SAFETY INSTRUCTIONS
S
As a commissioning or service engineer, you have successfully completed training on
the repair of automation plants. Moreover, you are authorized to start up, ground and
label circuits and equipment in accordance with safety engineering standards.
Residual dangers
This is a state-of-the-art device that is safe to operate. The performance and scope of
supply of the device cover only a small proportion of test and measuring equipment
however. In addition, equipment planners, installers and operators should plan,
implement and respond to the safety engineering considerations of measurement
technology in such a way as to minimize residual dangers. Automation equipment and
devices must be designed so as to ensure adequate protection or locking against
unintentional actuation (e.g. access control, password protection, etc.). When devices are
working in a network, these networks must be designed in such a way that malfunctions
in individual nodes can be detected and shut down. Safety precautions must be taken
both in terms of hardware and firmware, so that a line break or other interruptions to
signal transmission do not cause undefined states or loss of data in the automation
device.
