Preparation before wiring:
Connect the protective ground wire (PE)
Connect the inverter to the grounding bar through the protective earth (PE) to achieve
grounding protection.

Good grounding is good for resisting surge voltage surges and
improving EMI performance. Therefore, before connecting AC, DC,
and communication cables, you need to ground the cable first.
For a stand-alone system, simply ground the PE cable; for a
multi-machine system, connect all the PE cables of the inverter to
the same grounding copper bar to ensure equipotential bonding.

frequency: 50Hz)
The recommended specifications for the AC output switch are as follows:
AC connection steps:
1. The five wires (A, B, C, N, and PE wires) connected to the grid are passed through an
AC shield and then coiled to the O / U terminal.
