Installing the Inverter/Charger
This guide for use by qualified installers only.
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 13. 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 7.
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).
