1 Safety Instructions
These safety instructions are intended to prevent hazardous situations
and/or equipment damage. These instructions indicate the level of
potential hazard with the labels of "Caution," "Warning" or "Danger."
They are all important notes for safety and must be followed in addition
to International Standards (ISO/IEC) *1) , and other safety regulations.
*1) ISO 4414: Pneumatic fluid power - General rules relating to systems.
ISO 4413: Hydraulic fluid power - General rules relating to systems.
IEC 60204-1: Safety of machinery - Electrical equipment of machines.
(Part 1: General requirements)
ISO 10218-1: Robots and robotic devices - Safety requirements for
industrial robots - Part 1: Robots.
• Refer to product catalogue, Operation Manual and Handling
Precautions for SMC Products for additional information.
• Keep this manual in a safe place for future reference.
Caution indicates a hazard with a low level of risk which, if
Caution
not avoided, could result in minor or moderate injury.
Warning indicates a hazard with a medium level of risk
Warning
which, if not avoided, could result in death or serious injury.
Danger indicates a hazard with a high level of risk which, if
Danger
not avoided, will result in death or serious injury.
Warning
• Always ensure compliance with relevant safety laws and
standards.
• All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.
• This product is class A equipment intended for use in an industrial
environment. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to conducted
or radiated disturbances.
Otherwise electric shock, malfunction or product damage can result.
