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 conduc-
tor cross-sections.

NOTE
When selecting installation material, please consider the suitability of the product to the mains
voltage (30.0-40.0 TL3, 60.0 TL3: 230/400 V. 48.0 TL3, 72.0 TL3: 277/480V).
NOTE
An AC-side disconnection unit must be provided during the fi nal installation stage. This disconnec-
tion unit must be installed so that it can be accessed at any time without obstruction.
If a residual current circuit breaker is necessary due to the installation specifi cation, a type A residual
current circuit breaker must be used.
For questions regarding the appropriate type, please contact the installer or our KACO new energy
customer service.
NOTE
If the cable impedance 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.
Make the grid connection (5 core connection, TN-S system)
1. Run L1, L2, L3, N through the included ferrite (60.0 TL3 only).
2. Connect the cables in accordance with the label on the PCB terminals
(Figure 20 on page 21).
3. Connect terminal "PE" to the equipotential bonding of your lightning
protection system using a 16 mm² wire.
4. Check that all connected cables are securely fi tted.
5. Tighten the cable fi tting.

Make the grid connection (4 core connection, TN-C system)
1. Fit the PE terminal (not supplied) to the hat rail. Note the cable
cross-sections.
2. L1, L2, L3 through the included ferrite (60.0 TL3 only).
3. Connect the cables in accordance with the label on the PCB terminals
(Figure 21 on page 21).
4. Check that all connected cables are securely fi tted.
