This part of IEC 62974 specifies product and performance requirements for devices that fall
under the heading of “monitoring and measuring systems used for data collection, gathering
and analysis”, for industrial, commercial and similar use rated below or equal to 1 kV AC and
1,5 kV DC.
These devices are fixed and are intended to be used indoors as panel-mounted devices, or as
modular devices fixed on a DIN rail, or as housing devices fixed on a DIN rail, or as devices
fixed by other means inside a cabinet.
These devices are used to upload or download information (energy measured on loads, power
metering and monitoring data, temperature information…), mainly for energy efficiency
purposes. These devices are known as energy servers, energy data loggers, data gateways
and I/O data concentrators.
This standard does not cover:
• devices used only in the consumer market (living quarters) or household;
• devices used in the smart metering infrastructure (e.g. smart meters);
• devices used in the smart grid infrastructure;
• devices used as IT servers in the information technology business;
• power metering and monitoring devices: PMD with additional functions (e.g. energy data
logger function);
• I/O data concentrators already covered by a specific product standard;
• communication protocols and interoperability;
• power quality instruments (PQI);
• software used for the data collection and analysis of the power quality for the supply side.
