DC Grounding
The Chassis Ground point on the inverter/charger is used to connect the chassis of
the inverter/charger to your system’s DC grounding point, as required by
regulations for some installations. Use copper wire that is either bare or provided
with green insulation.
The grounding guideline given below assumes you are using the code-compliant
DC supply cable and fuse sizes indicated on page 14. If you are using different
sizes, refer to the applicable code for DC grounding detail.
To connect the chassis ground:
1. Using the appropriate wrench, loosen the bolt on the chassis ground point
shown in Figure 8.
2. Connect the grounding cable (see page 25) between the chassis ground point
and the DC grounding point for your system.
In an RV or vehicle installation, the DC grounding point will usually be the
vehicle chassis or a dedicated chassis ground bus.
3. Tighten the screw to a torque of 1.0–1.25 ft-lbs (1.47–1.7 Nm).
