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/yellow 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 nut on the chassis
ground point bolt shown in Figure 9.
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.
For marine installations, refer to the applicable local code for
marine DC grounding detail.
3. Tighten the nut to a torque of 1.47–1.7 Nm.
