• 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 (see table below). 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.

Your Inverter/Charger’s Nominal DC Input Voltage must match the voltage of your battery or batteries—12 Volts in most 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 that are isolated from the drive system to prevent possible
draining of the main battery.

Connect your Inverter/Charger to your batteries using the following procedures:
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.

• 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/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 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 displayed on the Inverter/Charger's nameplate. See diagrams below for proper fuse placement.
