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 in this Installation Guide. 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 DC grounding cable (No. 1/0 AWG or larger copper cable)
between the chassis ground point and the DC grounding point for your
system, usually the boat’s DC grounding bus.
3. Tighten the bolt to a torque of 3.5–3.8 ft-lbs (4.5–5.2 Nm).
