BS EN 55014-2:1997+A2:2008, CISPR 14-2:1997

1.1 This standard deals with the electromagnetic immunity of appliances and similar apparatus for
household and similar purposes that use electricity, as well as electric toys and electric tools, the rated
voltage of the apparatus being not more than 250 V for single-phase apparatus to be connected to phase
and neutral, and 480 V for other apparatus.
Apparatus may incorporate motors, heating elements or their combination, may contain electric or
electronic circuitry, and may be powered by the mains, by transformer , by batteries, or by any other
electrical power source.
Apparatus not intended for household use, but which nevertheless may require the immunity level, such
as apparatus intended to be used by laymen in shops, in light industry and on farms, are within the scope
of this standard, a s far as they are included in CISPR 14-1 , and in addition:
— microwave ovens for domestic use and catering;
— cooking hobs and cooking ovens, heated by means of r.f. energy, (single- and multiple-zone) induction
cooking appliances;
— appliances for personal care equipped with radiators in the range from UV to IR, inclusive
(this includes visible light).
1.2 This standard does not apply to:
— equipment for lighting purposes;
— apparatus designed exclusively for heavy industrial purposes;
— apparatus intended to be part of the fixed electrical installation of buildings (such as fuses, circuit
breakers, cables and switches);
— apparatus intended to be used in locations where special electromagnetic conditions prevail, such as
the presence of high e.m. fields (for example in the vicinity of a broadcast transmitting station), or where
high pulses occur on the power network (such as in a power generator station);
— radio and television receivers, audio and video equipment, and electronic music instruments other
than toys ;
— medical electrical appliances;
— personal computers and similar equipment other than toys ;
— radio transmitters;
— apparatus designed to be used exclusively in vehicles;
— babies surveillance systems.
1.3 Immunity requirements in the frequency range 0 Hz to 400 GHz are covered.
1.4 The effects of electromagnetic phenomena relating to the safety of apparatus are excluded from this
standard and are covered by other standards, for example IEC 335.
Abnormal operation of the apparatus (such as simulated faults in the electric circuitry for testing purposes)
is not taken into consideration.
NOTE Attention is drawn to the fact that additional requirements may be necessary for apparatus intended to be used on board
ships or aircraft.
1.5 The object of this standard is to specify the immunity requirements for apparatus defined in the scope
in relation to continuous and transient, conducted and radiated electromagnetic disturbances, including
electrostatic discharges.
These requirements represent essential electromagnetic compatibility immunity requirements.
NOTE In special cases situations will arise where the level of disturbances may exceed the test values specified in this standard. In
these instances special mitigation measure may have to be employed.

This part of IEC 62040 applies to movable, stationary, fixed or built-in UPS for use in lowvoltage distribution systems and that are intended to be installed in an area accessible by an ordinary person or in a restricted access area as applicable, that deliver fixed frequency AC output voltage with port voltages not exceeding 1 000 V AC or 1 500 V DC and that include an energy storage device. It applies to pluggable and to permanently connected UPS, whether consisting of a system of interconnected units or of independent units, subject to installing, operating and maintaining the UPS in the manner prescribed by the manufacturer.

NOTE 1 Typical UPS configurations, including voltage and/or frequency converters and other topologies, are described in IEC 62040-3, the test and performance product standard for UPS.

NOTE 2 UPS generally connect to their energy storage device through a DC link. A chemical battery is used throughout the standard as an example of an energy storage device. Alternative devices exist, and as such, where "battery" appears in the text of this document, this is to be understood as "energy storage device".

This document specifies requirements to ensure safety for the ordinary person who comes into contact with the UPS and, where specifically stated, for the skilled person. The objective is to reduce risks of fire, electric shock, thermal, energy and mechanical hazards during use and operation and, where specifically stated, during service and maintenance.

This product standard is harmonized with the applicable parts of group safety publication IEC 62477-1:2012 for power electronic converter systems and contains additional requirements relevant to UPS.

This document does not cover:

• UPS that have a DC output; • systems for operation on moving platforms including, but not limited to, aircrafts, ships and motor vehicles;

• external AC or DC input and output distribution boards covered by their specific product standard;

• stand-alone static transfer systems (STS) covered by IEC 62310-1; • systems wherein the output voltage is directly derived from a rotating machine;

• telecommunications apparatus other than UPS for such apparatus; • functional safety aspects covered by IEC 61508 (all parts).

NOTE 3 Even if this document does not cover the applications listed above, it is commonly taken as a guide for such applications. NOTE 4 Specialized UPS applications are generally governed by additional requirements covered elsewhere, for example UPS for medical applications.
