Safety Guide
Intro-1
Safety Guide
The Safety Guide is intended to permit safe use of the product and thus to prevent risks and property
damage.
Be sure to read it before handling the product.
Safety Precautions for Our Products
Common safety precautions for the use of robots in various operations are indicated here.
No.
Operation
Precautions
1 Model
Selection
●This product is not intended or designed for applications where high levels of
safety are required, and so cannot guarantee that human lives will be
protected. Accordingly, do not use it in any of the following applications.
(1) Medical equipment used to maintain, control or otherwise affect human life
or physical health
(2) Mechanisms or machinery designed for the purpose of moving or
transporting people
(vehicles, railway facilities, aviation facilities etc.)
(3) Machinery components essential for safety (safety devices etc.)
●Do not use the product outside the range of the specifications. Otherwise, the
product life may be drastically shortened, and product damage or facilities
stoppage may occur.
●Do not use it in any of the following environments.
(1) Locations with flammable gases, ignitable objects or explosives
(2) Locations with potential exposure to radiation
(3) Locations with ambient temperature or relative humidity exceeding the
specifications range
(4) Locations where radiant heat is applied by direct sunlight or other large heat
source
(5) Locations where condensation occurs due to abrupt temperature changes
(6) Locations with corrosive gases (sulfuric acid, hydrochloric acid etc.)
(7) Locations exposed to significant amounts of dust, salt or iron powder
(8) Locations subject to direct vibration or impact
●For an actuator used in vertical orientation, select a model with brake. If a
model without brake is selected, the moving parts may fall when the power is
turned OFF, causing accidents such as injury or workpiece damage.

No.
Operation
Precautions
2 Transportation ●When transporting heavy objects, do the work with two or more persons or
utilize equipment such as a crane.
●When working with two or more persons, make it clear who is to be in charge
and communicate well with each other to ensure safety.
●During transportation, carefully consider the carrying positions, weight, and
weight balance, and be careful to avoid collisions or dropping.
●Use appropriate transportation measures for transport.
The actuators available for transportation with a crane have eyebolts attached
or tapped holes to mount bolts. Follow the instructions in the instruction
manual for each model.
●Do not climb onto the package.
●Do not put anything heavy that could deform the package on it.
●When using a crane with capacity of 1t or more, have an operator qualified for
crane operation and sling work.
●When using a crane or equivalent equipment, make sure not to suspend loads
exceeding the equipment's rated load.
●Use a hook that is suitable for the load. Consider the safety factor of the hook
in such factors as shear strength. Also, check to make sure that the hook is
free of damage.
●Do not climb on loads suspended from cranes.
●Do not leave loads suspended from cranes for long periods.
●Do not stand under loads suspended from cranes.

Storage and
Preservation
●
For the storage and preservation environment, see the installation
environment. However, give especial consideration to the prevention of
condensation.
●Store the products so as to prevent them from falling over or down in the case
of natural disasters such as earthquakes.
4 Installation
and Startup
(1) Installation of robot body and controller, etc.
●Be sure to securely hold and fix the product (including the workpiece). If the
product falls over, is dropped, or operates abnormally, it may lead to damage
and injury.
Also, be equipped for falls over or down due to natural disasters such as
earthquakes.
●Do not climb on or put anything on the product. Otherwise, this may lead to
accidental falling, injury or damage to the product due to falling objects,
product loss of function or performance degradation, or shortening of product
life.
●When using the product in any of the places specified below, provide sufficient
shielding.
(1) Locations where electrical noise is generated
(2) Locations with strong electrical or magnetic fields
(3) Locations with mains or power lines passing nearby
(4) Locations where the product may come in contact with water, oil or
chemical spray

Safety Guide
Intro-3
(2) Cable wiring
●Use IAI genuine cables for connecting the actuator and controller, and for the
teaching tools.
●Do not scratch cables, bend them forcibly, pull them, coil them, snag them, or
place heavy objects on them. Otherwise, this may lead to fire, electric shock,
or abnormal operation due to leakage or conduction malfunction.
●Perform the wiring for the product after turning OFF the power to the unit, and
avoid miswiring.
●When wiring DC power (+24V), be careful with the positive/negative polarity.
Incorrect connections may lead to fire, product breakdown or abnormal
operation.
●Connect the cable connector securely so that there is no disconnection or
looseness. Otherwise, this may lead to fire, electric shock, or abnormal
operation of the product.
●Never cut or reconnect the cables supplied with the product for the purpose of
extending or shortening the cable length. Otherwise, this may lead to fire or
abnormal operation of the product.
(3) Grounding
●Grounding must be performed, in order to prevent electric shocks or
electrostatic charge, enhance noise-resistant performance and control
unnecessary electromagnetic radiation.
●For the ground terminal on the AC power cable of the controller and the
grounding plate in the control panel, be sure to use a twisted pair cable with
wire thickness 0.5mm2(AWG20 or equivalent) or more for grounding work. For
safeguard grounding, it is necessary to select an appropriate wire diameter for
the load. Perform wiring that satisfies the specifications (electrical equipment
technical standards).
●Perform Class D grounding (former Class 3 grounding, with ground resistance
100Ωor below).

4 Installation
and
Startup
(4) Safety measures
●When working with two or more persons, make it clear who is to be in charge
and communicate well with each other to ensure safety.
●When the product is operating or in the ready mode, take safety measures
(such as the installation of safety/protection fences) so that nobody can enter
the area within the robot's movable range. Contact with an operating robot
may lead to death or serious injury.
●Be sure to install an emergency stop circuit so that the unit can be stopped
immediately in an emergency during operation.
●Take safety measures such that turning the power ON alone will not start up
the unit. Otherwise, this may cause the product to start unexpectedly, leading
to injury or product damage.
●Take safety measures such that emergency stop cancel or recovery after
power failure alone will not start up the unit. Otherwise, this may lead to injury
or equipment damage.
●When installation or adjustment operation is to be performed, display signs
such as "Operating: No Power ON!" etc. Sudden power input may cause
electric shock or injury.
●Take measures to prevent workpieces, etc. from falling during power failures or
emergency stop.
●Wear protection gloves, goggles and safety shoes, as necessary, to secure
safety.
●Do not insert fingers or objects into the openings in the product. Otherwise,
this may lead to injury, electric shock, product damage, or fire.
●When releasing the brake on a vertically oriented actuator, be careful that it
does not fall under its own weight, catching the operator's hand or damaging
workpieces.
5 Teaching ●When working with two or more persons, make it clear who is to be in charge
and communicate well with each other to ensure safety.
●Perform teaching operation from outside the safety/protection fence, if
possible. If operation must be performed within the safety/protection fence,
prepare "Work Regulations" and make sure that all the workers acknowledge
and understand them well.
●When operation is to be performed inside the safety/protection fence,
operators should have emergency stop switches available at hand so that the
unit can be stopped at any time if abnormalities occur.
●When operation is to be performed inside the safety/protection fence, have a
monitor standing by in addition to the operator(s) so that the unit can be
stopped at any time if abnormalities occur. Also, keep watch on the operation
so that a third party cannot operate the switches carelessly.
●Place a sign indicating "Operating" where it can be seen easily.
●When releasing the brake on a vertically oriented actuator, be careful that it
does not fall under its own weight, catching the operator's hand or damaging
workpieces.
* Safety/protection fence: If there is no safety/protection fence, the movable
range should be indicated.
