scope:

This part of the IEC 62040 series specifies the process and requirements to declare the environmental aspects concerning uninterruptible power systems (UPS), with the goal of promoting reduction of any adverse environmental impact during a complete UPS life cycle. This product standard is harmonized with the applicable generic and horizontal environmental standards and contains additional details relevant to UPS.

This standard applies to movable, stationary and fixed UPS that deliver single or three-phase fixed frequency a.c. output voltage not exceeding 1 000 V a.c. and that present, generally through a d.c. link, an energy storage system and specified in IEC 62040 product standards for UPS (Part 1: Safety, Part 2: EMC and Part 3: Test and performance).

The following applications are excluded from the scope:

- conventional a.c. input and output distribution boards;

- d.c. distribution boards and their associated switches (e.g. switches for batteries, rectifier output or inverter input);

- stand-alone static transfer systems (STS) specified in IEC 62310 product standards for STS (Part 1: Safety, Part 2: EMC and Part 3: Test and performance);

- systems wherein the output voltage is derived from a rotating machine.
