Ground
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.
• It is recommended that 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.
