    Abstract - (Show below) - (Hide below)

    Applicable to electronic indirect a.c. convertor systems with an electrical energy storage device in the d.c. link. Main function of the UPS covered is to ensure continuity of an alternative power source. Uninterruptible power system may also serve to improve the quality of the power source by keeping it within specified characteristics. Applies to UPS for use on distribution systems up to 1 000 V a.c. which are movable, stationary, fixed and for building in; intended to be installed in restricted access locations and details requirements for safety of service personnel. 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.
