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.
 Securely connect the cables and connectors so that they will not be disconnected or
come loose. 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 Installation/
startup
(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.
 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 the vertically installed actuator, be careful not to let the
actuator drop due to its dead weight, causing pinched hands or damaged work part, etc.
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.
