cap: UL File No.E56078 (YDTU2)
Hazardous substances
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.
Caution
Handling the product without observing the
instructions that accompany a “Caution” symbol
may result in injury or property damage.
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 Iequipment. 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.
• 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.
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 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.
• 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
(158 °F), 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).
