The electromagnetic emissions are not expected to be high enough to ensure that other equipment installed in the vicinity is not unduly affected by the equipment under consideration. However, the device is intended for operation in its intended location. In this regard, this document specifies three different types of electromagnetic environments and Immunity level. For more information on electromagnetic environment issues, refer to IEC TR61000-2-5. This does not include situations such as electrical shock, circuit breaker operation or abnormally high electromagnetic radiation in close proximity. Complex electrical and/or electronic systems are not designed or EMC planning is required at all stages of installation, taking into account the electromagnetic environment, any special requirements and the severity of the fault. This document specifies general EMC requirements applicable to all equipment within its scope.
