IEC 62477-2 defines safety requirements for power electronic converter systems (PECS) operating between 1000 V AC/1500 V DC and 36 kV AC/54 kV DC, focusing on risks such as electric shock, thermal hazards, and arc-faults. The standard covers testing and safety regulations for high-voltage industrial and renewable energy applications, building upon the foundational requirements of IEC 62477-1.

Q: Can I use IEC 62477-2 for e-mobility (EV chargers)?
A: No. That falls under IEC 61851 series or IEC 62477-1 alone. Part 2 is strictly for rail traction systems. IEC 62477-2 defines safety requirements for power electronic

• A Contractual Requirement: Large OEMs (e.g., Siemens, ABB, Tesla) mandate that sub-suppliers declare compliance with Part 2 in their Technical Construction File (TCF).
• An Insurance Prerequisite: Liability insurers often require a copy of the Declaration of Conformity referencing the specific PDF edition. Using an obsolete version (e.g., from 2014 instead of 2021) is grounds for claim denial after a fire or fatality.
• A Market Access Key: For China (CCC), Japan (PSE), or Brazil (INMETRO), local regulators compare your test report against the exact clauses in the official PDF.

• IEC 62477-1 – General safety for all power electronic converters.
• IEC 62477-2 – Modifies or adds requirements specifically for traction applications.

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.

3. Touch Current (Leakage Current) PDS units, especially those with long motor cables, generate high capacitive leakage currents. IEC 62477-2 provides specific pass/fail limits for touch current and dictates when you need a fixed permanent connection (hardwired) versus a pluggable connection.
