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 DC Connectors
warranty.
Maximum Recommended DC Cable Length	Maximum Distance From Battery to Inverter/Charger
			Wire Gauge (AWG)
	Output	6	4	2	0	00 (2/0)
	750W	10 ft	16 ft	26 ft	42 ft	52 ft
	1250W	Do Not Use	Do Not Use	16 ft	25 ft	31 ft
	2000W	Do Not Use	Do Not Use	Do Not Use	Do Not Use	20 ft

Warning: Do not use a wire gauge smaller than 6 AWG.

•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 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.
