Battery Connection
• Connect DC Wiring: Though your
Inverter/Charger is a
high-efficiency
converter o f
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 9.3 mm diameter (2/0
AWG))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 equip ment 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 table below for
recommendedcablesizingchart.
• Connect Ground: Using a 3.15 mm
diameter(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
specific Inverter/Charger model. All
installations must comply with national and
local codes and ordinances.
• Connect Fuse: Tripp Lite recommends
that you connect your Inverter/Charger’s
positive DC Terminal directly to a fuse and
fuseblock within 450 mm 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.
ConnectyourInverter/Chargertoyourbatteriesusingthefollowingprocedures:
WARNING! • Failure to properly ground your Inverter/Charger to 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.
