Quiet, Economical Mobile Power…
Congratulations! You've purchased one of the most advanced, feature-rich Inverters designed for utility/work truck applications. Tripp Lite
Utility/Work Truck Inverters provide quiet, convenient mobile power for every application: computers, TVs, electronic test equipment, power
tools, pumps, compressors, blowers, lights, power supplies, radios, cell phone chargers and more. Since Tripp Lite Inverters draw power directly from vehicle batteries, they are the quiet, economical power alternative in residential environments or late-night job sites—without the noise,
fumes, capital outlays, maintenance costs and occasional power overkill of generators! For generator-equipped trucks, they provide crews with
the option of silent power.*
…With Optional Power-Boosting Functionality
In today's cost-cutting climate, fleet managers must get the most out of every vehicle—keeping trucks in the field longer, operating an evergrowing array of power tools. Standard vehicle alternators and batteries, however, often can't keep up with the increased power demand. When
alternators recharge batteries at a slower rate than they are discharged, that leaves a power deficit for the next day's jobs and dramatically shortens battery service life. Tripp Lite Utility/Work Truck Inverters, with the addition of a built-in battery charger, help to overcome this power
deficit. When optionally connected to shore power at the end of the day, Tripp Lite Utility/Work Truck Inverters quickly and safely recharge
vehicle batteries, ensuring that maximum power is available for the next day's service schedule.** In addition, Tripp Lite Utility/Work Truck
Inverters out-muscle other inverters on the market with peak power—handling tough loads like motors, compressors and incandescent lamps
with ease.

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 Inverters.
Location Warnings
Equipment Connection Warnings
• The Inverter must be located in an enclosed compartment,
shielded from outside weather conditions.
• Although your Inverter 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 for proper ventilation. To avoid automatic Inverter
shutdown due to overtemperature, any compartment that
contains the Inverter must be properly ventilated with adequate
outside air flow. The heavier the load of connected equipment,
the more heat will be generated by the unit.
• Do not install the Inverter directly near magnetic storage media,
as this may result in data corruption.
• Do not install near flammable materials, fuel, chemicals or gasses
Do not use a Tripp Lite Inverter in life support or healthcare
applications where a malfunction or failure of a Tripp Lite
Inverter could cause failure of, or significantly alter the performance of, a life support device or medical equipment.
• You may experience uneven performance results if you connect
a surge suppressor, line conditioner or UPS system to the output
of the Inverter.
• Do not modify the Inverter’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 only to a properly grounded AC power
outlet. Do not plug the unit into itself; this will damage the
device and void your warranty.
Operation Warnings
• Your Inverter 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 as long as
the battery supply and/or AC input are connected. During any
service work, the battery supply and AC input connection (if
any) should therefore be disconnected.
• Do not connect or disconnect batteries while the Inverter is
operating in either inverting or charging mode. Dangerous arcing
may result. Operating Mode Switch should be in the OFF position.
Battery Connection Warnings
• The Inverter 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 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.

Operation
Switch Modes
After configuring, mounting and connecting your Inverter, you can
operate it by switching between the following operating modes as
appropriate to your situation:
AUTO/REMOTE: Switch to this mode during normal operational conditions. When service vehicles
are deployed, the Inverter/Charger will draw from
connected batteries to supply AC power to connected equipment. This mode also enables the optional
remote control module (included) to function when
connected to the unit. It is fine to leave the switch in this mode at the
end of the day (when service vehicles are parked) especially when
relying upon the remote control as your main control. Note: when
connected to shore power, AC power is not only routed to the battery charger but passes through to the GFCI outlets as well.
Operation section continued on next page.
OFF: Switch to this mode during normal operational
conditions if you want to completely shut down the
unit's inverter, cut-off the remote control module's
functionality and shut off power to the AC outlets.
For extended periods of “dry dock” time, switch to
this mode if the Inverter/Charger is not plugged into shore power.
CHARGE ONLY: Switch to this mode when service vehicles are parked and (optionally) connected to
shore power for extended periods of "dry dock"
time, as with seasonal-use trucks. This mode will
enable the unit's charger, but will disable the unit's
inverter. Note: when connected to shore power, AC power is not
only routed to the battery charger but passes through to the GFCI
outlets as well.

