• Connect DC Wiring: Though your Inverter/Charger 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
shortest length and largest diameter cabling (maximum 2/0 gauge) to fit your Inverter/Charger’s DC Input
terminals. Shorter and heavier gauge cabling reduces DC voltage drop and allows for maximum transfer of
current. Your Inverter/Charger is capable of delivering peak wattage at up to 200% of its rated continuous
wattage output for brief periods of time. See Specifications page for details. Heavier gauge cabling should be
used when continuously operating heavy draw equipment under these conditions. Tighten your
Inverter/Charger and battery terminals to approximately 3.5 Newton-meters of torque to create an efficient
connection and to prevent excessive heating at this connection. Insufficient tightening of the terminals could
void your warranty. See Specifications Sheet for Minimum Recommended Cable Sizing Chart.
• Connect Ground: Using a #8 AWG wire or larger directly connect the Main Ground Lug to the vehicle’s chassis or earth ground. See
the Feature Identification section to locate the Main Ground Lug on your specific Inverter/Charger model. All installations must comply
with national and local codes and ordinances.
• Connect Fuse: NEC (National Electrical Code) article 551 requires that you connect all of your Inverter/Charger’s positive DC Terminals
directly to a UL-listed fuse(s) and fuse block(s) within 18 inches of the battery. The fuse’s rating must equal or exceed the Minimum DC
Fuse Rating listed in your Inverter/Charger’s specifications. See Specifications for fuse and fuse block recommendations. See diagrams
below for proper fuse placement.
Vehicular
Your Inverter/Charger’s Nominal DC Input Voltage must match the voltage of your battery or batteries—12 Volts in most vehicular
applications.
It is possible to connect your Inverter/Charger to the main battery within your vehicle’s electrical system. In most vehicles, the Inverter/
Charger will be connected to one or more dedicated auxiliary (house) batteries which are isolated from the drive system to prevent possible
draining of the main battery.

Connect your Inverter/Charger to your batteries using the following procedures:
WARNING! • Failure to properly ground your Inverter/Charger to a vehicle’s chassis or earth
ground may result in a lethal electrical shock hazard.
• Never attempt to operate your Inverter/Charger by connecting it directly to output from an
alternator rather than a battery or battery bank.
• Observe proper polarity with all DC connections.
