SAFETY INSTRUCTIONS

Qualified personnel
Qualified persons means persons entrusted with the installation, fitting, commissioning
and operation of the product who possess the appropriate qualifications for their func
tion.
This includes people who meet at least one of the three following requirements:
SKnowledge of the safety concepts of measurement and automation technology is a
requirement and as project personnel, they must be familiar with these concepts.
SAs measurement or automation plant operating personnel, they been instructed how
to handle the machinery. They are familiar with the operation of the equipment and
technologies described in this documentation.
SAs commissioning engineers or service engineers, they have successfully completed
the training to qualify them to repair the automation systems. They are also author
ized to activate, ground and label circuits and equipment in accordance with safety
engineering standards.
Working safely
SThe device must not be directly connected to the power supply system. The supply
voltage must be between 12 and 30VDC.
SError messages should only be acknowledged once the cause of the error is removed
and no further danger exists.
SAutomation equipment and devices must be designed in such a way that adequate
protection or locking against unintentional actuation is provided (e.g. access checks,
password protection, etc.).
SFor those devices operating in networks, safety precautions must be taken both in
terms of hardware and software, so that a line break or other interruptions to signal
transmission do not cause undefined states or loss of data in the automation device.
SAfter making settings and carrying out activities that are password-protected, ensure
that any controls that may be connected remain in a safe condition until the switching
performance of the device has been tested.
Additional safety precautions
Additional safety precautions to meet the requirements of the relevant national and local
accident prevention regulations must be taken in plants where malfunctions could cause
major damage, loss of data or even personal injury.
The scope of supply and performance of the device covers only a small area of measure
ment technology. Before starting up the device in a system, a project planning and risk
analysis must first be implemented, taking into account all the safety aspects of meas
urement and automation technology so that residual risks are minimized. This particu
larly concerns personal and machine protection. In the event of a fault, the relevant pre
cautions must establish safe operating conditions.
