Three-phase grid connection
PE N L3 L2 L1
Always use sufficiently dimensioned cable
cross-sections to prevent a significant incre-
ase of the grid impedance between the
service distribution system and the Solar
Inverter. The capacity of the AC terminals is

0.5 mm
to 6 mm
for rigid cables, and 0.5

mm
to 10 mm
for flexible cables. If the
grid impedance is high, i. e. due to relati-
vely long or thin cables, the voltage at the
grid terminal is increased during injection.
If the terminal voltage exceeds the admissi-
ble value, the Solar Inverter is disconnected
from the grid. If the power grid is weak
and the PV output is high, individual Solar

Inverters may repeatedly switch on and off.
Carry out the following steps carefully:
· Prior to inserting the power cable into
the device, make sure it is de-energised.
