Safety requirements for power electronic converter systems and equipment - Part 1: General
IEC 62477-1:2022 applies to power electronic converter systems (PECS), any specified accessories, and their components for electronic power conversion and electronic power switching, including the means for their control, protection, monitoring and measurement, such as with the main purpose of converting electric power, with rated system voltages not exceeding 1 000 V AC or 1 500 V DC. This document also applies to PECS which intentionally emit or receive radio waves for the purpose of radio communication. This document can also be used as a reference standard for product committees producing product standards for: - adjustable speed electric power drive systems (PDS); - standalone uninterruptible power systems (UPS); - low voltage - stabilized DC power supplies; - bidirectional power converters. For PECS and their specified accessories for which no product standard exists, this document provides minimum requirements for safety aspects. This document has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems for solar, wind, tidal, wave, fuel cell or similar energy sources. According to IEC Guide 104, one of the responsibilities of technical committees is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of their product standards. Guidance for use of this group safety publication for product committees is given in Annex S. This document - establishes a common terminology for safety aspects relating to PECS, - establishes minimum requirements for the coordination of safety aspects of interrelated parts within a PECS, - establishes a common basis for minimum safety requirements for the PECS portion of products that contain PECS, - specifies requirements to reduce risks of fire, electric shock, thermal, energy and mechanical hazards, during use and operation and, where specifically stated, during service and maintenance, and - specifies minimum requirements to reduce risks with respect to PECS designed as pluggable and permanently connected equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the PECS in the manner prescribed by the manufacturer. This document does not cover - telecommunications apparatus other than power supplies to such apparatus, - functional safety aspects as covered by, for example, IEC 61508 (all parts), and - electrical equipment and systems for railways applications and electr

Overview
EN IEC 62477-1:2023 (identical to IEC 62477-1:2022 / EN IEC 62477-1:2023) defines safety requirements for power electronic converter systems and equipment (PECS). It applies to PECS, specified accessories and components used for electronic power conversion and switching - including control, protection, monitoring and measurement means - with rated system voltages up to 1 000 V AC or 1 500 V DC. The standard also covers PECS that intentionally emit or receive radio waves for communication and serves as a group safety publication under IEC Guide 104 for converters used with solar, wind, tidal, wave, fuel cell and similar energy sources.
Key topics and technical requirements
- Scope and terminology: establishes a common vocabulary for safety aspects related to PECS, ensuring consistent interpretation across product standards and committees.
- Minimum safety requirements: sets baseline requirements for the PECS portion of products where no dedicated product standard exists.
- Hazard reduction: specifies measures to reduce risks of electric shock, fire, thermal, energy and mechanical hazards during normal operation and, where stated, during service and maintenance.
- Coordination of interrelated parts: requires minimum design coordination between interconnected units and independent units within PECS to ensure overall system safety.
- Installation types: addresses requirements for both pluggable and permanently connected equipment.
- Radio functionality: includes PECS that intentionally use radio waves (e.g., for telemetry or control).
- Guidance for product committees: Annex S offers direction for using this group safety publication when preparing product-specific standards.
Practical applications
EN IEC 62477-1:2023 is applicable to designers, manufacturers and integrators of:
- Adjustable speed electric power drive systems (PDS)
- Standalone uninterruptible power systems (UPS)
- Stabilized low-voltage DC power supplies
- Bidirectional power converters
- Renewable-energy converter systems (solar, wind, tidal, wave, fuel cell)
It is used to establish minimum safety requirements when no product-specific standard exists, to harmonize safety clauses across product families, and to support risk assessment and compliance activities.
Who should use this standard
- Product committees and standards developers
- Electrical and safety engineers designing PECS and accessories
- OEMs and system integrators of power converters
- Test laboratories and compliance officers verifying low-voltage converter safety
Related standards
Referenced or related documents include IEC Guide 104 (group safety publications), IEC 61508 (functional safety - excluded from this standard), IEC 62109-1 (power converters for photovoltaic systems), and insulation/flammability standards such as IEC 60664-1 and IEC fire-testing standards. These references support coordinated application of safety, insulation coordination and testing practices.

Frequently Asked Questions
EN IEC 62477-1:2023 is a standard published by CLC. Its full title is "Safety requirements for power electronic converter systems and equipment - Part 1: General". This standard covers: IEC 62477-1:2022 applies to power electronic converter systems (PECS), any specified accessories, and their components for electronic power conversion and electronic power switching, including the means for their control, protection, monitoring and measurement, such as with the main purpose of converting electric power, with rated system voltages not exceeding 1 000 V AC or 1 500 V DC. This document also applies to PECS which intentionally emit or receive radio waves for the purpose of radio communication. This document can also be used as a reference standard for product committees producing product standards for: - adjustable speed electric power drive systems (PDS); - standalone uninterruptible power systems (UPS); - low voltage - stabilized DC power supplies; - bidirectional power converters. For PECS and their specified accessories for which no product standard exists, this document provides minimum requirements for safety aspects. This document has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems for solar, wind, tidal, wave, fuel cell or similar energy sources. According to IEC Guide 104, one of the responsibilities of technical committees is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of their product standards. Guidance for use of this group safety publication for product committees is given in Annex S. This document - establishes a common terminology for safety aspects relating to PECS, - establishes minimum requirements for the coordination of safety aspects of interrelated parts within a PECS, - establishes a common basis for minimum safety requirements for the PECS portion of products that contain PECS, - specifies requirements to reduce risks of fire, electric shock, thermal, energy and mechanical hazards, during use and operation and, where specifically stated, during service and maintenance, and - specifies minimum requirements to reduce risks with respect to PECS designed as pluggable and permanently connected equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the PECS in the manner prescribed by the manufacturer. This document does not cover - telecommunications apparatus other than power supplies to such apparatus, - functional safety aspects as covered by, for example, IEC 61508 (all parts), and - electrical equipment and systems for railways applications and electr
