same material. If the materials are different, ensure that the conductor of the PE cable with a
proper cross-sectional area produces a conductance equivalent to that of the cable specified in the
table. The specifications of the PE cable are subject to this table or calculated according to IEC
60364-5-54.
4.2 Installing a PE Cable
• It is recommended that the PE cable of the solar inverter be connected to a nearby ground
point. Connect the PE points of all solar inverters in the same array to ensure equipotential
connections to PE cables.
• To enhance the corrosion resistance of a ground terminal, you are advised to apply silica gel
or paint on it after connecting the PE cable.
