For installations that are stationary or in vessels that have no grounded frame, measure and use
all lengths of cable that connect the battery or battery bank to the inverter. Measure from battery
positive (+) to inverter positive (+), then add battery negative (-) to inverter negative (-). Use this
Total Cable Length to determine the correct cable gauge in table in “Appendix A”.

Total Cable Length for Home and Vessel Use
Many inverter installations are in 12V negative-ground vehicles. It is possible to use the vehicle
frame as the part of the negative (-) conductor back to the battery or battery bank. To determine
the Total Cable Length in this case, add all cable lengths. Do not include the vehicle chassis.
If installing in vehicle, ground inverter to chassis. Do not ground inverter to negative terminal.
