(SINGLE-PHASE CONNECTION 9E10KI, 9E10KIXL): use 3 cables of cross-section 10 mm2 (EARTH, N and L) for theinput, and 3 cables of cross-section 10 mm2 for the output(EARTH, N and L).(SINGLE-PHASE CONNECTION 9E15KI, 9E15KIXL): use 3 cables of cross-section 16 mm2 (EARTH, N and L) for theinput, and 3 cables of cross-section 16 mm2 for the output(EARTH, N and L).(SINGLE-PHASE CONNECTION 9E20KI, 9E20KIXL): use 3 cables of cross-section 25 mm2 (EARTH, N and L) for theinput, and 3 cables of cross-section 25 mm2 for the output(EARTH, N and L).5. Short-circuit the input terminals (1, 2 and 3) with the jumper provided in the accessories kit. Connect the wires to the respectiveterminals, following exactly the instructions below:Input linea - Ensure that the upstream magneto-thermal switch is open.b - Connect the earth wire to screw A.c - Connect the neutral wire to terminal 4.d - Connect the live wire to terminal 1.Output linea - Connect the earth wire to screw B.b - Connect the neutral wire to terminal 5.c - Connect the live wire to terminal 6.R.E.P.O.a - The REPO connection (between terminal 5 and 6) is normally open. For more information please refer to the REPO sectionof this manualFig.3-5 10~20K single phase input terminal view6. Tighten the terminals well, close the backpanel cover and secure it with the screws taken out earlier.For 10 to 15kVA the suggested tighten force is 1.2~1.6Nm. For 20kVA, the suggested tighten force is 2.5~3 Nm.JUMPER
