The left block is dedicated to tri-phase lines, so the three contacts are used. The block on the right side is dedicated to single-phase lines, so only two contacts form the total of three are used. 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. Label on Switch L1 L2 Wire Phase Phase Power Cord Tri-phase Tri-phase 24 Chapter 5 Connect the power cables ENWW
