Important Safety Instructions  
SAVE THESE INSTRUCTIONS!  
This manual contains important instructions and warnings that should be followed during the installation, operation and storage of all Tripp Lite  
Inverter/Chargers.  
Location Warnings  
• Install your Inverter/Charger (whether for a mobile or stationary application) in a location or compartment that minimizes exposure to  
heat, dust, direct sunlight and moisture.  
• Although your Inverter/Charger is moisture resistant, it is NOT waterproof. Flooding the unit with water will cause it to short circuit  
and could cause personal injury due to electric shock. Never immerse the unit, and avoid any area where standing water might  
accumulate. Mounting should be in the driest location available.  
• Leave a minimum of 2" clearance at front and back of the Inverter/Charger for proper ventilation. The heavier the load of connected  
equipment, the more heat will be generated by the unit.  
• Do not install the Inverter/Charger directly near magnetic storage media, as this may result in data corruption.  
• Do not install near flammable materials, fuel or chemicals.  
Battery Connection Warnings  
• The Inverter/Charger will not operate (with or without utility power) until batteries are connected.  
• Multiple battery systems must be comprised of batteries of identical voltage, age, amp-hour capacity and type.  
• Because explosive hydrogen gas can accumulate near batteries if they are not kept well ventilated, your batteries should not be  
installed (whether for a mobile or stationary application) in a “dead air” compartment. Ideally, any compartment would have some  
ventilation to outside air.  
• Sparks may result during final battery connection. Always observe proper polarity as batteries are connected.  
• Do not allow objects to contact the two DC input terminals. Do not short or bridge these terminals together. Serious personal injury  
or property damage could result.  
Equipment Connection Warnings  
Do not use a Tripp Lite APS Inverter/Charger in life support or healthcare applications where a malfunction or failure of a  
Tripp Lite APS Inverter/Charger could cause failure of or significantly alter the performance of, a life support device or medical  
equipment.  
• Corded models: Do not modify the Inverter/Charger’s plug or receptacle in a way that eliminates its ground connection. Do not use  
power adapters that will eliminate the plug’s ground connection.  
• Connect your Inverter/Charger only to a properly grounded AC power outlet or hardwired source. Do not plug the unit into itself; this  
will damage the device and void your warranty.  
You may experience uneven performance results if you connect a surge suppressor, line conditioner or UPS system to the output of the  
Inverter/Charger.  
Operation Warnings  
Your Inverter/Charger does not require routine maintenance. Do not open the device for any reason. There are no user serviceable parts  
inside.  
• Potentially lethal voltages exist within the Inverter/Charger as long as the battery supply and/or AC input are connected. During any  
service work, the battery supply and AC input connection should therefore be disconnected.  
• Do not connect or disconnect batteries while the Inverter/Charger is operating in either inverting or charging mode. Operating Mode  
Switch should be in the OFF position. Dangerous arcing may result.

Operation  
LOAD Red Indicator: This red light will ILLUMI-  
NATE CONTINUOUSLY whenever the inverter is  
functioning and the power demanded by connected  
appliances and equipment exceeds 100% of load  
capacity. The light will FLASH to alert you when the  
inverter shuts down due to a severe overload or over-  
heating. If this happens, turn the operating mode switch “OFF”;  
remove the overload and let the unit cool. You may then turn the  
operating mode switch to either “AUTO/REMOTE” or “CHARGE  
ONLY” after it has adequately cooled. This light will be off when  
AC power is supplying the load.  
Switch Modes  
After configuring, mounting and connecting your Inverter/Charger, you  
are able to operate it by switching between the following operating  
modes as appropriate to your situation:  
AUTO/REMOTE: Switch to this mode when you  
need constant, uninterrupted AC power for connected  
appliances and equipment. The Inverter/Charger will  
continue to supply AC power to connected equipment  
and to charge your connected batteries while utility-  
or generator-supplied AC power is present. Since the  
inverter is ON (but in Standby) in this mode, it will automatically  
switch to your battery system to supply AC power to connected  
equipment in the absence of a utility/generator source or in over/under  
voltage situations. “AUTO/REMOTE” also enables an optional  
remote control module (Tripp Lite model APSRM4, sold separately  
or included with select models) to function when connected to the  
unit. This setting also allows operation of the Redundant Operating  
Mode Switch mounted on the top panel of select models  
BATTERY Indicator Lights: These three lights will illuminate in  
several sequences to show the approximate charge level of your con-  
nected battery bank and alert you to two fault conditions:

