Tripp Lite APINT Series, APSX Battery Connection

Non-Vehicular or Vehicular

Non-vehicular applications include stationary configurations as well as mobile configurations that are not integrated into a vehicle’s electrical

system. In a parallel connection, your Inverter/Charger’s Nominal DC Input Voltage (listed in the Specifications section as either 12, 24 or

36) must match the voltage of your battery or batteries (12, 24 or 36). For example, a 12V DC Inverter/Charger would require 12V DC

from your battery system.

In a series connection, your Inverter/Charger’s Nominal DC Input Voltage must matchthe number of batteries multiplied by their voltage. For

example, a 24VDC Inverter/Charger would require either two 12V batteries connected in series (24 = 2 × 12) or four 6V batteries connected

in series (24 = 4 × 6).

In vehicular applications, your Inverter/Charger’s Nominal DC Input Voltage must matchthe voltage of your battery or batteries—

12 Volts. Although it is possible to connect your Inverter/Charger to the main battery within your vehicle’s electrical system, in the normal

vehicular context, the Inverter/Charger is 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 DC Wiring: Though your

Inverter/Charger is a

high-efficiency con-

verter of electricity,

its rated output

capacity is limitedby

the length and gauge

of the cabling run-

ning 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 effi-

cient connection and to prevent excessive

heating at this connection. Insufficient tight-

ening of the terminals could void your war-

ranty. See Specifications (included sepa-

rately) page forMinimum Recommended

Cable Sizing Chart.

• Connect Ground: Using a #8 AWG wire

or larger directly connect the Main Ground

Lug to the vehicle’s chassiso r 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 all of your Inverter/Charger’s

positive DC Terminals directly to a fuse(s)

and fuse block(s) within 45 cm (18 inches)

of the battery. The fuse’s rating must equal

or exceed the Minimum DC Fuse Rating

listed in your Inverter/Charger’s specifica-

tions. See Specifications for fuse and fuse

block recommendations. See diagrams

below for proper fuse placement.

Connect your Inverter/Chargerto 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 by connecting it directly to output from an

alternator rather than a battery or battery bank.

• Observe proper polarity with all DC connections.
