Page 13THREE- PHASE CONNECTION1. (THREE-PHASE CONNECTION 9E10KI, 9E10KIXL): Use 2 cables of cross-section 4 mm2 (L2 and L3) and 3 with cross-section 10 mm2 (EARTH, N, L1) for the input (N.B.: L1 and N are of greater cross-section because in bypass operationthey have to carry all of the input current). For the output use 3 cables of cross-section 10 mm2 (EARTH, N and L).(THREE-PHASE CONNECTION 9E15KI, 9E15KIXL): Use 2 cables of cross-section 4 mm2 (L2 and L3) and 3 of cross-section 16 mm2 (EARTH, N, L1) for the input (N.B.: L1 and N are of greater cross-section because in bypass operationthey have to carry all of the input current). For the output use 3 cables of cross-section 16 mm2 (EARTH, N and L).(THREE-PHASE CONNECTION 9E20KI, 9E20KIXL): Use 2 cables of cross-section 6 mm2 (L2 and L3) and 3 of cross-section 25 mm2 (EARTH, N, L1) for the input (N.B.: L1 and N are of greater cross-section because in bypass operationthey have to carry all of the input current). For the output use 3 cables of cross-section 25 mm2 (EARTH, N and L).2. Connect the wires to the respective terminals, 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 wires of the phases to terminals 1, 2 and 3 (for L1 use red wire).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 section ofthis manualFig.3-6 10~20K three phase input terminal view3. 3. Tighten the terminals well, close the backpanel cover and secure it with the screws taken out earlier.4. For 10 to 15kVA the suggested tighten force is 1.2~1.6Nm. For 20kVA, the suggested tighten force is 2.5~3 Nm.
