Safety measures
1.
Referring to warning labels and manual
w
WARNING
• Before starting installation or operation of the robot, be sure to read the warning labels and this manual, and
comply with the instructions.
• Never attempt any repair, parts replacement and modification unless described in this manual. These
tasks require specialized technical knowledge and skills and may also involve hazards. Please contact your
distributor for advice.

NOTE
For details on warning labels, see "3. Warning labels".
2.
Draw up "work instructions" and make the operators/workers understand them
w
WARNING
Decide on "work instructions" in cases where personnel must work within the robot safety enclosure to perform
startup or maintenance work. Make sure the workers completely understand these "work instructions".
Decide on "work instructions" for the following items in cases where personnel must work within the robot safety
enclosure to perform teaching, maintenance or inspection tasks. Make sure the workers completely understand these
"work instructions".
1. Robot operating procedures needed for tasks such as startup procedures and handling switches
2. Robot speeds used during tasks such as teaching
3. Methods for workers to signal each other when two or more workers perform tasks
4. Steps that the worker should take when a problem or emergency occurs
5. Steps to take after the robot has come to a stop when the emergency stop device was triggered, including checks for
cancelling the problem or error state and safety checks in order to restart the robot.
6. In cases other than above, the following actions should be taken as needed to prevent hazardous situations due to
sudden or unexpected robot operation or faulty robot operation as listed below.
• Place a display sign on the operator panel
• Ensure the safety of workers performing tasks within the robot safety enclosure
• Clearly specify position and posture during work
Specify a position and posture where worker can constantly check robot movements and immediately move to
avoid trouble if an error/problem occurs
• Take noise prevention measures
• Use methods for signaling operators of related equipment
• Use methods to decide that an error has occurred and identify the type of error
Implement the "work instructions" according to the type of robot, installation location, and type of work task.
When drawing up the "work instructions", make an effort to include opinions from the workers involved, equipment
manufacturer technicians, and workplace safety consultants, etc.

Take safety measures

DANGER
• Never enter the robot movement range while the robot is operating or the main power is turned on. Failure to
follow this warning may cause serious accidents involving injury or death. Install a safety enclosure or a gate
interlock with an area sensor to keep all persons away from the robot movement range.
• When it is necessary to operate the robot while you are within the robot movement range such as for teaching
or maintenance/inspection tasks, always carry the programming box with you so that you can immediately
stop the robot operation in case of an abnormal or hazardous condition. Install an enable device in the
external safety circuit as needed. Also set the robot moving speed to 3% or less. Failure to follow these
instructions may cause serious accidents involving injury or death.
See "7.1 Movement range" for details on the robot's movement range.
