Scope

1.1 Scope
This Part of GB 7260 applies to electronic uninterruptible power systems with an
electrical energy storage device in the d.c. link. This Part refers to the relevant contents
of GB 4943-2001 and IEC 60950-1.2001.
The primary function of the uninterruptible power systems (UPS) covered by this Part
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.
Notes on regional differences in relevant clauses of GB 4943-2001 and IEC 60950-1.
2001 also apply.
This Part 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 any operator
accessible area. This Part specifies requirements to ensure safety for the operator and
layman who may come into contact with the equipment and, where specifically stated,
for the service person.
This Part 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 Part does not cover d.c. supplied electronic ballasts (IEC 60924 and IEC 60925),
UPS intended to be installed in separated electrical locations and UPS based on
rotating machines.
The relevant general and safety requirements for UPS installed in restricted access
locations are given in GB 7260.4; electromagnetic compatibility (EMC) requirements
and definitions are given in GB 7260.2.
1.2 Specific applications
Even if this Part does not cover all types of UPS, it may be taken as a guide for such
equipment. Requirements additional to those specified in this Part may be necessary
for specific applications, for example.

Summary	This Chinese standard relates to DC link energy storage device having an electronic uninterruptible power supplies. This standard refers to GB 4943-2001 and IEC 60950-1: 2001 related content. This standard includes an uninterruptible power supply (UPS) primary function is to ensure the continuity of AC power supply output. UPS also allows power to maintain the specified characteristics, thereby improving power quality. GB 4943-2001 and IEC 60950-1: 2001 relevant chapters on regional differences comments also apply. This standard applies to pre- installed in the operator access area, low-voltage distribution systems for mobile, stationary, fixed or embedded -mounted UPS.
