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