Connect Pv Generator To Device - Kaco blueplanet 3.0 TL3 M2 WM OD IIG0 Operating Instructions Manual

7.4.2 Make the grid connection
Make the grid connection
↻ AC connection plug configured correctly.
1 Insert the AC connection plug into the device connector on the device.
ð 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 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.