CHARGE ONLY: Switch to this mode when you  
are not using connected appliances and equipment in  
order to conserve battery power by disabling the  
inverter. The Inverter/Charger will continue to supply  
AC power to connected equipment and charge con-  
nected batteries while utility- or generator-supplied  
AC power is present. However, since the inverter is OFF in this  
mode, it WILL NOT supply AC power to connected equipment in the  
absence of a utility/generator source or in over/under voltage situations.

OFF: Switch to this mode to shut down the  
Inverter/Charger completely, preventing the inverter  
from drawing power from the batteries, and preventing  
utility AC from passing through to connected equipment  
or charging the batteries. Use this switch to automatically  
reset the unit if it shuts down due to overload or over-  
heating. First remove the excessive load or allow the unit to suffi-  
ciently cool (applicable to your situation). Switch to “OFF”, then  
back to “AUTO/REMOTE” or “CHARGE ONLY” as desired. If  
unit fails to reset, remove more load or allow unit to cool further and  
retry. Use an optional remote control module (Tripp Lite model  
APSRM4, sold separately or included with select models) to reset  
unit due to overload only.

indicate when the Inverter/Charger is automatically  
“boosting” abnormally low AC voltage or “cutting”  
abnormally high AC voltage without relying on bat-  
tery power. This function is automatic and requires  
no action on the user’s part.  
Indicator Lights  
Your Inverter/Charger (as well as an optional Tripp Lite Remote  
Control Module, sold separately or included with select models) is  
equipped with a simple, intuitive, user-friendly set of indicator lights.  
These easily-remembered “traffic light” signals will allow you, shortly  
after first use, to tell at a glance the charge condition of your batteries,  
as well as ascertain operating details and fault conditions.  
Resetting Your Inverter/Charger  
LINE Green Indicator: If the operating mode  
switch is set to “AUTO/REMOTE,” this light will  
ILLUMINATE CONTINUOUSLY when your con-  
nected equipment is receiving continuous AC power  
supplied from a utility/generator source.  
to Restore AC Power  
Your Inverter/Charger may cease supplying AC power or DC charging  
power in order to protect itself from overload or to protect your elec-  
trical system. To restore normal functioning:  
Overload Reset: Switch operating mode switch to “OFF” and  
remove some of the connected electrical load (ie: turn off some of  
the AC devices drawing power which may have caused the overload  
of the unit). Wait one minute, then switch operating mode switch  
back to either “AUTO/REMOTE” or “CHARGE ONLY.”  
If the operating mode switch is set to “CHARGE ONLY,” this light  
will FLASH to alert you that the unit’s inverter is OFF and will NOT  
supply AC power in the absence of a utility/generator source or in  
over/under voltage situations.  
INV (Inverting) Yellow Indicator: This light will  
ILLUMINATE CONTINUOUSLY whenever connected  
equipment is receiving battery-supplied, inverted AC  
power (in the absence of a utility/generator source or  
in over/under voltage situations). This light will be  
off when AC power is supplying the load. This light  
will FLASH to alert you if the load is less than the Battery Charge  
Conserver (Load Sense) setting.  
Output Circuit Breaker Reset: Alternatively, check output circuit  
breaker(s) on the unit’s front panel. If tripped, remove some of the elec-  
trical load, then wait one minute to allow components to cool before  
resetting the circuit breaker. See Troubleshooting for other possible  
reasons AC output may be absent.

