EN 62040 – The UPS Standard

Although externally all uninterruptible power supplies (UPS) systems look alike, an often black box, LCD screen and multiple ports at the rear, it is the superior internal component structure of CertaUPS’ units that make them a market leader in design quality, reliability.

As an uninterruptible power supply manufacturer, CertaUPS designs and tests the system to comply with all relevant regulatory requirements including the key standard for UPS systems, EN 62040.

EN62040 comprises three parts, adopting sections outlined in the International Electrotechical Commission, IEC 62040 which has an additional part, part 4 that includes environmental regulations relating to the UPS.

EN 62040 comprises four parts:

  • EN 62040-1:2008 Uninterruptible power systems (UPS) – Part 1: General and safety requirements for UPS
  • EN 62040-2:2006 Uninterruptible power systems (UPS) – Part 2: Electromagnetic compatibility (EMC) requirements
  • EN 62040-3:2011 Uninterruptible power systems (UPS) – Part 3: Method of specifying the performance and test requirements
  • IEC 62040-4:2013 Uninterruptible power systems (UPS) – Part 4: Environmental aspects – Requirements and reporting

Part 1 – EN 62040-1:2008: General and safety:
Applying to both pluggable and permanently connected UPS, this part refers to UPS in low voltage distribution systems that deliver fixed frequency AC output voltage with port voltages not exceeding 1000VAC or 15000VDC.

This part is harmonised with EN60950:2006 and IEC 62477-1:2012 as are parts 2, 3 and 4.

Part 2: EN 62040-2:2006 Electromagnetic compatibility (EMC):
Taking precedence over all aspects of the generic standards, part 2 applies to individual UPS units or to multiple UPS systems interconnected in a single power supply system that are connected to industrial or public low-voltage networks.

Part 3: EN 62040-3:2011 Method of specifying the performance and test:
This International Standard applies to movable, stationary and fixed electronic uninterruptible power systems (UPS) that deliver single or three-phase fixed frequency AC output voltage not exceeding 1 000 VAC and that incorporate an energy storage system, generally connected through a DC link.

This standard is intended to specify performance and test requirements of a complete UPS and not of individual UPS functional units. The individual UPS functional units are dealt with in IEC publications referred to in the bibliography that apply so far that they are not in contradiction with this standard.

PArt 4: IEC 62040-4:2013 Environmental aspects – Requirements and reporting
This part specifies the process ad requirements to declare the environmental aspects concerning the UPS, with the goal of promoting a reduction of any adverse environmental impact during a complete UPS life cycle.
