NOTE
In order to avoid asymmetries in the grid, systems with multiple inverters should be designed so that
the inverters feed into the grid in diff ering phases.
› The dynamic grid support (FRT) is functional with a three-phase grid connection only.
› Observe the following grid-type-specifi c connection requirements and the schematic view in
section 3.2.2 on page 9.

Making the grid connection
↻ Use wires with 3 conductors (L1, N, PE) or 5 conductors (L1, L2, L3, N, PE).
(3-phase grid monitoring)
1. Unscrew the cable fi tting.
2. Remove the outer cladding of the AC cables.
3. Insert the AC leads through the cable fi tting into the connection area.
4. Strip the insulation from the AC cables.
5. Open the locks for the PCB terminals.
6. Connect wires in accordance with the labels on the PCB terminals
(Figure 13).
7. Close the locks for the PCB terminals.
8. Check that all connected cables are tightly seated.
9. Tighten the cable fi tting.
» The inverter is now connected to the power grid.
NOTE
An AC-side disconnection unit must be provided in the fi nal installation. This disconnection unit
must installed in such a manner that it can be accessed at any time without hindrance.
If a residual current circuit breaker is necessary due to the installation specifi cation, a type A AC/
DC-sensitive residual current circuit breaker must be used.
7.2.2 Connecting the PV generator
Connect the PV generator on the right of the connection area (see Figure 12 on page 23). Use the provided cable
fi ttings.
Solar plug connectors can be delivered as an option with the inverter.
