Battery Connection Connect your Inverter/Charger to your batteries using the following procedures: • 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 ­(see table below). 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. 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.

The fuse's rating must equal or exceed the minimum DC fuse rating displayed on the Inverter/Charger's nameplate. See diagrams below for proper fuse placement. 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. Non-Vehicular or 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 that are isolated from the drive system to prevent possible draining of the main battery. 1 2 12 Volts 12 Volt Main Battery Connection 12 Volts 3 7 5 12 Volt Inverter/Charger 6 4 7 2 1 12 Volts 12 Volts 2 5 12 Volt Inverter/Charger 12 Volt Main and Auxiliary (House) Battery Connection (Isolated Parallel) 12 Volts 3 1 12 Volt Alternator 2 Vehicle Battery Ground 3 12 Volt Main Battery 4 12 Volt Auxiliary (House) Battery 5 UL-Listed Fuse & Fuse Block (mounted within 18 inches of the battery) 6 Battery Isolator 7 Large Diameter Cabling, Maximum 2/0 Gauge to Fit Terminals 10
