The AC power cords (tri-phase and single-phase) have to be screwed to the bottom terminals of the switch. Add adequate ferrules on power cord cable terminations. In total there are 6 terminals to attach wires, and only 5 of them are to be used. They are labeled (from left to right): L1, L2, L3, (blank), L0 and N. Each wire must be securely attached to the terminals of the power switch.