Indicator Lights
Your Inverter (as well as an optional Tripp Lite Remote Control Module) 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 a wide variety of operating details.
“LINE Green LED”: If the operating mode switch
is set to “AUTO/REMOTE”, this light will ILLUMINATE CONTINUOUSLY when your vehicle is connected to shore (or generator) power.
If the operating mode switch is set to “CHARGE
ONLY”, this light will BLINK to alert you that the unit’s inverter
is OFF and will NOT supply AC power in the absence of a
utility/generator source.
“INV” (Inverting) Yellow LED: This light will
ILLUMINATE CONTINUOUSLY whenever connected equipment is receiving battery-supplied,
inverted AC power.
“LOAD” Red LED: This red light will ILLUMINATE CONTINUOUSLY whenever the inverter is
functioning and the power demanded by connected
equipment exceeds 100% of load capacity. The light
will BLINK to alert you when the inverter shuts
down due to a severe overload or overheating. 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.
"BATT VOLT" or "BATT VOLT/CHRG CURR" LEDs: Depending on your model, this set of three LEDs will display different
operating information.
750 and 1250 models: Whether the switch is in the "AUTO/REMOTE" or "CHARGE ONLY" position, the LEDs indicate the approximate
charge level and voltage of your connected battery bank and alert you to several fault conditions. See "BATT VOLT" LED Function Chart
for details.
2012 models only: If the switch is in the "AUTO/REMOTE" position, the LEDs indicate the approximate charge level and voltage of your
connected battery bank and alert you to several fault conditions. See "BATT VOLT" LED Function Chart for details.
If the switch is in the "CHARGE ONLY" position, the LEDs indicate the approximate charge rate of the Inverter. See "CHRG CURR" LED
Function Chart for details. Note: the charge rates in the chart are expressed as percentages of the Inverter's rated charging amps. Refer to
the specifications to determine the charging amps of your specific model.

Resetting Your Inverter to Restore AC Power
Your Inverter may cease supplying AC power or DC charging power
in order to protect itself from overload or to protect your electrical 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.”

Output Circuit Breaker Reset: Alternatively, check output circuit
breaker(s) on the unit's front panel. If tripped, remove some of the
electrical 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.
*Approximately ½ second on, ½ second off. See Troubleshooting section. Inverter shutdown
protects battery against damage due to excessive discharge.** Approximately ¼ second on, ¼
second off. Charger shutdown protects battery against damage due to overcharge. May also
indicate a battery charger fault exists. See Troubleshooting section.

Configuration
Note: Tripp Lite recommends that users only change settings for the DIP switches and controls described below. Additional DIP
switches and controls located in the unit's DIP switch panel or in other areas are preset to optimize the unit's operation. Setting
these DIP switches or controls may adversely affect the unit's operation.
Required Configuration
DIP SWITCH 1

CAUTION: The Battery Type DIP Switch setting must match the type of batteries you connect, or your batteries may be degraded or damaged over an extended period of time. See “Battery
Selection,” for more information.
Optional Configuration
DIP SWITCH 3
Select Equalize Battery Charge—OPTIONAL
(For use when using auxiliary batteries. See Battery Selection section.)
This DIP Switch is momentarily engaged to
begin the process of equalizing the charge
state of your battery’s cells by time-limited
overcharge of all cells. This can extend the
useful life of certain types of batteries; consult with your battery’s manufacturer to determine if your batteries
could benefit from this process. The charge equalization process is automatic; once started, it can only be stopped by removing the input power.
Setting Procedure
• Move to “Equalize” (DOWN) position for three seconds.
• Move to “Reset” (UP) position and leave it there. This is the
factory default setting.
CAUTION: Do not leave DIP switch #B3 in the down position after beginning process. Battery
charge equalization should only be performed in strict accordance with the battery manufacturer’s
instructions and specifications.
DIP SWITCH 4
Set Battery Charging Amps—OPTIONAL
Check specifications for your unit’s high- and
low-charging amp options. By setting on
high charging, your batteries will charge at
maximum speed. By setting on low charging (factory setting), you lengthen the life
of your batteries (especially smaller ones).

