(*) This is the minimum recommended cable cross sectional area for the maximum AC
input current (see datasheet) using multi-core copper cables with three loaded conduc-
tors for installations in conduit in a thermally insulated wall (A2 method according to
IEC-60364-5-52).
The final cross section might be different if the installation method is another one, in any
case, it has to be calculated by the installer, taking into account the cable materials, the
conditions of installation and distances.
(**) This is the maximum cable cross sectional area accepted by the Main circuit breaker .
4- Use a phillip screwdriver in order to connect the electric terminals. The maximum
tightening torque is 5 Nm.
5- Follow the label under the circuit breaker, connect the cables to the left and right
terminal, the terminals of the middle must be free.
