This part of GB 7260 is applicable to electronic uninterruptible power supply equipment with energy storage devices in the DC link. This section references the relevant content of GB 4943-2001 and IEC 60950-1:2001. The main function of the uninterruptible power supply (UPS) included in this section is to ensure the continuity of AC power output. UPS can also maintain the specified characteristics of the power supply, thereby improving the quality of the power supply. The notes on regional differences in relevant chapters of GB4943-2001 and IEC 60950-1:2001 also apply. This section applies to mobile, stationary, fixed, or embedded UPS intended for installation in restricted access areas for low-voltage distribution systems. This section specifies the requirements for ensuring the safety of maintenance personnel. This section aims to ensure the safety of installing, operating, and maintaining UPS according to the manufacturer's prescribed methods. UPS can be a single UPS unit or an interconnected UPS system. This section does not include DC powered electronic ballasts (IEC 60347 and IEC 60925) and UPs based on rotating motors. General regulations and safety requirements for UPS intended for installation in the operator's reach area are specified in GB 7260.1, and electromagnetic compatibility (EMC) requirements and definitions are specified in GB 7260.2
