Specifies general and safety requirements for low voltage electronic Uninterruptible Power Systems (UPS) installed in areas with restricted access. This Standard is to be read in conjunction with AS/NZS 60950.1.

This standard applies to electronic uninterruptible power systems with an electrical energy storage 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 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 alternating 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 restricted 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 prescribed by the manufacturer. This standard does not cover d.c. supplied electronic ballasts (IEC 60924 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; electromagnetic compatibility (EMC) requirements and definitions are given in IEC 62040-2.
