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.
