Installation Instructions KACO blueplanet 32.0 TL3 / 40.0 TL3 / 50.0 TL3 Page 19
Recommended conductor cross-sections and fuse protection of NYM cables for fi xed wiring according to VDE 0100
part 430
For cable lengths up to 20m, use the specifi ed conductor cross-sections. Longer cable lengths require larger conductor
cross-sections.
Equipment types Conductor cross-sec-
tion Fuse protection: gL safety fuses
32.0 - 40.0 TL3 5 AWG / 16 mm² 63 A
50.0 TL3 2 AWG / 35 mm² 100 A

NOTE
When selecting installation material, please consider the suitability of the product to the mains voltage.
NOTICE
The installation must be performed in accordance with NFPA 70 and Canadian electrician code part I and
additional local requirements.
NOTICE
Use copper conductors only.
NOTICE
When the line resistance is high (i.e. long grid-side cables), the voltage at the grid terminals of the inverter
will increase during feed-in to the grid. The inverter monitors this voltage. If it exceeds the country-specifi c
grid overvoltage limit value, the inverter switches off .
› Ensure that the conductor cross-sections are suffi ciently large or that the cable lengths are suffi ciently
short.
Prepare the grid connection
↻
Drill a hole for the AC leads into the connection board.
1. Remove the outer cladding of the AC leads.
2. Insert the AC leads through the hole into the connection area through the conduit pipe.
3. Strip the insulation from the AC leads.
4. Open the locks of the PCB terminals.
5. Connect the leads according to the labels on the PCB terminals.
6. Close the locks of the PCB terminals.
7. Check that all connected leads are tightly seated.
8. The inverter is now connected to the power grid.
Making the grid connection
1. Route L1, L2 and L3 through the enclosed ferrite clip.
2. Connect the cables in accordance with the label on the PCB terminals
(Figure 12 on page 19).
3. Connect the ground and N-terminal to the specifi ed connection terminal.
Note the cable cross-sections.
4. Check that all connected cables are securely fi tted.
5. Tighten the cable fi tting.
