NOTE
When the line resistance is high (i.e. long grid-side cables), the voltage at the grid terminals of the
inverter will increase during feed-in to the grid. The inverter monitors this voltage. If it exceeds the
country-specifi c grid overvoltage limit value, the inverter switches off .

Making the grid connection
↻ Use cables with three wires (L1, N, PE).
1. Loosen cable fi tting for AC connection.
2. Remove the outer cladding of the AC cables.
3. Insert the AC leads through the cable fi tting into the connection area. (See Figure 13 on page 20)
4. Strip the insulation from the AC cables.
5. Guide the AC leads through the ferrite cores.
6. Wrap the AC leads once around the ferrite cores. (See Figure 14 on page 20)
