5.3. The Connection of the Ground Line
Good grounding is essential for resisting to surge voltage shock and improving EMI performance.
Therefore, before connecting AC, DC, and communication cables, you need to ground the cable firstly.
For a single system, just ground the PE cable. But, for multiple machine systems, all PE cables of the
inverter need to be connected to the same grounding copper platoon to ensure the equipotential
connection. The installation of the shell ground wire is shown in Figure 20.
