Battery Connection

Connect your Inverter to your batteries using the following procedures:

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

transformer 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’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 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 and battery terminals to approximately

3.5Newton-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 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 comply with national and local codes and ordinances.

•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 inches of the battery. The fuse’s rating must equal or exceed the Minimum DC Fuse Rating listed 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.

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.

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's two negative terminals to the battery's single negative terminal; run two 2/0 gauge cables from the Inverter's two positive terminals, through two UL-listed fuses and fuse blocks, or equivalent, (one on each cable), to the battery's single positive terminal. Use the equivalent of two 2/0 cables in all other connections within the battery system. Connection to Two DC Terminals: It is acceptable to use two cables to connect your battery to only one positive and one negative DC terminal, however, your Inverter will provide reduced output power. It doesn't make a difference which positive and negative terminal you choose for the connection because both positive terminals are internally bonded and both negative terminals are also internally bonded. In this connection you must run one positive cable through one user-supplied UL-listed fuse and fuse block.
