Making the grid connection
AC connection plug configured correctly.

Engage the AC connector with the device
connector
1. Insert the AC connection plug into the device connector
on the device.
NOTE: The AC connection is secure when an audible
click is heard.
2. Lay the cables correctly and in accordance with the
following rules:
– Lay the cables around the device with a minimum
clearance of 20 cm
– Never lay cables over semiconductors (cooling bodies).
– Excessive bending force may negatively impact the
protection rating. Lay the cables with a bending radius of
at least 4 times the cable diameter.

The device is connected to the power grid.
NOTE
An AC-side disconnection unit must be provided during the final installation stage. This disconnector
mechanism 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
current circuit breaker must be used.
For questions regarding the appropriate type, please contact the installer or our KACO new energy
customer 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.
