The PE cable connected to the enclosure of the inverter cannot replace the PE cable
connected to the AC output port. Make sure that both of the two PE cables are securely
connected.
Make sure that all the grounding points on the enclosures are equipotentially connected
when there are multiple inverters.
To improve the corrosion resistance of the terminal, you are recommended to apply silica gel
or paint on the ground terminal after installing the PE cable.
Connect the PE cable first before installing the equipment. Disconnect the PE cable before
dismantling the equipment.
