Full title and description

IEC 62103:2003 — Electronic equipment for use in power installations. This International Standard specifies minimum safety and reliability requirements for electronic equipment (EE) intended for use in power installations and for EE not covered by specific product standards. It addresses design, manufacture, protection against electric shock, testing and integration of EE connected to low-voltage mains (not exceeding 1 000 V a.c. or 1 500 V d.c.).

Abstract

IEC 62103:2003 establishes a uniform technical baseline for electronic equipment used in power installations. The document defines general safety requirements, test provisions and integration considerations for low-voltage electronic equipment in power distribution and transmission environments. It excludes certain product families (for example many household appliances, medical equipment, railway equipment and some telecom apparatus) and was intended to be used where no more specific product standard exists.

Scope

This standard applies to electronic equipment (EE) for use in power installations where a uniform technical level for safety and reliability is required. It covers EE connected to low-voltage mains supplies (rated up to 1 000 V a.c. or 1 500 V d.c.) and provides minimum requirements for design, manufacture, protection against electric shock, testing and system integration. The standard does not apply to some application areas covered by other standards, such as household appliances, most medical devices, railway equipment, certain telecom apparatus, some protection relays and other specifically regulated product categories.

Key topics and requirements

• General safety requirements for electronic equipment used in power installations.
• Design and construction principles to reduce risks of electric shock and related hazards.
• Requirements for testing and verification of electrical safety and reliable operation in power-installation environments.
• Integration and coordination requirements for equipment installed as part of power systems.
• Limits of application and explicit exclusions where product-specific standards take precedence.
• Minimum technical baseline for EE when no product-specific standard exists.

Typical use and users

IEC 62103 was used by manufacturers and designers of electronic equipment intended for power installations, system integrators, test laboratories, conformity assessment bodies and standards committees as a reference for minimum safety and reliability requirements. It served as a fallback/group safety reference for product committees developing more specific standards for power-electronics-related equipment.

Related standards

IEC 62103 has been superseded by IEC 62477-1:2012 (Safety requirements for power electronic converter systems and equipment — Part 1: General). Other commonly referenced standards for related topics include EMC and environmental testing series (for example IEC 61000 and IEC 60068 series) and product- or domain-specific safety standards where applicable.

FAQ

Q: What is this standard?

A: IEC 62103:2003 is an International Standard titled "Electronic equipment for use in power installations" that set minimum safety and reliability requirements for low-voltage electronic equipment used within power installations.

Q: What does it cover?

A: It covers design, manufacture, protection against electric shock, testing and integration of electronic equipment connected to mains supplies not exceeding 1 000 V a.c. or 1 500 V d.c., except for items explicitly excluded or covered by product-specific standards.

Q: Who typically uses it?

A: Manufacturers of power-installation electronic equipment, system integrators, test houses, conformity assessors and standards developers used the document as a general safety reference when no product-specific standard applied.

Q: Is it current or superseded?

A: IEC 62103:2003 is superseded. It was replaced by IEC 62477-1:2012; users should consult the appropriate edition of IEC 62477-1 (and any later updates) for current group safety requirements.

Q: Is it part of a series?

A: IEC 62103 itself was a standalone International Standard addressing a group safety topic; it has been incorporated into the IEC 62477 series, which addresses safety requirements for power electronic converter systems and equipment.

Q: What are the key keywords?

A: Electronic equipment, power installations, low-voltage, safety, electric shock, testing, integration, power electronics.
