@Raz or should just the single L wire be connected to EITHER l1, l2 OR l3

Mr. Anderson
March 1, 2025

No, for single-phase Steamtec AIO (3KW, 4KW, 215~240V), the connection should be made to the designated terminals for single-phase wiring. L1, L2, and L3 are used for three-phase connections, so they should not be interconnected for a single-phase setup. Instead, follow the wiring diagram for single-phase installation.
