(and its upcoming revisions, such as the 2025 version referenced by standard providers) is an international standard entitled "Safety requirements for power electronic converter systems and equipment - Part 2: Power electronic converter systems from 1 000 V AC or 1 500 V DC up to 36 kV AC or 54 kV DC".
Using unauthorized copies can jeopardize your company's quality management system (QMS) audits and product liability insurance. Iec 62477-2 Pdf
Ensuring the equipment can withstand transient voltage surges (lightning strikes or grid switching events) typical of MV grid connections. 4. Mechanical and Structural Hazards (and its upcoming revisions, such as the 2025
Essentially, if your product converts, conditions, or controls DC power for industrial or commercial applications, you need to apply in conjunction with Part 1 . The document lists strict minimum physical distance values
