Chassis to ground connection
Wire size for connecting the inverter chassis to ground:
The earth conductor from the earth lug on the chassis to ground should have at least half the cross-section of the conductors used for the battery connection.
The maximum conductor size that fits the earth lug is 25 mm². Use the table below to find the correct cross-section for the earth conductor.
The AC output is isolated from the DC input and the chassis . Local regulations may require a true neutral. For instructions, see appendix Installation information neutral to ground connection.
