Safety instructions
Working safely
S The device must not be directly connected to the power supply system.
S Error messages may only be acknowledged once the cause of the error is
removed and there is no further danger.
S Maintenance and repair work on an open device with the power on may
only be carried out by trained personnel who are aware of the dangers
involved.
S Automation 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.).
S For those devices operating in networks, safety precautions must be taken
both in terms of hardware and software, so that a line break or other inter­
ruptions to signal transmission do not cause undefined states or loss of data
in the automation device.
S After implementing 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 implemented 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
measurement 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 the measurement and automation technology so that residual
risks are minimized. This particularly concerns personal and machine protec­
tion. In the event of a fault, the relevant precautions must establish safe oper­
ating conditions.
