7.2.1 Connecting the inverter to the power grid
The power connection wires are connected on the right of the connection area (Figure 12 on page 23).
DANGER
Risk of fatal injury due to electric shock
Severe injury or death will result if the live connections are touched.
› Switch off all power sources to the inverter before you insert the grid power cable into the unit.
› Make sure that the device is isolated from the public power supply and the system power supply
before starting work.
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.
