4-1. Connection the DC cable

source [ + ] is positive, [ - ] is negative. Reverse polarity connection can
blow the internal fuse and may damage the inverter permanently.
Figure 17. DC cable connection
Warning! Make sure that all the DC connections are tight
(torque to 9 – 10 ft-lbs, 11.7 – 13 Nm). Loose connections
could result in overheating and can be a potential hazard.
Warning! The recommended inline fuse should be installed
as close to the battery positive terminal as possible failure to
use a fuse on the “+” cable running between the inverter and
battery may cause damage to the cable / inverter and will
void warranty.
Also, only use high quality copper wire and keep the cable length short
which is a maximum of 3 - 6 feet.
