Make the grid connection

4-core connection, TN-C system
↻ Grid connection is prepared.
1 Connect lines in accordance with the labels on the name plate on the screw ter-
minal [ T_45/ 10 Nm].
2 Check secure fit of all connected cables.
3 Tighten the cable fittings [ W_66 /
» The device is connected to the power grid.
NOTE
An AC-side disconnection unit must be provided during the final installation stage. This disconnecter mech-
anism must be installed so that it can be accessed at any time without obstruction.
NOTE
If a residual current circuit breaker is necessary due to the installation specification, a type A residual cur-
rent circuit breaker must be used.
If the type A is used, the insulation threshold must be set to greater than/equal to (≥) 200kOhm in the
"Parameters" menu Menu.
For questions regarding the appropriate type, please contact the installer or our KACO new energy cus-
tomer service.
NOTE
When the line resistance is high, i.e. long cables on the grid side, the voltage at the grid terminals of the
device will increase in feed-in mode. If the voltage exceeds the country-specific grid overvoltage limit
value, the device switches off.
› Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficiently
short.
