connected to it are set to OFF. Otherwise, the high voltage produced by the solar inverter
may cause electric shocks.

point
Do not connect the neutral wire to the enclosure as a PE cable. Otherwise, electric shocks may
occur.
•
The PE point at the AC output port is used only as a PE equipotential point, and cannot
substitute for the PE point on the enclosure.
•
Silica gel or paint be applied around the ground terminal after the PE cable is connected.

It is recommended that the right ground point be used for grounding. The other ground
point is reserved.
