AC line connection
• Pass the AC cables through the cable glands (11) on the AC panel. The lenght of phase cables on the
internal side of wiring box need to be about 300 mm (cable lug included).
• Fix the R, S and T cable lugs to the AC connection busbars (27), paying attention to the correspondence
of the phases with the labels, using the washers and the M10 nuts pre-installed on the busbar as shown
in the following diagram:
1 = cable lug

ATTENTION – A In case of a wrong phase sequence the inverter will not connect to the grid and
it will provide an error state.
ATTENTION – A The cable lugs must be installed with a tightening torque of 25Nm.
• Re-install the AC protective shield (23) by using the M5 screw and the M5 nut previously removed with a
tightening torque of 3 Nm.
• Check the tightness of the AC cable glands (11) (5 Nm for single core AC cable gland M40 / 18 Nm for
multi core AC cable gland M63) and, if used, protective earth cable gland (12) (5 Nm for PE cable gland
M32) at the end of the installation.
ATTENTION – A In case of the AC cable glands (11) was accidentally removed during the cable
routing phase, it will needed to assure the correct tightness of the lock nut of the cable gland
to the inverter chassis with a tightening torque of 8.0 Nm (for each cable gland).
