Safety information
2.1 General safety instructions
Additional notes for built-in units
The rear of the device constitutes open equipment.
The rear of the device constitutes open equipment. This means that the device may only be
installed in an enclosure or cabinet which provides front access for operating the device.
The enclosure, the cabinet or the electrical operating rooms must provide protection against
electric shock and the spread of fire. The requirements regarding the mechanical strength
must also be taken into account.
Access to the enclosure or cabinet in which the device is installed should only be possible
by means of a key or tool and for trained and authorized personnel.
Electrocution risk when control cabinet is open
When you open the control cabinet, there may be a dangerous voltage at certain areas or
components.
If you touch these areas or components, you may be killed by electric shock.
Always disconnect the control cabinet from the mains before opening it. Do not plug in or
pull out the system component during operation.
ESD
An electrostatically sensitive device is equipped with electronic components. Due to their
design, electronic components are sensitive to overvoltage and thus to the discharge of
static electricity. Note the corresponding regulations when handling ESD.
Industrial Security
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens' products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. use of firewalls and network
segmentation) are in place.
For additional information on industrial security measures that may be implemented,please
visit (http://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply latest updates may increase customer's exposure to
cyber threats.
