WARNING
YAMAHA robots are not designed to be explosion-proof. Do not use the robots and controllers in locations
exposed to explosive or inflammable gases, dust particles or liquid such as gasoline and solvents. Failure to
follow this instruction may cause serious accidents involving injury or death, and lead to fire.

WARNING
• Use the robot controller in locations that support the environmental conditions specified in this manual.
Operation outside the specified environmental range may cause electrical shock, fire, malfunction or product
damage or deterioration.
• The robot controller and programming box must be installed at a location that is outside the robot safety
enclosure yet where it is easy to operate and view robot movement.
• Install the robot controller in locations with enough space to perform work (teaching, inspection, etc.) safely.
Limited space not only makes it difficult to perform work but can also cause injury.
• Install the robot controller in a stable, level location and secure it firmly. Avoid installing the controller upside
down or in a tilted position.
• Provide sufficient clearance around the robot controller for good ventilation. Insufficient clearance may cause
malfunction, breakdown or fire.
