7.2.1 Connecting the inverter to the power grid
The grid connection cables are connected to the connection area on the right (see figure 14 on page 21).
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 fixed wiring according to VDE
0100 part 430
For cable lengths up to 20 m, use the conductor cross-sections specified in Table 3. Longer cable lengths require
larger conductor cross-sections.

The largest fusing allowed is a B35 automatic circuit breaker, even
if the cross-section of the cable that has been laid would allow a
larger fusing. Always follow the applicable regulations regarding
the cross section and the manner of laying the cable.

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-specific grid overvoltage limit value, the inverter switches off.

Ensure that the conductor cross-sections are sufficiently large or that the cable lengths are suffi-
ciently short.
