Battery Connection (Standard)
1. Connect your APS’s positive DC Terminal directly to a fuse.
Tripp Lite recommends that you install a recognized component fuse block and fuse within 18 inches of the battery.The fuse's rating must equal or exceed the Minimum DC Fuse Rating listed in
your APS model’s specifications on pages 14 or 15.
2. Choose a battery configuration appropriate to your batteries.
• Single Battery Connection: Refer to Diagram 4, page 33. When using a single battery, its
voltage must be equal to the voltage of your APS's Inverter Nominal Input Voltage (see
specs).
• Parallel Battery Connection: Refer to Diagram 5, page 33.When using multiple batteries in
parallel, each battery's voltage must be equal to the voltage of your APS's Inverter Nominal
Input Voltage (see specs).
• Series Battery Connection: Refer to Diagram 6, page 33.When using multiple batteries in
series, all batteries must be equal in voltage and amp hour capacity, and the sum of their voltages
must be equal to the voltage of your APS's Inverter Nominal Input Voltage (see specs).
3. Use 2/0 gauge wire ONLY to make external battery connections.
Tighten battery terminals to a torque of 4 N-m.
WARNING! Failure to follow these instructions can lead
to product failure due to excessive heating!
Battery connection cable lengths should be short as possible, and must not exceed the
Maximum Cable Length listed under Specifications, page 14.Shorter and heavier gauge cabling
limits DC voltage drop and allows for maximum transfer of current.* You must tighten your battery
terminals to approximately 4 Newton-meters of torque to create an efficient connection and prevent
excessive heating.Insufficiently tightening terminals could void your PowerVerter's warranty.
*APS models are capable of delivering a much higher wattage output for brief periods of time. Wiring should be configured to
handle this brief high-current draw. Though your APS is a high-efficiency converter of electricity, its rated output capacity is
limited by the length and gauge of the wires running from the battery to the APS.
Battery Connection (DC Vehicular)
APS systems may be permanently mounted in a car, truck or boat and connected to draw power
from the vehicle's battery .Note:An APS can ONL Y be connected to vehic le batteries with volta ge
that matches the APS's Nominal DC Input—12V vehicle batteries to 12V Nominal DC Input
APS systems, etc. (See Specifications). There are two main ways to make this sort of vehicular
battery connection. Choose the Basic Connection if you are running light hand tools or other small
appliances for a brief period of time (see Diagram 7, p. 34). Choose the Advanced Connection if
you are using your APS to power hea vy loads f or e xtended periods of time (see Diagram 8,p. 34).
The Advanced Connection incorporates a battery isolator and separate battery system to provide
battery power to your APS while preventing it from draining y our v ehicle's battery. Note:Depending
on your application, you may require more than one Deep Cycle Battery.
Caution: Never operate your APS from an alternator without a battery connected as shown in Diagrams 7 or 8, p. 34.
DC Ground Connection
APS systems must be connected to a grounded, permanent wiring system. For most installations,
the negative battery conductor must be bonded to the grounding system at one (and only one)
point in the system. All installations must comply with national and local codes and ordinances.
