Danger

[General]
Do not use this product for the following applications:
1. Medical equipment used to maintain, control or otherwise affect human life or physical health
2. Mechanisms and machinery designed for the purpose of moving or transporting people
3. Important safety parts of machinery
This product has not been planned or designed for applications requiring high levels of safety. Use of
this product in such applications may jeopardize the safety of human life. The warranty covers only the
product as it is delivered.


INTELLIGENT ACTUATOR

[Installation]
Do not use this product in a place exposed to ignitable, inflammable or explosive substances. The
product may ignite, burn or explode.
Avoid using the product in a place where the main unit or controller may come in contact with water or
oil droplets.
Never cut and/or reconnect the cables supplied with the product for the purpose of extending or
shortening the cable length. Doing so may result in fire.

[Operation]
If you are using a pace maker or other mechanical implant, do not come within one meter of the
product. The strong magnetic field generated by the product may cause the pace maker, etc., to
malfunction.
Do not pour water onto the product. Spraying water over the product, washing it with water or using it in
water may cause the product to malfunction, resulting in injury, electric shock, fire, etc.

[Maintenance, Inspection, Repair]
Never modify the product. Unauthorized modification may cause the product to malfunction, resulting in
injury, electric shock, fire, etc.
Do not disassemble and reassemble the components relating to the basic structure of the product or its
performance and function. Doing so may result in injury, electric shock, fire, etc.

Warning

[General]
Do not use the product outside the specifications. Using the product outside the specifications may
cause it to fail, stop functioning or sustain damage. It may also significantly reduce the service life of the
product. In particular, observe the maximum loading capacity and speed.

[Installation]
If the machine will stop in the case of system problem such as emergency stop or power failure, design
a safety circuit or other device that will prevent equipment damage or injury.
Be sure to provide Class D grounding for the controller and actuator (formerly Class 3 grounding:
Grounding resistance at 100
or less). Leakage current may cause electric shock or malfunction.
Before supplying power to and operating the product, always check the operation area of the equipment
to ensure safety. Supplying power to the product carelessly may cause electric shock or injury due to
contact with the moving parts.
Wire the product correctly by referring to the operation manual. Securely connect the cables and
connectors so that they will not be disconnected or come loose. Failure to do so may cause the product
to malfunction or cause fire.

[Operation]
Do not touch the terminal block or various switches while the power is supplied to the product. Failure to
observe this instruction may result in electric shock or malfunction.
Before operating the moving parts of the product by hand (for the purpose of manual positioning, etc.),
confirm that the servo is turned off (using the teaching pendant). Failure to observe this instruction may
result in injury.
The cables supplied with the product are flexible, but they are not robot cables. Do not store the cables
in a movable cable duct (cable bearer, etc.) that bends more than the specified bending radius.
Do not scratch the cables. Scratching, forcibly bending, pulling, winding, crushing with heavy object or
pinching a cable may cause it to leak current or lose continuity, resulting in fire, electric shock,
malfunction, etc.


INTELLIGENT ACTUATOR

Turn off the power to the product in the event of power failure. Failure to do so may cause the product
to suddenly start moving when the power is restored, thus resulting in injury or product damage.
If the product is generating heat, smoke or a strange smell, turn off the power immediately. Continuing
to use the product may result in product damage or fire.
If any of the internal protective devices (alarms) of the product has actuated, turn off the power
immediately. Continuing to use the product may result in product damage or injury due to malfunction.
Once the power supply is cut off, investigate and remove the cause and then turn on the power again.
If the LEDs on the product do not illuminate after turning on the power, turn off the power immediately.
The protective device (fuse, etc.) on the live side may remain active. Request repair to the IAI sales
office from which you purchased the product.

[Maintenance, Inspection, Repair]
Before conducting maintenance/inspection, parts replacement or other operations on the product,
completely shut down the power supply. At this time, take the following measures:
1. Display a sign that reads, WORK IN PROGRESS. DO NOT TURN ON POWER at a conspicuous
place, in order to prevent a person other than the operator from accidentally turning on the power
while the operation is working.
2. When two or more operators are to perform maintenance/inspection together, always call out every
time the power is turned on/off or an axis is moved in order to ensure safety.

[Disposal]
Do not throw the product into fire. The product may burst or generate toxic gases.

Caution

[Installation]
Do not use the product under direct sunlight (UV ray), in a place exposed to dust, salt or iron powder, in
a humid place, or in an atmosphere of organic solvent, phosphate-ester machine oil, sulfur dioxide gas,
chlorine gas, acids, etc. The product may lose its function over a short period of time, or exhibit a
sudden drop in performance or its service life may be significantly reduced.
Do not use the product in an atmosphere of corrosive gases (sulfuric acid or hydrochloric acid),
inflammable gases or ignitable liquids. Rust may form and reduce the structural strength or the motor
may ignite or explode.
When using the product in any of the places specified below, provide a sufficient shield. Failure to do so
may result in malfunction:
1. Place where large current or high magnetic field is present
2. Place where welding or other operations are performed that cause arc discharge
3. Place subject to electrostatic noise
4. Place with potential exposure to radiation
Install the main unit and controller in a place subject to as little dust as possible. Installing them in a
dusty place may result in malfunction.
Do not install the product in a place subject to large vibration or impact (4.9 m/s
2
or more). Doing so
may result in the malfunctioning of the product.
Provide an emergency-stop device in a readily accessible position so the device can be actuated
immediately upon occurrence of a dangerous situation during operation. Lack of such device in an
appropriate position may result in injury.
Provide sufficient maintenance space when installing the product. Routine
