Focus on IEC standard – Electrical Installation Guide
The standard gives a list of the main requirements applicable to PMD with guidance about sensors to use in case sensors are requested. Devices intended to perform monitoring have various characteristics which require a shared reference system. According to this standard, devices have a code denoting their installation options, operating temperature range and accuracy class.
