Part 1 Installation
No. Task Note
(2) Wiring the cables
 Use IAI’s genuine cables to connect the actuator and controller or connect a
teaching tool, etc.
 Do not damage, forcibly bend, pull, loop round an object or pinch the cables or
place heavy articles on top. Current leak or poor electrical continuity may occur,
resulting in fire, electric shock or malfunction.
 Wire the product correctly after turning off the power.
 When wiring a DC power supply (+24 V), pay attention to the positive and
negative polarities.
Connecting the wires in wrong polarities may result in fire, product failure or
malfunction.
 Be sure to connect the cable connectors without fail and firmly. Failing to do so
may result in fire, electric shock or product malfunction.
 Do not cut and reconnect the cables of the product to extend or shorten the
cables. Doing so may result in fire or product malfunction.
(3) Grounding
 Be sure to provide class D (former class 3) grounding for the controller.
Grounding is required to prevent electric shock and electrostatic charges,
improve noise resistance and suppress unnecessary electromagnetic radiation.
(4) Safety measures
 Implement safety measures (such as installing safety fences, etc.) to prevent
entry into the movement range of the robot when the product is moving or can
be moved. Contacting the moving robot may result in death or serious injury.
 Be sure to provide an emergency stop circuit so that the product can be stopped
immediately in case of emergency during operation.
4 Installation/
startup
 Implement safety measures so that the product cannot be started only by turning
on the power. If the product starts suddenly, injury or product damage may
result.
 Implement safety measures so that the product will not start upon cancellation of
an emergency stop or recovery of power following a power outage. Failure to do
so may result in injury, equipment damage, etc.
 Put up a sign saying “WORK IN PROGRESS. DO NOT TURN ON POWER,”
etc., during installation, adjustment, etc. If the power is accidently turned on,
electric shock or injury may result.
 Implement measures to prevent the work part, etc., from dropping due to a
power outage or emergency stop.
 Ensure safety by wearing protective gloves, protective goggles and/or safety
shoes, as necessary.
 Do not insert fingers and objects into openings in the product. Doing so may
result in injury, electric shock, product damage, fire, etc.
 When releasing the brake of a vertically installed actuator, be careful not to
pinch your hand or damage the work part, etc., due to the slider dropping by its
dead weight.
5 Teaching  Whenever possible, perform teaching from outside the safety fences. If teaching
must be performed inside the safety fences, prepare “work rules” and make sure
the operator understands the procedures thoroughly.
 When working inside the safety fences, the operator should carry a handy
emergency stop switch so that the operation can be stopped any time when an
abnormality occurs.
 When working inside the safety fences, appoint a safety watcher in addition to
the operator so that the operation can be stopped any time when an abnormality
occurs. The safety watcher must also make sure the switches are not operated
inadvertently by a third party.
 Put up a sign saying “WORK IN PROGRESS” in a conspicuous location.
 When releasing the brake of a vertically installed actuator, be careful not to
pinch your hand or damage the work part, etc., due to the slider dropping by its
dead weight.
* Safety fences --- Indicate the movement range if safety fences are not provided.
