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. 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
warranty.
• Connect Ground: Using a 8 AWG (3.15 mm) 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 your Inverter/Charger's positive DC Terminal directly to
a UL-listed fuse(s) and fuse block(s) within 18 inches (450 mm) of the battery. The fuse's rating must equal or exceed the Minimum DC Fuse
Rating listed in your Inverter/Charger's nameplate. See diagrams below.
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.
Your Inverter/Charger's Nominal DC Input Voltage must match the voltage of your battery or batteries.
In 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 which are isolated from the drive system to prevent possible
draining of the main battery.