Connect Remote Control—OPTIONAL
An 8-conductor telephone style receptacle on the front panel is included for use with an optional remote control module (included). The
remote module allows the Inverter to be mounted in a compartment or cabinet out of sight, while operated conveniently from within the
cab of your vehicle. See instructions packed with the remote control module.
Connect Battery Temperature Sensing Cable—OPTIONAL—(Select models only)
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, 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 labeled “Remote Temp. Sense.” With user-supplied electrical or duct tape, affix the sensor to the side of
the battery below the electrolyte level. Make sure that nothing, not even tape, comes between the sensor and the side of the battery. 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 will charge according to its default 25º C values.
Utilize Automatic Generator Starter Capability—OPTIONAL—(Select models only)
Although not typically applicable to utility/work truck situations, select Inverter models offer an RJ type modular
jack on the side panel labeled "Generator Start." If your current fleet is already equipped with generators,
select Tripp Lite Utility/Work Truck Inverters provide your crews the option of quiet power for residential environments or late-night job sites. When wattage loads are within the Inverter's ratings, crews can avoid the power
overkill, fuel consumption, fumes and noise of generator use. To tie the Inverter and generator together, simply connect the generator's AC
power output to the Inverter's AC input cord. The Inverter will automatically charge the battery when generator power is available, and generator power will automatically pass-through for use via the Inverter's GFCI receptacles. To automatically activate the generator when battery voltage runs low, attach to vehicle generator ON/OFF switching mechanism with user-supplied cable (see Pin Configuration Diagram).
Once attached, the interface will allow the Inverter to automatically switch a vehicle generator on when connected battery voltage levels
are low (11.6 VDC) and switch it off when battery voltage levels are high (14.1 VDC).

Battery Selection (optional)
To extend Inverter runtimes without upgrading your truck's alternator, you may wish to create an “intra-day” power reservoir by adding
auxiliary batteries to your system, typically tied to the chassis battery via an isolator. Large intra-day power deficits, despite overnight
charging, are an indicator that a larger alternator may be necessary. Although the Inverter can supply AC power without the vehicle engine
running, the alternator of a running engine replaces lost DC voltage. Especially when operating heavier electrical loads, you may wish to
“assist your batteries” by idling the vehicle engine, or during extra-heavy duty use, by running the engine at faster-than-normal idling.
Select Auxiliary Battery Type (if any)
If you elect to add an auxiliary battery(ies), select “Deep Cycle” batteries to receive optimum performance from your Inverter. Although
ordinary vehicle batteries rated in Cold Cranking Amps (CCA) are an acceptable source of 12V input, any auxiliary battery(ies) would ideally be true Deep Cycle batteries, lengthening the operational lifetimes of the auxiliary battery bank.
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’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. In
many cases, the vehicle battery may be the only one installed. Auxiliary batteries must have the same voltage as vehicle batteries if they
are connected to each other.
Match Battery Amp-Hour Capacity to Your Application
Select a battery or system of batteries that will provide your Inverter with proper DC voltage and an adequate amp-hour capacity to power
your application. Even though Tripp Lite Inverters are highly efficient at DC-to-AC inversion, their rated output capacities are limited by the
total amp-hour capacity of connected batteries and the support of your vehicle’s alternator if the engine is kept running.
Example
• STEP 1: Determine Total Wattage Required
Add the wattage ratings of all equipment you will connect to your Inverter. 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 determine watts.
(Example: a ¼ in. drill requires 2½ amps. 2½ amps × 120 volts = 300 watts .)
¼" Drill
Note: Your Inverter will operate at higher efficiencies at about 75% - 80% of nameplate rating.
300W
• STEP 2: Determine DC Battery Amps Required
Divide the total wattage required (from step 1, above) by the battery voltage (12)
to determine the DC amps required.
• STEP 3: Estimate Battery Amp-Hours Required (for operation unsupported
by the alternator)
Multiply the DC amps required (from step 2, above) by the number of hours you
estimate you will operate your equipment without recharging the batteries by running the vehicle engine, or via shore or generator input to the Inverter's battery
charger. 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.

