Figure 2.17 Cables with different conductors (from top to bottom):
multi-strand, fine-strand and extra fine-strand
The inverter may only be connected to a three-phase utility
grid.
Strip off the insulation of all four AC cable conductors. The
protective conductor (PE) must be longer than the grid wires.
1. Verify that the nominal voltage of the inverter matches
the grid voltage.
2. Ensure that the main circuit breaker is released, and
take precautions to prevent reconnection.
3. Open the front cover.
4. Insert the cable through the AC cable gland to the
terminal block.
5. Connect the three grid wires (L1, L2, L3) and the
grounding conductor (PE) to the terminal block with the
respective markings. The grounding conductor is
marked with the symbol shown in figure 2.17.
6. Optional: Make an extra PE connection at the
secondary PE grounding points using the external
device grounding bolt delivered with the inverter. See
figure 5.2.
7. All conductors must be properly attached with the
correct tool (screwdriver bit, length min. 50 mm) and
correct torque, see Section 5.4, page 45.

LEAKAGE CURRENT HAZARD
Insufficient grounding of the inverter can lead to serious
injuries or lethal injuries.
• Ensure the correct grounding of the devices by a
certified electrical installer.
