SOP — EVSE Emergency-Stop & RCD Test, CN → LV Corridor

Verdict: This SOP verifies E-stop loop continuity and RCD trip function on a Wallbox Pulsar Plus (model family PLP1-0-2-2-7 / PLP1-M-2-2-7) single-phase AC EVSE at the Tradvolt Riga service facility in approximately 4 hours per unit (Steps 1–10), applying IEC 61851-1:2017, IEC 61008-1 (latest consolidated edition, 2012/AMD1:2024 cited as normative reference), IEC 62955:2018, and ISO 2859-1:1999 AQL Level II with AQL 1.0 for electrical safety. Evidence date: 2026-09-22. Limitation: duty rates and Indicative EUR cost slots below are pending fresh quotation per shipment; transit time of 28–38 days CN→Riga is indicative pending vessel schedule; the OEM service manual citation is a URL-confirmed model-family installation guide; calibration interval of 12 months is per Tradvolt internal procedure, no external standard cited.
