damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Standards
See section Standards and approvals (Page 15).
Recycling and disposal
Since the S7-300 components only contain low levels of harmful substances, they are
suitable for recycling. For ecologically compatible recycling and disposal of your old device,
contact a certificated disposal service for electronic scrap.
Note on IT security
Siemens offers IT security mechanisms for its automation and drive product portfolio in order
to support the safe operation of the plant/machine. We recommend that you inform yourself
regularly on the IT security developments regarding your products. You can find information
on this on the Internet (http://support.automation.siemens.com).
You can register for a product-specific newsletter here.
For the safe operation of a plant/machine, however, it is also necessary to integrate the
automation components into an overall IT security concept for the entire plant/machine,
which corresponds to the state-of-the-art IT technology. You can find information on this on
the Internet (http://www.siemens.com/industrialsecurity).
Products used from other manufacturers should also be taken into account here.

Field of application Noise emission requirements Noise immunity requirements
Industry EN 61000-6-4: 2007 EN 61000-6-2: 2005
Use in residential areas
Note
The S7-300 is designed for use in industrial areas; using it in residential areas could disturb
radio and TV reception.
To operate an S7-300 in a residential area, it's RF emission must comply with Limit Value
Class B to EN 55011.
Suitable measures for achieving the required Class B radio interference level include, for
example:
● S7-300 installation in grounded switch cabinets / cubicles
● Use of noise filters in the supply lines

S7-300 Module data
20 Manual, 02/2013, A5E00105505-08
1.2 Electromagnetic compatibility
Definition
Electromagnetic compatibility (EMC) is the ability of an electrical installation to function
satisfactorily in its electromagnetic environment without interfering with that environment.
The S7-300 modules also satisfy requirements of EMC legislation for the European domestic
market. Compliance of the S7-300 system with specifications and directives on electric
design is prerequisite.
