• Connect DC Wiring:
You must run positive
cable(s) through user-sup-
plied UL-listed fuse(s)
and fuse block(s) of the
proper size.
See Specifications page for Minimum Recommended Cable Sizing
Chart. An excellent source of cables is battery jumper cables. Output
performance will decrease if you use only one jumper cable.
Although your Inverter 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 00 gauge) to fit
your Inverter’s DC Input terminals. Shorter
and heavier gauge cabling reduces DC volt-
age drop and allows for maximum transfer
of current. Your Inverter is capable of deliv-
ering peak wattage at up to 200% of its rated
continuous wattage output instantaneously.
See Specifications page for details. Heavier
gauge cabling should be used when continu-
ously operating heavy draw equipment under
these conditions. Tighten your Inverter and
battery terminals to approximately 3.5
Newton-meters (2.58 foot lbs.) 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 wire
or larger, directly connect the Main Ground
Lug to the vehicle's chassis ground or earth
ground. See Feature Identification section to
locate Main Ground Lug. All installations
must comply with national and local codes
and ordinances.
• Connect Fuse:
In addition to the
protection provided by the Inverter’s
internal fuses, NEC article 551 requires that
you connect your Inverter’s positive DC
Terminal(s) directly to a UL-listed fuse(s)
and fuse block(s) within 18 inches of the
battery. See diagrams below for proper fuse
placement.
Battery Connection
Vehicular
Your Inverter’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 to the main battery within your vehicle’s electrical system. In many vehicular contexts, the Inverter 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.

12 Volt Main and Auxiliary (House) Battery Connection (Isolated Parallel)—two DC terminals
Connect your Inverter to your batteries using the following procedures—always loosely twist each pair of cables together before
connecting them separately to the appropriate DC terminal on the Inverter (positive or negative).
WARNING! Never attempt to operate your Inverter by connecting it directly to output from an alternator rather than
a battery or battery bank.
CAUTION! Observe proper polarity with all DC connections.
