Earthing; Measuring The Insulation Resistance Of The Cabling - ABB PVS800-IS Hardware Manual

34 Electrical installation

Earthing

The PVS800-IS inverter station has a main earthing busbar for container earthing.
Connect the inverter station to the earthing busbar of the MV station. Construct an earthing
electrode for the MV substation according to the local regulations. Lead the copper connection
wire from the MV substation's earthing busbar to the main earthing busbar (MEB) of the
inverter station. The MEB of the inverter station is located on the wall near the exit door.
Check that the inverter station is properly connected to earth.
