Battery Connection
Connect your Inverter/Charger to your batteries using the following procedures:
•Connect DC Wiring: Though your Inverter/Charger is a
its rated output capacity is limited by the length and gauge of the cabling run-
ning from the bat- tery 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 con- nection and to prevent excessive heating at this connection. Insufficient tightening of the terminals could void your warranty. See Specifications page 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
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.
Vehicular
Your Inverter/Charger’s Nominal DC Input Voltage must match the voltage of your battery or
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.

NOTE: Select models include two positive and two negative DC terminals. Using the same connection architecture illustrated in the diagrams, run two 2/0 gauge cables from the Inverter/Charger’s two negative terminals to the battery’s single negative terminal; run two 2/0 gauge cables from the Inverter/Charger’s two positive terminals, through two
