EN IEC 62040-2 applies to UPS units intended to be installed as referenced below:
– installed as a unit or in UPS systems comprising a number of interconnected UPS and associated control/switchgear forming a single power system
– installed in any operator accessible area or in separated electrical locations, connected to low voltage supply networks for either industrial or residential, commercial and light industrial environments
EN IEC 62040-2 is intended as a product standard allowing the EMC conformity assessment of products that fall under 4 different categories. Each category is based on the intended use of the equipment, is referenced as intended environment, and has specific test requirements for both emissions and immunity. Compliant test results can allow manufacturers to claim compliance to the EU EMC Directive, 2014/30/EU
Environments
First Environment:
Residential, commercial, and light industrial locations connected without intermediate transformers to low voltage public mains supply
Second Environment:
Residential, commercial, and light industrial locations other than those directly connected to a low voltage public main that supplies buildings used for residential purposes.
Categories
Category 1
UPS intended for use without any restriction in the first environment, useable for residential applications
Category 2
UPS with an output current not to exceed 16 A, and intended for use in the second environment. Note that UPS under this criteria can be used in the first environment when special consideration is used specific to connection method:
-Through industrial plugs or sockets
-Through national plugs or sockets
-Permanently
Category 3
UPS with an output current exceeding 16 A and for intended use in the second environment. Common uses for this category are UPS used in commercial or industrial buildings and installation, with a minimum boundary of 30 meters from other buildings that are considered as first environment.
Category 4
UPS for use in complex environments, and may be permanently installed.
The requirements have been selected so as to ensure an adequate level of electromagnetic compatibility (EMC) for UPS at public and industrial locations. These levels cannot, however, cover extreme cases, which may occur in any location but with extremely low probability of occurrence.
EN IEC 62040-2 takes into account the differing test conditions necessary to encompass the range of physical sizes and power ratings of UPS.
A UPS unit or system shall meet the relevant requirements of this part of EN IEC 62040-2 as a stand-alone product. EMC phenomena produced by any customers’ load connected to the output of the UPS equipment shall not be taken into account. This part of EN IEC 62040 does not cover DC supplied electronic ballast or UPS based on rotating machines.
