PREFACE
This Standard was prepared by the Standards Australia Committee EL-027, Power Electronics.
The objective of this Standard is to provide designers, manufacturers and purchasers with
generic requirements for electronic power equipment. This Standard applies where there is no
product specific Standard available.
This Standard is identical with, and has been reproduced from IEC 62103, Ed.1.0 (2003),
Electronic equipment for use in power installations.
Informative notes have been added in Clauses 5.2.11.1 and 9.2.
As this Standard is reproduced from an International Standard, the following applies:

INTRODUCTION
As the title indicates this International Standard applies where electronic equipment (EE) is to
be installed or is used in power installations. The term electronic equipment denotes
equipment which may contain information technology equipment as well as power electronic
equipment and non-electronic components. Electronic equipment may be designed and used
as stand-alone-equipment or as sub-assemblies built as cubicles, plug-in-units or assembled
printed circuit boards. However the EMC requirements are always to be fulfilled on the
apparatus or system level.
The term power installation as used in this standard denotes an installation with assembled
electrical and electronic equipment in a given location and designed for coordinated operation
and connected to an electricity supply system. Although the use of the installation is not
specified it is expected that the main purpose will be controlling, regulating and converting
electrical energy. In all cases in this standard a power installation is interacting with the
electricity supply system, either directly e.g. by means of control, regulating and protection

This standard mainly applies where electronic equipment is integrated into or is used in power
installations. As the standard is also concerned with the design and testing of electronic
equipment, the appropriate clauses within it apply in cases where no other applicable
specifications exist in individual product standards.
Beyond that the main intention of the standard is to stipulate minimum requirements for the
design and manufacture of electronic equipment, for protection against electric shock, for
testing and for the integration into systems for power installations. Right from the beginning
and reflecting the experiences of the experts it seems necessary to use minimum
requirements in order to achieve a certain technical level with respect to safety and reliability.
This is especially true where electronic equipment is assembled into power installations.
In all cases where more severe requirements are defined in individual product standards or
purchasing specifications they shall take precedence over the requirements of this standard.
This may be true for special safety related applications of electronic equipment or applications
under special environmental conditions.
In the other cases where a product standard does not meet the minimum requirements of this
standard and therefore prevents the direct use of electronic equipment designed and
manufactured fulfilling the requirements of those product standards additional means have to
be considered in power installations. One possibility is to influence the environmental
conditions in which the electronic equipment is operating so that they are compatible with the
requirements of this standard. This can be done by special casing or means of filtering for
example. The other possibility is to improve the electronic equipment so that it meets the
requirements of this standard.

1 Scope
This International Standard applies to the use of electronic equipment (EE) in power
installations where a uniform technical level with respect to of safety and reliability is
necessary required. This standard also applies to EE which are not covered by a specific
product standard.
This is a free 7 page sample. Access the full version at http://infostore.saiglobal.com.
This standard defines the minimum requirements for the design and manufacture of EE
connected to low-voltage (not exceeding 1 000 V a.c. or 1 500 V d.c.) mains supplies, for
protection against electric shock, for testing and its integration into systems for power
installations.
This standard does not cover the following applications: Electrical accessories and electrical
appliances for household and similar purposes, medical equipment, electric railway
equipment, data processing without control on systems and processes, public and private
non-industrial telecommunication and radio communication equipment and networks,
protection relays, residual-current-operated protective devices, uninterruptible power
supplies, lighting equipment and public charging equipment for electrical vehicles.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
References to international standards that are struck through in this clause are replaced by
references to Australian or Australian/New Zealand Standards that are listed immediately
thereafter and identified by shading. Any Australian or Australian/New Zealand Standard that
is identical to the International Standard it replaces is identified as such.
