Introduction
EN 61800-5-2:2020 is a technical standard that focuses on the safety requirements of adjustable speed electrical power drive systems (PDS) which are used in various applications, including industrial and commercial sectors. This article provides an of this standard and its significance in ensuring the safe operation of such systems.
Scope and Applicability
The standard EN 61800-5-2:2020 primarily addresses the functional safety aspects of PDS. It provides guidelines and requirements for the design, development, integration, and validation of safety functions within these systems. The standard is applicable to all types of PDS, regardless of their power rating, voltage level, or operating conditions. It covers a wide range of technologies, including variable frequency drives (VFD), inverters, and servo motor drives.
Main Requirements
EN 61800-5-2:2020 specifies several important requirements for achieving functional safety in PDS. One key aspect is the identification and assessment of hazards associated with the operation of the system. This involves conducting a thorough analysis of possible risks and implementing necessary measures to mitigate them. The standard also emphasizes the need for safety-related control functions and provides guidelines for their implementation. Additionally, it outlines the process of verification and validation of safety functions to ensure their effectiveness.
Compliance and Benefits
Adhering to the requirements set forth by EN 61800-5-2:2020 offers several benefits. First and foremost, it enhances the safety of the system, protecting both the users and the equipment itself from potential hazards. Compliance with this standard also increases the reliability and performance of the PDS. Furthermore, manufacturers and suppliers who comply with EN 61800-5-2:2020 gain a competitive edge in the market as it demonstrates their commitment to delivering high-quality and safe products.
