Battery Connection
• 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 gauge) to fit your Inverter/Charger’s DC
Input terminals. 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 175% of its rated continuous wattage output
for brief periods of time. See Specifications page 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 3.5
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. See page 2A for battery
wiring recommendations.
• Connect Ground: Using a #8 AWG wire or larger directly connect the Main Ground Lug to earth
ground. See the Feature Identification 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 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 listed in your
Inverter/Charger’s specifications. See Specifications for fuse and fuse block recommendations. See
diagrams below for proper fuse placement.
Connect your Inverter/Charger to your batteries using the following procedures:
DC Connectors
Battery Configuration
You may connect one or more batteries to your Inverter/Charger in either of the following
configurations.
Parallel connection: The voltage of each connected battery must match the Inverter/Charger's
Nominal DC Input Voltage (12V).
Series connection: The total voltage of all connected batteries must match the Inverter/Charger's
Nominal DC Input Voltage (12V). Example: 6V + 6V = 12V.

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.
