AC connection
An AC bayonet connector on the underside of the
unit is used for the three-wire grid connection (L, N,
PE) of the Solar Inverter. The grid connection should
always be 1-phase. Feeding is single-phase via AC
terminal 2.
If several Solar Inverters are operated in parallel in
a 3-phase grid, AC terminal 2 of the unit must be
distributed uniformly among the grid phases L1, L2
and L3 to avoid unequal loading.

For cables with a sheath diameter between 16 and
20 mm adapt the cable gland accordingly. To do this,
cut out the inner section of the blue sealing ring.
2 Slide the cable gland and the plug housing onto
the cable.
3 Connect the cable ends to the plug terminals in
accordance with the pin assignment.
Tightening torque: 0.7 Nm.
CAUTION
Incorrect pin assignment may result in destruction of
the unit!
