Wall / envelope note
Wall / envelope note
Customer 2 mm vs supplier 0.5–1.5 — keep both on the board; avoid inventing a merged range.
380–400 V / 50 Hz nameplate class
380–400 V / 50 Hz nameplate class
Order-header plant supply is 400 V / 50 Hz / 3φ; supplier VFD/motor nameplate is 380 V / 50 Hz — treat as one IEC 380/400 V class, not two conflicting site voltages.

Key details
Note 1
Keep wall-to-2 mm / molds 25&27 beside supplier 9.5–25 / 0.5–1.5 — keep both visible; avoid merging.
Note 2
Tutorial + mold-change + wiring diagram are deliverables per order sheet.
