Note
The S7-1200 automation system is intended for use in industrial areas; use in residential
areas can have an impact on radio or TV reception. If you use the S7-1200 in residential
areas, you must ensure that its radio interference emission complies with the limit value
Class B in accordance with EN 55011.
Examples of suitable measures for achieving RF interference, level Class B include:
- Installation of the S7-1200 in a grounded control cabinet
- Use of noise filters in the supply lines
Ensure that the radio interference emission complies with Class B in accordance with EN
55011.
Individual acceptance is required (final installation must meet all safety and EMC
requirements of a residential installation).
Electromagnetic compatibility
Electromagnetic Compatibility (EMC) is the ability of an electrical device to operate as
intended in an electromagnetic environment and to operate without emitting levels of
electromagnetic interference (EMI) that may disturb other electrical devices in the vicinity.
