Electrical connectionPage 22 Operating instructions KACO blueplanet 50.0 TL3 S/Basic/M/XLENENAuthorised electricianMaking the grid connection (4-core connection to TN-C system)ඣ Insert L1, L2, L3, PEN through the cable fitting into the AC connectionarea.1. Connect cables in accordance with the labels on the PCB terminals(Figure 27).2. Check for secure fit of all connected cables in accordance with thetightening torque (see Table 5 on page 19).3. Tighten the cable fitting.» The inverter is now connected to the power grid.Figure 27: 4-pole connectionNOTEAn 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 togreater than/equal to (≥) 200kOhm in the “Parameters” menu (section 8.3 on Page 43).For questions regarding the appropriate type, please contact the installer or our KACO new energycustomer service.NOTEWhen the line resistance is high, i.e. long cables on the grid side, the voltage at the grid terminals ofthe inverter will increase in feed-in mode. The inverter monitors this voltage. If this 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.7.4 Preparing the DC connection7.4.1 Configuring the DC connector (XL version)431 215512643 7Figure 28: Insert wires Figure 29: Slide insert into sleeve Figure 30: Check fasteningKey1 Wire for DC connection 5 Cable fitting2 Spring 6 Contact plug3 Insert 7 Coupling4 Sleeve
