3-3-1. Connect the cables to the power input terminals on the front panel of 
the inverter. The red terminal is positive (+) and black terminal is 
negative (-). Insert the cables into the terminals and tighten screw to 
clamp the wires securely. 
WARNING! 
Make sure all the DC connections are tight (torque 
to 9 – 10 ft-lbs, 11.7 – 13 Nm). Loose connections 
could result overheat in a potential hazard. 
WARNING! 
The installation of a fuse must be on positive cable. 
Failure to place a fuse on “+” cables running between 
the inverter and battery may cause damage to the 
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.
