Battery Connection
WARNING!
Make sure the inverter power switch is in the OFF position,
connect with included DC Wiring to the positive and negative
terminals. Though your Inverter is a high-efficiency converter
of electricity, its rated output capacity is limited by the length
and gauge of the cabling running from the battery to the unit.
Use the included cabling or the shortest length and largest
diameter cabling (see the Recommended Cabling and Fusing
Chart below) with ring terminals to fit your Inverter’s DC Input
terminals. Shorter and heavier gauge cabling reduces DC voltage
drop and allows for maximum transfer of current. Your Inverter
is capable of delivering peak wattage at up to 200% of its rated
continuous wattage output for brief periods of time. Heavier
gauge cabling should be used when continuously operating
heavy-draw equipment under these conditions. To protect
the battery system, it is also recommended to install a user-
supplied UL-rated ANL fuse and fuse block 7-18 inches from the
battery bank’s positive terminal connection. The inverter has its
own internal DC fusing to protect against short circuits at the
inverter’s output.
