DC Connectors

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 AWG (6.544 mm)) to fit your Inverter/Charger’s DC connectors. 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 above its rated continuous wattage output for brief periods of time. See the Specifications

section 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

3.5Newton-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 the Specifications section for battery wiring recommendations.

•Connect Ground: Use an 8 AWG (3.264 mm) wire or larger to connect the Main Ground Lug to earth ground. See the Features section to locate the Main Ground Lug on your Inverter/Charger. 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 connectors directly to a UL-listed fuse(s) and fuse block(s) within 18 inches (45.72 cm) of the battery. The minimum rating of the DC fuse is listed in the Specifications section. See the following battery configuration diagrams for proper fuse placement.

WARNING!

• Failure to properly ground your Inverter/Charger 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.

Battery Configuration

You may connect one or more batteries to your Inverter/Charger in either of the following configurations.

1Parallel Connection: The voltage of each connected battery must match the Inverter/Charger's Nominal DC Input Voltage (12 V).

2Series Connection: The total voltage of all connected batteries must match the Inverter/Charger's

Nominal DC Input Voltage (12 V). Example: 6 V + 6 V = 12 V.
