The inverter monitors this voltage. If it exceeds thecountry-specific grid overvoltage limit value, the inverter switches off.› Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficientlyshort.Connect the power supply Use cables with 5 wires (L1, L2, L3, N, PE).1. Unscrew the cable fitting.2. Remove the outer cladding of the AC cables.3. Insert the AC cables through the cable fitting into the connection area.4. Strip the insulation from the AC cables.5. Open the locks for the PCB terminals.6. Connect the cables in accordance with the label on the PCB terminals(Figure 14 on page 18).7. Close the locks for the PCB terminals.8. Check secure fit of all connected cables.9. Tighten the cable fitting.» The inverter is now connected to the power grid.PE NBUL2BKL1BNGNYEL3GYFigure 14: AC connection terminalsNOTEAn AC-side disconnection unit must be provided during the final installation stage. This cut-offmechanism must be installed so that it can be accessed at any time without obstruction.NOTEIf a residual current circuit breaker is necessary due to the installation specification, a type A residualcurrent circuit breaker must be used.If the type A is used, the insulation threshold must be set to greater than/equal to (≥) 200kOhm inthe “Parameters” menu (section 8.3 on Page 39).For questions regarding the appropriate type, please contact your installer or our KACO new energycustomer service.