* Most of your connected appliances and equipment will perform adequately when your Inverter/Charger’s High AC Input Voltage Point is left in the factory setting and its Low AC Voltage Input  
Point is set to 95V. However, if the unit frequently switches to battery power due to momentary high/low line voltage swings that would have little effect on equipment operation, you may wish to  
adjust these settings. By increasing the High AC Voltage Point and/or decreasing the Low AC Voltage Point, you will reduce the number of times your unit switches to battery due to voltage swings.  
Group B DIP Switches (Select Models)  
B1 B2  
Select Load Sharing—OPTIONAL (Not on 612, 750 and 1250 Models)  
Your Inverter/Charger features a high-output battery charger that can draw a significant amount of AC power from your utility source or  
generator when charging at its maximum rate. If your unit is supplying its full AC power rating to its connected heavy electrical loads at the  
same time as this high charging occurs, the AC input circuit breaker could trip, resulting in the complete shut off of pass-through utility power.  
To reduce the chance of tripping this breaker, Inverter/Chargers may be set to automatically limit the charger output. This keeps the sum of  
the unit’s AC load and charge power within the circuit breaker rating. This charger-limiting function has four settings, allowing you to  
reduce the charger’s draw lower and lower, as needed, if the AC input circuit breaker keeps tripping under the normal AC loads of devices  
you have connected downline from the unit. The figures on the next page show how to set your DIP Switches to determine how heavy the  
connected load can be on your Inverter/Charger before charger-limiting begins.

on low charging, you lengthen the life of  
your batteries (especially smaller ones).  
CAUTION: When switching to the High Charge Amp setting, the user must ensure that the amp  
hour capacity of their battery system exceeds the amperage of the High Charge Amp setting or  
the batteries may be damaged or degraded.  
Set Battery Charge Conserver (Load Sense) Control—OPTIONAL (Not on 612, 750 or 1250 Models)  
In order to save battery power, the unit's inverter automatically shuts off in the absence of any power demand from  
connected equipment or appliances (the electrical load). When the Inverter/Charger detects a load, it automatical-  
ly turns its inverter function on. Users may choose the minimum load the Inverter/Charger will detect by adjusting  
the Battery Charge Conserver Control (see diagram). Using a small tool, turn the control clockwise to lower the  
minimum load that will be detected, causing the inverter to turn on for smaller loads. When the control is turned  
OFF  
(LESSER

fully clockwise, the inverter will operate even when there is no load. Turn the control counterclockwise to increase the minimum load that  
will be detected, causing the inverter to stay off until the new minimum load is reached.  
NOTE: The factory setting for the control is fully clockwise. However, based on the threshold load to which you’d like the inverter to respond, you should adjust the control counterclockwise to reduce  
its sensitivity until the inverter is active only when connected equipment or appliances are actually in use.  
Connect Remote Control—Optional (All models)  
All models feature an 8-conductor telephone style receptacle on the front panel for use with an optional remote control module (Tripp Lite  
model APSRM4, sold separately or included with select models). The remote module allows the Inverter/Charger to be mounted in a compart-  
ment or cabinet out of sight, while operated conveniently from a remote location. See instructions packed with the remote control module.  
Connect Battery Temperature Sensing Cable—OPTIONAL (Select Models)  
The battery temperature sensing function prolongs battery life by adjusting the charge float voltage level based on battery temperature. Connect  
the sensor cable (the cable, included with select models, has an RJ style connector on one end and a black sensor on the other) to the RJ  
style jack located on the side of the Inverter/Charger labeled “Remote Temp. Sense.” Affix the sensor to the side of your battery below the  
electrolyte level. To guard against false readings due to ambient temperature, place the sensor between batteries, if possible, or away from  
sources of extreme heat or cold. If the sensor cable is not used, the Inverter/Charger will charge according to its default 25º C values.  
7A  
 
