Freedom SW Installation Guide

Installing the Inverter/Charger

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 16. 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 10.

2.

Connect the grounding cable 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).
