For the 800 VA and 1200 VA inverters:
For these inverters the earth wire from the chassis can be either connected to FJ1 (neutral
floating) or to FJ2 (neutral connected to earth/chassis). The labels FJ1 and FJ2 are printed on the
circuit board. The default position is FJ1, i.e. neutral is floating.
Appendix B
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.