Battery Selection  
Select Battery Type  
Select “Deep Cycle” batteries to enjoy optimum performance from your Inverter/Charger. Batteries of either Wet-Cell (vented) or Gel-Cell /Absorbed  
Glass Mat (sealed) construction are ideal. 6-volt “golf cart,” Marine Deep-Cycle or 8D Deep-Cycle batteries are also acceptable. You must  
set the Inverter/Charger’s Battery Type DIP Switch (see Configuration section for more information) to match the type of batteries you connect  
or your batteries may be degraded or damaged over an extended period of time.  
Match Battery Amp-Hour Capacity to Your Application  
Select a battery or system of batteries that will provide your Inverter/Charger with proper DC voltage and an adequate amp-hour capacity  
to power your application. Even though Tripp Lite Inverter/Chargers are highly-efficient at DC-to-AC inversion, their rated output capacities  
are limited by the total amp-hour capacity of connected batteries plus the output of an alternator when one is used.  
Example  
• STEP 1) Determine Total Wattage Required  
Add the wattage ratings of all equipment you will connect to your  
Tools  
¼" Drill  
Orbital Sander  
Cordless Tool Charger  
Inverter/Charger. Wattage ratings are usually listed in equipment manuals  
or on nameplates. If your equipment is rated in amps, multiply that number  
times AC utility voltage to estimate watts. (Example: a ¼ in. drill requires  
2½ amps. 2½ amps × 120 volts = 300 watts.)  
NOTE: Your Inverter/Charger will operate at higher efficiencies at about 75% - 80% of nameplate rating.

100W  
=
540W  
• STEP 2) Determine DC Battery Amps Required  
Divide the total wattage required (from step 1, above) by the battery voltage  
540 watts ÷ 12V = 45 DC Amps  
(i.e. 12, 24, 36 or 48) to determine the DC amps required.  
• STEP 3) Estimate Battery Amp-Hours Required  
Multiply the DC amps required (from step 2, above) by the number of hours  
you estimate you will operate your equipment exclusively from battery  
power before you have to recharge your batteries with utility- or genera-  
tor-supplied AC power. Compensate for inefficiency by multiplying this  
number by 1.2. This will give you a rough estimate of how many amp-hours  
of battery power (from one or several batteries) you should connect to  
your Inverter/Charger.  
45 DC Amps × 5 Hrs. Runtime  
× 1.2 Inefficiency Rating = 270 Amp-Hours  
NOTE: Battery amp-hour ratings are usually given for a 20-hour discharge rate. Actual amp-hour capacities  
are less when batteries are discharged at faster rates. For example, batteries discharged in 55 minutes  
provide only 50% of their listed amp-hour ratings, while batteries discharged in 9 minutes provide as little  
as 30% of their amp-hour ratings.  
• STEP 4) Estimate Battery Recharge Required, Given Your Application  
You must allow your batteries to recharge long enough to replace the  
charge lost during inverter operation or else you will eventually run down  
your batteries. To estimate the minimum amount of time you need to  
recharge your batteries given your application, divide your required battery  
amp-hours (from step 3, above) by your Inverter/Charger’s rated charging  
amps (see Specifications section).  
270 Amp-Hours ÷ 30 Amps  
Inverter/Charger Rating = 9 Hours Recharge  
NOTE: For Tripp Lite Inverter/Chargers providing 1000 watts or less of continuous AC power, a full-size  
battery will normally allow sufficient power for many applications before recharging is necessary. For  
mobile applications, if a single battery is continuously fed by an alternator at high idle or faster, then recharging  
from utility or generator power may not be necessary. For Tripp Lite Inverter/Chargers over 1000 watts used  
in mobile applications, Tripp Lite recommends you use at least two batteries, if possible fed by a heavy-duty  
alternator anytime the vehicle is running. Tripp Lite Inverter/Chargers will provide adequate power for  
ordinary usage within limited times without the assistance of utility or generator power. However, when  
operating extremely heavy electrical loads at their peak in the absence of utility power, you may wish to  
“assist your batteries” by running an auxiliary generator or vehicle engine, and doing so at faster than  
normal idling.

