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
Motor: -10 to +50 °C (+14 to +122 °F) (non-freezing)
Driver: 0 to +40 °C (+32 to +104 °F) (non-freezing)
•Operating ambient humidity 85% or less (non-condensing)
•Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or
liquid
•Area not exposed to direct sun
•Area free of excessive amount of dust, iron particles or the like
•Area not subject to splashing water (rain, 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
 Installing the motor
The motor can be installed in any direction. Install the motor onto an appropriate
flat metal plate having excellent vibration resistance and heat conductivity.
When installing the motor, secure it with four bolts (not supplied) through the
four mounting holes. Do not leave a gap between the motor and metal plate.
Note Insert the pilot located on the motor's installation surface into the
mounting plate's pilot hole.

 Installing the driver
● Installation direction
Use a DIN rail 35 mm (1.38 in.) wide to mount the driver. Provide 50 mm
(1.97 in.) clearances in the horizontal and vertical directions between the driver
and enclosure or other equipment within the enclosure.
Refer to the following figure for the required distances between adjacent drivers
when two or more drivers are installed in parallel.
Note Be sure to install (position) the driver vertically. When the driver is
installed in any position other than vertical, the heat radiation
capability of the driver will drop.
•CRD503-KP, CRD507-KP
Two or more CRD503-KP and
CRD507-KP units can be placed in
contact with each other in the horizontal
direction. Provide a clearance of 50 mm
(1.97 in.) or more in the vertical direction.
•CRD514-KP
Provide a clearance of 20 mm (0.79 in.)
or more in the horizontal direction, and
50 mm (1.97 in.) or more in the vertical
direction.
● Installation method
Push up the driver’s DIN lever until it locks. Hang the hook at the rear to the DIN
rail, and push in the driver. After installation, fix the both sides of the driver with
an end plate.
Removing from DIN rail
Pull the DIN lever down until it locks using a
flat tip screwdriver, and lift the bottom of the
driver to remove it from the rail.Use a force of
about 10 to 20 N (2.2 to 4.5 lb.) to pull the DIN
lever down to lock it. Excessive force may
damage the DIN lever.

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 accompany a
“Warning” symbol may result in serious injury or death.
General
•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.
•The motor will lose its holding torque when the power supply or motor
excitation turned off. If this product is used in a vertical application, be sure to
provide a measure for the position retention of moving parts. Failure to provide
such a measure may cause the moving parts to fall, resulting in injury or
damage to the equipment.
•With certain types of alarms (protective functions), the motor may stop when
the alarm generates and the holding torque will be lost as a result. This will
result in injury or damage to equipment.
•When an alarm is generated, first remove the cause and then clear the alarm.
Continuing the operation without removing the cause of the problem may
cause malfunction of the motor and driver, leading to injury or damage to
equipment.

4
•Connection
•Keep the driver’s input-power voltage within the specified range to avoid fire.
•For the driver's power supply, use a DC power supply with reinforced
insulation on its primary and secondary sides. Failure to do so may result in
electric shock.
•Connect the cables securely according to the wiring diagram in order to
prevent fire.
•Do not forcibly bend, pull or pinch the power supply cable and motor cable.
Doing so may cause a fire. This will cause stress to the connecting section
and may result in damage to equipment.
Operation
•Turn off the driver 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 turn the excitation to off while the motor is operating. The motor will
stop and lose its holding ability, which may result in injury or damage to
equipment.
•Configure an interlock circuit using a sequence program so that when a
RS-485 communication error occurs, the entire system including the driver will
operate safely.
Repair, disassembly and modification
•Do not disassemble or modify the motor and driver. This may cause injury.
Refer all such internal inspections and repairs to the branch or sales office
from which you purchased the product.
Handling the product without observing the instructions that accompany a
“Caution” symbol may result in injury or property damage.
General
•Do not use the motor and driver beyond its specifications, or injury or damage
to equipment may result.
•Keep your fingers and objects out of the openings in the motor and driver, or
fire or injury may result.
•Do not touch the motor and driver during operation or immediately after
stopping. The surface is hot and may cause a skin burn(s).
Transportation
•Do not hold the motor output shaft or motor cable. This may cause injury.
Installation
•Install the motor and driver in the enclosure in order to prevent injury.
•Keep the area around the motor and driver free of combustible materials in
order to prevent fire or a skin burn(s).
•Provide a cover over the rotating parts (output shaft) of the motor to prevent
injury.
Operation
•Use a motor and driver only in the specified combination. An incorrect
combination may cause a fire.
•Provide an emergency stop device or emergency stop circuit external to the
equipment so that the entire equipment will operate safely in the event of a
system failure or malfunction. Failure to do so may result in injury.
•Before supplying power to the driver, turn all control input to the driver to OFF.
Otherwise, the motor may start suddenly at power ON and cause injury or
damage to equipment.
•Set the speed and acceleration/deceleration rate at reasonable levels.
Otherwise, the motor will misstep and the moving part may move in an
unexpected direction, resulting in injury or damage to equipment.
•Do not touch the rotating part (output shaft) during operation. This may cause
injury.
•Before moving the motor directly with the hands, confirm that the power supply
or motor excitation turned off and motor current is cut off. Failure not to do so
may result in 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 below in a conspicuous position. Failure to
do so may result in skin burn(s).
Warning label
•Immediately when trouble has occurred, stop running and turn off the driver
power. Failure to do so may result in fire or injury.
•Static electricity may cause the driver to malfunction or suffer damage. While
the driver is receiving power, do not touch the driver. Use only an insulated
screwdriver to adjust the driver's switches.
Disposal
•To dispose of the motor and driver, disassemble it into parts and components
as much as possible and dispose of individual parts/components as industrial
waste. If you have any question, contact your nearest Oriental Motor branch or
sales office
