Battery Connection - Tripp Lite APSX3024SW Owner's Manual

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. Use 90° C copper wire. 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 4.0 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.
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.
Series Connection
In a series connection, your Inverter/Charger's Nominal DC Input Voltage must match the number of batteries multiplied by their voltage.
A 24V DC Inverter/Charger requires either two 12V batteries connected in series (24 = 2 × 12) or four 6V batteries connected in series
(24 = 4 × 6).
Contact Tripp Lite technical support for assistance with additional parallel, series or series/parallel connections.
