11.4 Electromagnetic compatibility

Use in residential areas
The ET 200eco PN M12‑L distributed I/O system is not intended for use in residential areas.
Using the ET 200eco PN M12‑L distributed I/O system in residential areas can affect radio or
television reception.
11.4 Electromagnetic compatibility
Definition
Electromagnetic compatibility is the ability of an electrical apparatus to function in a
satisfactory manner in its electromagnetic environment without affecting this environment.
An ET 200eco PN M12‑L distributed I/O device fulfills the requirements of the EMC law of the
European Union. The prerequisite for this is that the electrical configuration of the
ET 200eco PN M12‑L distributed I/O device complies with the specifications and guidelines for
the electrical configuration.
Pulse-shaped disturbance variables
The table below shows the electromagnetic compatibility of the distributed I/O systems
compared to pulse-shaped disturbance variables.
Table 11-1 Pulse-shaped disturbance variables
Pulse-shaped disturbance variable
Electrostatic discharge according to
IEC 61000-4-2.
Burst pulses (fast transient disturbance
variables) according to IEC 61000-4-4.
High-energy single pulse (surge) to IEC 61000-4-5
• For installation within buildings:
– Signal line < 30 m
• For installation outdoors
– Signal line < 30 m
– Use of shielded IP lines
– Grounding of the shielding at both ends according to IEC 61000-4-5
• Asymmetric coupling
• Symmetric coupling
1 The maximum short-term influencing of analog devices during the duration of the EMC tests can
amount to ±10 % of the full-scale value.
Analog value deviation beyond the limits of the nominal range and diagnostics possible.
