29、00 2006, Uncontrolled Copy, (c) BSI UNINTERRUPTIBLE POWER SYSTEMS (UPS) Part 1-2: General and safety requirements for UPS used in restricted access locations 1 Scope and specific applications 1.1 Scope This standard applies to electronic uninterruptible power systems with an electrical energy storag
30、e device in the d.c. link. It is to be used with IEC 60950-1 which is referred to in this standard as “RD”. When any item is referred to by the phrase “The definitions or the provisions of item/RD apply”, this phrase is intended to mean that the definitions or provisions in that item of IEC 60950-1
31、apply, except any which are clearly inapplicable to uninterruptible power systems. National requirements additional to those in IEC 60950-1 apply and are found as notes under relevant clauses of the RD. The primary function of the UPS covered by this standard is to ensure continuity of an alternatin
32、g power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. This standard is applicable to UPS which are movable, stationary, fixed or for building-in, for use on low-voltage distribution systems and intended to be installed in re
33、stricted access locations. It specifies requirements to ensure safety for the service person. This standard is intended to ensure the safety of installed UPS, both as a single UPS unit or as a system of interconnected UPS units, subject to installing, operating and maintaining the UPS in the manner
34、prescribed by the manufacturer. This standard does not cover d.c. supplied electronic ballasts (IEC 61347 and IEC 60925) and UPS based on rotating machines. The relevant general and safety requirements for UPS intended to be installed in operator access areas are given in IEC 62040-1-1; electromagne
35、tic compatibility (EMC) requirements and definitions are given in IEC 62040-2. 1.2 Specific applications Even if this standard does not cover all types of UPS, it may be taken as a guide for such equipment. Requirements additional to those specified in this standard may be necessary for specific app
36、lications, for example: UPS intended for operation while exposed, for example, to extremes of temperature; to excessive dust, moisture, or vibration; to flammable gases; to corrosive or explosive atmospheres; electromedical applications with the UPS located within 1,5 m from the patient contact area
37、; UPS subject to transient overvoltages exceeding those for Overvoltage Category II according to IEC 60664, additional protection might be necessary in the mains supply to the UPS.

38、y, (c) BSI UPS intended for use where ingress of water and foreign objects are possible, additional requirements may be necessary; for guidance on such requirements and for relevant testing, see annex H. UPS with trapezoidal output waveforms and long run times (greater than 30 min) are subject to vo
39、ltage distortion tests for the purpose of load compatibility. NOTE For UPS intended to be used in vehicles, on board ships or aircraft, in tropical countries, or on elevations greater than 1 000 m, different requirements may be necessary. 2 Normative references The following referenced documents are
