DC Cabling

Definition DC cabling includes all of the cables and connectors between the batteries, the DC disconnect and over-current protection device, and the inverter/charger.

Type All installations require multi-strand insulated cables. The DC cables must be copper and must be rated 105 °C minimum.

Size and Length See Table 3 for required DC cable length, cable size and required fuse size for the Freedom SW 2000. Wire size is usually marked on the cables.

IMPORTANT: Using a smaller gauge cable or a longer cable may cause the inverter to shut down under heavy load.

Planning the Installation

DC Grounding

The inverter/charger DC (chassis) ground terminal needs to be connected to the vehicle chassis by a minimum No. 8 AWG copper conductor that is either insulated (green) wire rated 90 °C or bare copper.

Consult your local electrical codes and other applicable electrical standards
