Three-phase connection
1. (THREE-PHASE CONNECTION 9E10KI, 9E10KIXL): Use 2 cables of
cross-section 4 mm
(EARTH, N, L1) for the input (N.B.: L1 and N are of greater cross-
section because in bypass operation they have to carry all of the
input current). For the output use 3 cables of cross-section 10 mm
(EARTH, N and L).
(THREE-PHASE CONNECTION 9E15KI, 9E15KIXL): Use 2 cables of
cross-section 4 mm
(EARTH, N, L1) for the input (N.B.: L1 and N are of greater cross-
section because in bypass operation they have to carry all of the
input current). For the output use 3 cables of cross-section 16 mm
(EARTH, N and L).
(THREE-PHASE CONNECTION 9E20KI, 9E20KIXL): Use 2 cables of
cross-section 6 mm
(EARTH, N, L1) for the input (N.B.: L1 and N are of greater cross-
section because in bypass operation they have to carry all of the
input current). For the output use 3 cables of cross-section 25 mm
(EARTH, N and L).
2. Connect the wires to the respective terminals, following exactly the
instructions below:
Input line
a - 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 line
a - 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.
