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

Manual
7.3.2 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.
ð The device is connected to the power grid.
NOTE
An AC-side disconnection unit must be provided during the final installation stage. This disconnector mechan-
ism must be installed so that it can be accessed at any time without obstruction.
NOTE
If an external residual current circuit breaker is necessary due to the installation specification, a type A residual
current circuit breaker must be used.
If the type A is used, the insulation threshold must be set to greater than/equal to (≥) 200 kOhm in the "Para-
meters" menu [see [See section 9.4.1} Page 35]].
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.
1. Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficiently short.

Connect PV generator to device

7.4.1 Checking the PV generator for a ground fault
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death will result if the live connections are touched. When there is sunlight present on the PV
generator, there is DC voltage on the open ends of the DC cables.
1. Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
2. Avoid short circuits.
3. Do not connect any strings with a ground fault to the device.
NOTE
The threshold value from which the insulation monitor reports an error can be set in the "Parameters"
menu.
