Recommended conductor cross-sections and fuse protection of NYM cables for fi xed wiring according to
VDE 0100 part 430
For cable lengths up to 20 m, use the conductor cross-sections named in table 6. Longer cable lengths require larger
conductor cross-sections.

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 .
› Ensure that the conductor cross-sections are suffi ciently large or that the cable lengths are suffi -
ciently short.
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) only functions with a three-phase grid connection.
› Observe the following grid-type-specifi c connection requirements and the schematic view in sec-
tion 3.2.3 on page 9.

ACTIVITY
Cables on the AC screw terminal must be re-tightened at regular intervals using the necessary
tightening torque (see chapter 7.2 on page 21).
