5.4 Connecting the PE cables
Connect the inverter to the equipotential bonding bar by using the
protective earth cable (PE) for grounding.
ATTENTION
Pole earthing not permissible!
• As the inverter is transformerless, the plus and minus poles
of the PV generator must NOT be earthed. Otherwise, the
inverter will malfunction. In the PV system, not all live metal
parts (e.g. PV module frames, PV frame, generator
connection box housing, inverter housing) require earthing.
Procedure
1. Remove the insulation of the cable. For outside use, cables of ≥
4mm² are recommended for earthing).
Note: L2 is 2 to 3 mm longer than L1
2. Crimp the cable to the ring terminal:
