Step 3: Connecting the Chassis Ground
The chassis ground lug is used to connect the chassis of the inverter to
your system’s chassis grounding point, as required by installation codes.
Use copper cable that is either bare or provided with green insulation. Do
not use the chassis ground lug for your AC output grounding wire.
To connect the chassis ground:
Refer to Figure 2-2.
1. Using the 1/4 inch slot screwdriver, loosen the screw on the chassis
ground lug.
2. Connect a No. 8 AWG copper cable between the inverter’s chassis
ground lug and the DC grounding point for your system.
In an RV or vehicle installation, this will usually be the vehicle
chassis or a dedicated chassis ground bus.
3. Tighten the screw to a torque of 6–7 lbf-in (0.68–0.79 Nm).
