| Nosaukums | This standard applies to electronic indirect a.c. convertor systems with an electrical energy storage device in the d;c. link. The primary function of the uninterruptible power system (UPS) covered by this Standard is to ensure continuity of an alternating power source The uninterruptible power system may also serve to improve the quality of the power source by keeping it within specified characteristics This Standard is applicable to UPS for use on distribution systems up to 1000 V a.c. which are movable, stationary, fixed and for building in This Standard applies to UPS intended to be installed in restricted access locations and specifies requirements to ensure safety for the service personnel 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 or a.c. supplied electronic lamp control gears, or UPS based on rotating machines. Even if this standard does not cover all types of UPS, it may be taken as a guide for such UPS. Requirements additional to those specified in this Standard may be necessary for specific applications, e.g. 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 physical connections to the patient |
