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 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 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.
See table below for recommended cable sizing chart.
• Connect Fuse: Tripp Lite recommends that you connect your battery to your Inverter/Charger's DC terminals with wiring that includes
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 the
Inverter/Charger's nameplate. See diagrams below for proper fuse placement. The battery wire with the fuse should not be grounded.
• Battery Grounding: The Inverter/Charger will operate properly with the battery negative terminal or the battery positive terminal
connected to earth ground. It will also operate properly without an earth ground connection to either battery terminal. Any battery ground
connection should be made directly from the battery terminal to earth ground.
WARNING!
• Follow all applicable electrical codes and requirements for battery grounding.
• 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.

Series Connection

In a series connection, your Inverter/Charger's Nominal DC Input Voltage must match the number of batteries multiplied by their voltage.
For example, a 48V DC Inverter/Charger requires either four 12V batteries connected in series (48 = 4 × 12) or eight 6V batteries
connected in series (48 = 8 × 6).
Contact Tripp Lite technical support for assistance with additional parallel, series or series/parallel connections.
