Units without optional cabling panels (no +H381 or +H383)
In units without optional cabling panels (H381/+H383 not selected), it is
possible to use the maximum cable size (4 × (3 × 240) mm2 or 4 × [3 × 500 AWG])
only with special cable lugs and additional insulation. For more information, contact
your local ABB representative.
