To make the mains power and load connections,
follow the instructions below:
1. Install a magneto-thermal switch (
63A for 6 & 10kVA
versions, 125A for 15 and 20kVA versions
) with
intervention curve D upstream of the machine (4 poles
for three-phase versions, 2 poles for single-phase
versions).
2. The connection terminals to use for the input and output
lines are located on the backpanel. Unscrew the 4
screws located on the sides of the cover (one on each
side, see figure).
3. Remove the backpanel cover (see figure to the side).

(EARTH, N and L) for the input, and 3
cables with cross-section 6 mm
2
for the output (EARTH, N and L).
5. Connect the wires to the relative terminals, following exactly the instructions given below:
Input line
a - Make sure that the magneto-thermal switch upstream is open.
b - Connect the earth wire to screw A.
c - Connect the neutral wire to terminal 2.
d - Connect the live wire to terminal 1.
Output line
a - Connect the earth wire to screw B.
b - Connect the neutral wire to terminal 3.
c - Connect the live wire to terminal 4.
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
of this manual

6. Tighten the terminals well, close the backpanel cover and secure it with the screws taken out earlier.
The suggested tighten force is 1.2~1.6Nm.
