Fitting connectors on site
If it is necessary to fit connectors on site,
– BFOC connectors and suitable tools can be ordered
– SIEMENS provides this service.
If this is required, please ask your contact for special cables and special lengths.
You will also find the address:
- in our catalog IK PI
- on the Internet (http//www.ad.siemens.de)
Fiber-optic cable connectors are susceptible to contamination and mechanical damage to
the face. Protect open connectors with the supplied dust caps. Only remove the dust cap
immediately before making the connection.

Electromagnetic compatibility of bus cables

Electromagnetic compatibility (EMC)
Electromagnetic compatibility (EMC) is the capability of a electrical equipment to function
satisfactorily in its electromagnetic environment without influencing this environment and
interfering with other equipment belonging to it (in compliance with DIN VDE 0870).
This mutual influence can take the form of electrical, magnetic, and electromagnetic effects.
These effects can spread both over cable connections (for example a common power
supply) or due to radiated interference affecting the cable.
To avoid interference affecting electrical systems, these effects must be reduced to a certain
level. The measures involved in achieving this limitation include the design, construction, and
correct connection of bus cables. The components and bus cables for SIMATIC NET
Industrial Ethernet meet the requirements of the European standards for devices used in an
industrial environment. This is documented by the CE marking.
Note
Adherence to the specified limit values can only be guaranteed when using components
from the SIMATIC NET Industrial Ethernet range exclusively and by keeping to the
installation instructions in this manual!
