• Install the R, S and T phases and MID BULK cable (coming
from the wiring box) to the respective AC interface connec-
tion point (25) inside the power module, paying attention to
the correspondence of the phases with the labels, using the
M6 bolts (for phases) and the M5 bolt (for MID BULK) sup-
plied in the power module installation kit:
In case of a wrong phase sequence the inverter
will not connect to the grid and it will provide an
error state.
The cable lugs must be installed with a recom-
mended torque of:
M6 bolt (R,S,T phases) = 4Nm (3 ft-lb)
M5 bolt (MID BULK) = 3Nm (2.2 ft-lb) .
• Install the protective earth cable lug to the protection earth
point interface cable
(26)
situated on the internal bottom
side of power module (01) , using the washers and bolt sup-
plied in the power module installation kit, as shown in the fol-
lowing picture:
