The IEC 62477-2:2018 standard specifies safety requirements for power electronic converter systems (PECS) and equipment. It specifically focuses on high-voltage power electronic converters with rated system voltages from 1,000 V AC or 1,500 V DC up to 36 kV AC or 54 kV DC.

2. Protection Against Thermal Hazards (Clause 6)

• Temperature limits for accessible surfaces (e.g., ≤ 70°C for metal parts touched briefly).
• Special requirements for heat sinks inside sealed renewable converters (often operating at 60°C ambient).
• Fire enclosure requirements: Materials must meet V-0 or V-1 rating per IEC 60695-11-10.

• "Caution: Two independent energy sources" (for hybrid solar+storage inverters).
• AC and DC terminal polarity indicators.
• Wiring diagrams for multiple DC inputs (e.g., several PV strings).

Essentially, if your product converts, conditions, or controls DC power for industrial or commercial applications, you need to apply IEC 62477-2 in conjunction with Part 1.
