Making DC Wiring Connections

Your cable should be as short as possible (ideally use factory cables) and large enough to
handle the required current in accordance with the electrical codes or the application. If
cables are not an adequate gauge (too narrow) or too long, it will decrease the inverter
performance such as poor surge capability, frequent low input voltage warnings, and
shutdowns. UVP warning will occur due to DC voltage drop across the cables from the
inverter to the batteries. The longer or narrower the cables, the greater the voltage drop.
Increasing your DC cable size will help improve the situation.
Choose a location that is dry, ventilated, and safe from flammable gases or liquids.
Warning
The installation of a fuse must be on the positive DC cable. Failure to place a
fuse on "+" cables running between the inverter and battery may cause
damage to the inverter and will void warranty.
Other equipment connected to the battery may require separate fuses. Follow the
manufacturer instructions.
