Before you connect the inverter, disconnect the
AC and DC sides from all power sources and
secure them against being inadvertently switched
back on.
The connection of the PV generator and the grid connection
are established via PCB terminals in the inverter's connection

fi gure 5.5).

At the AC and DC connection terminals, the maximum con-
ductor cross-section that can be connected is 6 mm² (AC) or
10 mm² (DC). When wire sleeves are used, the cross-section
is reduced to 4 mm² (AC) or 6 mm² (DC). The strip-off
length is 12 mm (AC) or 15 mm (DC). A screwdriver (slotted,
3.5 mm) is to be used for the terminals in the inverter. Put
the screwdriver into the cut-out provided. Press the screw-
driver upwards slightly. Feed the cable into the spring termi-
nal. Put the screwdriver back into the original position.
Remove the screwdriver. The spring terminal is closed and