Tripp Lite’s Lateral Mounting Bracket (pre-installed on select models, but also  
available as an optional accessory from Tripp Lite*) provides a rigid surface  
for lateral mounting in vehicular or non-vehicular applications. Consult the  
instructions packed with the Lateral Mounting Bracket for complete mounting  
information. Note: your Inverter/Charger is not designed nor covered under  
warranty for vertical or inverted mounting in a vehicular application. Such  
mounting may be possible, however, when your Inverter/Charger is properly  
secured to a Lateral Mounting Bracket. As with any mounting, user is respon-  
sible for determining if the Inverter/Charger can be mounted safely relative to  
their application. Since securing an Inverter/Charger to a Lateral Mounting  
Bracket which is not factory pre-installed will require some modifications to  
the Inverter/Charger cabinet, please consult the Lateral Mounting Bracket  
* Contact Tripp Lite for ordering information.

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.  
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,  
36 or 48) must match the voltage of your battery or batteries (12, 24, 36 or 48). 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 match the number of batteries multiplied by their voltage. For  
example, a 24V DC 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 match the 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.  
Contact Tripp Lite technical support for assistance with additional parallel, series or series/parallel connections.

NOTE: Select models include two positive and two negative DC terminals. Using the same connection architecture illustrated in the diagrams, run two 2/0 gauge cables from the Inverter/Chargers  
two negative terminals to the batterys single negative terminal; run two 2/0 gauge cables from the Inverter/Chargers two positive terminals, through two UL-listed fuses and fuse blocks, or equivalent,  
(one on each cable), to the batterys single positive terminal. Use the equivalent of two 2/0 cables in all other connections within the battery system. Connection to two DC Terminals: It is acceptable to  
use two cables to connect your battery to only one positive and one negative DC terminal, however, your Inverter/Charger will provide reduced output power. It doesnt make a difference which pos-  
itive and negative terminal you choose for the connection because both positive terminals are internally bonded and both negative terminals are also internally bonded. In this connection, you must  
run one positive cable through one user-supplied UL-listed fuse and fuse block.  
10A  
 
AC Input/Output Connection  
To avoid overloading your Inverter/Charger, be sure to match the power requirements of the equipment you plan to run at any one time (add their  
total watts) with the output wattage capacity of your Inverter/Charger model (see Specifications). When figuring the power requirements  
of your equipment, do not confuse “continuous” wattage with “peak” wattage ratings. Most electric motors require extra power at start-up  
(“peak” wattage) than required to run continuously after start-up, sometimes over 100% more. Some motors, such as in refrigerators and  
pumps, start and stop intermittently according to demand, requiring “peak” wattage at multiple, unpredictable times during operation.  
• DoubleBoostFeature  
• OverPowerFeature  
Tripp Lite Inverter/Chargers deliver up to twice their nameplate  
rated wattage for up to 10 seconds,* providing the extra power  
needed to cold start heavy-duty tools and equipment.  
Tripp Lite Inverter/Chargers deliver up to 150% of their name  
plate rated wattage for up to 1 hour,* providing plenty of reserve  
power to reliably support tools and equipment longer.  
* Actual duration depends on battery age, battery charge level and ambient temperature.  
Connection for Models with Cords and Receptacles  
Plug the Inverter/Charger’s AC input cord into an outlet providing 120V AC, 60Hz. power. Make sure that the circuit you connect your  
Inverter/Charger to has adequate overload protection, such as a circuit breaker or a fuse. To make use of AC output (either utility/genera-  
tor pass-through power or inverter power) simply plug your equipment into the Inverter/Charger's AC receptacles. Any equipment you con-  
nect to it will benefit from your Inverter/Charger’s built-in ISOBAR® surge protection!  
Warning! Consult a qualified electrician and follow all applicable electrical codes  
and requirements for hardwire connection. Disconnect both DC input and AC utility  
supply before attempting hardwiring.  
Connection for Models with Hardwire Terminals  
Remove the screws and cover plate over the hardwire terminal box. Remove the knockout covers closest to the desired electrical source and  
to your equipment. Attach ½" diameter conduits (user-supplied) to the knockouts and thread wires through. Connect the conduits to each  
other with the ground bond connection supplied.