540 watts ÷ 12V = 45 DC Amps
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
If your vehicle's alternator does not replace all battery voltage inverted to support your equipment, you must allow your batteries to recharge long enough to
replace the charge lost during inverter operation to avoid eventual run-down of
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’s rated charging amps.

Battery Connection
Connect your Inverter to your batteries using the following procedures:
• Connect DC Wiring: Though your
Inverter is a highefficiency transformer of electricity,
its rated output
capacity is limited by
the length and gauge DC Connectors
of the cabling running from the battery to the
unit. Use the shortest length and largest diameter cabling (maximum 2/0 gauge) to fit your
Inverter’s DC Input terminals. Shorter and
heavier gauge cabling reduces DC voltage
drop and allows for maximum transfer of
current. Your Inverter 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 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 separate
Specifications page for Minimum
Recommended Cable Sizing Chart.
• Connect Ground: Using a #8 AWG wire
or larger directly connect the Main Ground
Lug to the vehicle’s chassis or earth ground.
See the Feature Identification section to locate
the Main Ground Lug on your specific
Inverter model. All installations must comply with national and local codes and ordinances.
• Connect Fuse: NEC (National Electrical
Code) article 551 requires that you connect all
of your Inverter’s positive DC Terminals
directly to a UL-listed fuse(s) within 18 inches of the battery. The fuse’s rating must equal
or exceed the Minimum DC Fuse Rating listed in your Inverter’s specifications. See
Specifications for fuse recommendations. See
diagrams below for proper fuse placement.
WARNING! • Failure to properly ground your Inverter to a vehicle’s chassis or earth ground may
result in a lethal electrical shock hazard.
• Never attempt to operate your Inverter by connecting it directly to output from an
alternator rather than a battery or battery bank.
• Observe proper polarity with all DC connections.
Vehicular
Your Inverter’s Nominal DC Input Voltage must match the voltage of your battery or batteries—12 Volts in most vehicular applications.
In most vehicles, the Inverter will be connected to the main battery within your vehicle's electrical system. However, it is also possible to
connect your Inverter to one or more dedicated auxiliary (house) batteries which are isolated from the drive system to prevent possible
draining of the main battery.

AC Input/Output Connection
To avoid overloading your Inverter, 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 model. 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 pumps, start and stop intermittently according to demand, requiring “peak wattage” at multiple, unpredictable times during operation. DoubleBoost™ Feature: Tripp Lite Inverters 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. OverPower™ Feature: Tripp Lite Inverters 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 model, battery age, battery charge level and ambient temperature.
Plug the Inverter’s AC input cord into an extension cord and then into an outlet providing 120V AC, 60Hz. power. Make sure that the circuit you connect your Inverter to has adequate overload protection, such as a circuit breaker or a fuse. Plug your equipment into the Inverter’s
AC receptacles.
Service
Before returning your Inverter for service, follow these steps: 1.) Review the installation and operation instructions to ensure that the service problem does not originate from a misreading of the instructions. Also, check that the circuit breaker(s) are not tripped.* 2.) If the problem continues, do not contact or return the Inverter to the dealer. Instead, call Tripp Lite at (773) 869-1233. A service technician will ask
for the Inverter’s model number, serial number and purchase date and will attempt to correct the problem over the phone. 3.) If the problem requires service, the technician will issue you a Returned Material Authorization (RMA) number, which is required for service.
Securely pack the Inverter to avoid damage during shipping. Do not use Styrofoam beads for packaging.** Any damages (direct, indirect,
special, incidental or consequential) to the Inverter incurred during shipment to Tripp Lite or an authorized Tripp Lite service center is not
covered under warranty. Inverters shipped to Tripp Lite or an authorized Tripp Lite service center must have transportation charges prepaid.
Mark the RMA number on the outside of the package. If the Inverter is within the warranty period, enclose a copy of your sales receipt.
Return the Inverter for service using an insured carrier to the address given to you by the Tripp Lite service technician.
* This is a common cause of service inquiries which can be easily remedied by following the resetting instructions in this manual. ** If you require packaging, the technician can arrange to send
you proper packaging.
Maintenance
Your Inverter requires no maintenance and contains no user-serviceable or replaceable parts, but should be kept dry at all times. Periodically
check, clean and tighten all cable connections, as necessary, both at the unit and at the battery.
