DC Connectors

Battery Connection

Connect your Inverter to your batteries using the following procedures:

•Connect DC Wiring: Though your Inverter is a high-

efficiency trans- former 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 diam- eter cabling (maximum 2/0 gauge) to fit your Inverter’s DC Input terminals. Shorter and heavier gauge cabling reduces DC voltage drop and allows for maximum transfer of current. Your Inverter is capable of deliver- ing 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 and battery terminals to approximately 3.5 Newton-meters of torque to create an efficient connection and to prevent excessive heating at this connec- tion. Insufficient tightening of the terminals could void your warranty. See separate

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 model. All installations must com- ply with national and local codes and ordi- nances.

•Connect Fuse: NEC (National Electrical Code) article 551 requires that you connect all of your Inverter’s positive DC Terminals directly to a UL-listed fuse(s) within 18 inch- es of the battery. The fuse’s rating must equal or exceed the Minimum DC Fuse Rating list- ed in your Inverter’s specifications. See Specifications for fuse recommendations. See diagrams below for proper fuse placement.

WARNING! • Failure to properly ground your Inverter to a vehicle’s chassis or earth ground may result in a lethal electrical shock hazard.

•Never attempt to operate your Inverter 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’s Nominal DC Input Voltage must match the voltage of your battery or batteries—12 Volts in most vehicular applications.

In most vehicles, the Inverter will be connected to the main battery within your vehicle's electrical system. However, it is also possible to connect your Inverter to one or more dedicated auxiliary (house) batteries which are isolated from the drive system to prevent possible draining of the main battery.
