connected to the AC output port. Both of the two PE cables must be securely connected.
• Make sure that all the grounding points on the enclosures are equipotential connected
when there are multiple inverters.
• To improve the corrosion resistance of the terminal, it is recommended to apply silica gel
or paint on the ground terminal after installing the PE cable.
• The PE cable should be prepared by customers.
