Dangers of interference. EMC and safety

In safety-related systems, the issue of electromagnetic compatibility (EMC) is clearly even more important than in other installations. First, it is important that the equipment has sufficient immunity to avoid malfunctions due to electromagnetic interference, which might lead to danger either to people or property.
