  • Page 18 5.3 The connec�on of the ground line Good grounding is good for resis�ng surge voltage shock and improving EMI perfor- mance.Therefore, before connec�ng AC, DC and communica�on cables, you need to ground the cable firstly. For a single system, just ground the PE cable. For mul�ple machine systems, all PE cables of the inverter need to be connected to the same grounding copper platoon to ensure the equipoten�al connec�on.
