When tightening connections support the terminals to prevent twisting.
Phase terminals (marked R1, S1, T1 and R2, S2, T2) appear at the right-hand side of the module and mate with
busbar risers fitted to the mounting steelwork. Once the module is in place use M10 bolts with plain and

cable connection – see Figure 2–19.
DC link terminals ( and -) appear at the front of the module and are connected with M10 bolts
