• 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. Note: the unit's DC connectors may be either threaded
studs or butt splices, depending on the model.
Vehicular
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 which 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 without 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 shown
on your Inverter/Charger's nameplate. See diagrams below for proper fuse placement.
