1 Scope
This document describes certain aspects of standardization of LVDC industrial applications.
These industrial applications apply to the secondary economic sector where the processing of resources applies to the production, distribution and storage of physical goods, typically in a factory or similar areas.
The local LVDC distribution can be connected to the public grid (AC or DC) or can work completely off-grid (intentional islanding).
This document provides a practical guideline for the design and planning of industrial LVDC systems, aiming at interoperability amongst different devices.
IEC use case descriptions of the described industry application are part of this document.
NOTE This document is not intended for following applications: railway, ships, vehicles, aircraft, public distribution. But wherever possible and practicable, compatibility of product requirements is considered favourable.
Included is equipment which is especially designed for and intended for use in industrial areas. This includes everything that is concerned with with the commercial extraction, processing and further processing of raw materials or intermediate products into material goods; in particular, machines, plants, storage facilities and transport systems.
Not included is equipment which is especially designed for and intended for use in ordinary buildings:
supporting building equipment (e.g. lighting and HVAC) in buildings or parts of buildings in which machines, plants, storage equipment and transport systems are installed;
building equipment in buildings or parts of buildings in which supporting and administrative production functions are performed (e.g. offices).
