Three-Phase Connection - Riello 5KVA Installation And Use Manual

Three-phase connection

1. (THREE-PHASE CONNECTION 8-10kVA): Use 3 cables of cross-section 6 mm
L3) and 2 with cross-section 10 mm
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
(THREE-PHASE CONNECTION 6.5kVA): Use 3 cables of cross-section 4 mm
L3) and 2 of cross-section 6 mm
because in bypass operation they have to carry all of the input current). For the output use 3 cables
of cross-section 6 mm
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 terminal B.
c - Connect the neutral wire to terminal 6.
d - Connect the wires of the phases to terminals 3, 4 and 5 (for L1 use red wire).
Output line
a - Connect the earth wire to terminal C.
b - Connect the neutral wire to terminal 8.
c - Connect the live wire to terminal 7.
By-pass line
a - Ensure that a jumper is connected on terminals 9 and 10, this is necessary for correct operation of the
UPS.
3. Tighten the terminals well, close the back-pack and secure it with the screws taken out earlier.
