mechanical damage.
• The protective conductor has a cross-section ≥ 10 mm² Cu.
• A second protective conductor with the same cross-section is provided.
• The protective conductor of a multi-conductor cable has a cross-section ≥ 2.5 mm² Cu.
Protective conductor of the converter line supply cable
The protective conductor must be dimensioned in compliance with local installation rules.
• If each converter is individually protected, the protective conductor with the same cross-sec‐
tion must be routed in the same way as the line connection cable to the converter.
