Important Safety 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
• 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. To avoid automatic Inverter/Charger
shutdown due to overtemperature, any compartment that contains the Inverter/Charger 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/Charger directly near magnetic storage media, as this may result in data corruption.
• Do not install near flammable materials, fuel or chemicals.
• Do not mount unit with its front or rear panel facing down (at any angle). Mounting in this manner will seriously inhibit the unit's
internal cooling, eventually causing product damage not covered under warranty.
• Install in land vehicles only.
Battery Connection Warnings
• 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
In life support applications where failure of this equipment can reasonably be expected to cause the failure of life support
devices or to significantly affect their safety or effectiveness, such devices should be provided with at least one backup power
source by the ambulance/EMS vehicle operator.
• You may experience uneven performance results if you connect a surge suppressor, line conditioner or UPS system to the output of
the Inverter/Charger.
• 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. Do not plug the unit into itself;
this will damage the device and void your warranty.
• The Tripp Lite Inverter/Charger includes GFCI (ground fault circuit interrupter)-protected AC output receptacles.
• The main grounding lug should be connected to the vehicle chassis with a minimum #8 AWG wire.
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 (if any) 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 DC OFF position. Dangerous arcing may result.
Caution: These models have a failsafe AC pass-through feature where the AC output will be live (if AC input is
available) even though the operating mode switch is set to DC OFF.
Feature Identification
Identify the premium features on your specific model and quickly locate instructions on how to maximize their use.
Configuration DIP Switches: optimize Inverter/Charger operation
depending on your application. See Configuration section for
setting instructions.
Operating Mode Switch: controls Inverter/Charger operation.
The "AUTO/REMOTE" setting ensures your equipment receives
constant, uninterrupted AC power. It also enables the Inverter/
Charger to be remotely monitored and controlled with an
optional remote module (Trip Lite model APSRM4, sold separately). The "CHARGE ONLY" setting allows your batteries to
return to full charge faster by turning the inverter off which halts
battery discharging. The "DC OFF" setting de-energizes the unit
and connects AC OUT to AC IN. See Operation section for
setting instructions.
"LINE", "INVERT", "LOAD" LEDs: show whether the
Inverter/Charger is operating from AC line power or DC battery
power. It also warns you if the connected equipment load is too
high. See Operation section for instructions on reading the indicator lights.
"BATT VOLTAGE" LEDs: these three lights will turn ON in
several sequences to show approximate battery level. See Operation
section for instructions on reading the indicator lights.
DC Power Terminals: connect to your battery terminals. See
Battery Connection section for instructions. The included Quick
Connect Battery Cable Assembly 5A may be used to simplify
unit or battery replacement.
Ground Fault Circuit Interrupter (GFCI) AC Receptacles:
allow you to connect equipment that would normally be plugged
into a utility outlet. They feature ground fault interrupter
switches that trip if there is excessive current on the ground
safety wire.
AC Input Cord: connects the Inverter/Charger to any source of
utility- or generator-supplied AC power. See AC Input/Output
Connection section for instructions.
Resettable Circuit Breakers: protect your Inverter/Charger against
damage due to overload or charger failure. See Operation
section for resetting instructions.
Remote Control Module Connector: allows remote monitoring
and control with a remote control module (Tripp Lite model
APSRM4 9A , included with this model). See remote module
owner’s manual for connection instructions.
Battery Charge Conserver (Load Sense) Dial: conserves
battery power by setting the low-load level at which the Inverter/
Charger’s inverter automatically shuts off. See Configuration
Section for setting instructions.
Main Ground Lug: properly grounds the Inverter/Charger to
vehicle grounding system or to earth ground. See Battery
Connection section for instructions.
Multi-Speed Cooling Fan: quiet, efficient fan prolongs equipment
service life.

Switch Modes
This light will BLINK to alert you if the load is less than the Battery
Charge Conserver (Load Sense) setting.
“LOAD” Red LED: This red light will ILLUMINATE
CONTINUOUSLY whenever the inverter is functioning and the power demanded by connected appliances and 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 to “DC 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.
"BATT VOLTAGE" LEDs: If the operating mode 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 Chart for
charge and voltage levels.
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 utilityor 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, included with
this model) to function when connected to the unit.
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
connected 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
DC OFF: Switch to this mode to prevent the inverter
from drawing power from the batteries. Use this
switch to automatically reset the unit if it shuts down
due to overload or overheating. First remove the
excessive load or allow the unit to sufficiently cool
(applicable to your situation). Switch to "DC 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. The
remote control module (Tripp Lite model APSRM4) may also be
used to reset the unit due to overload and overtemperature.
CAUTION: The unit will always pass AC power through to connected equipment if plugged into a live AC outlet, regardless of
the position of the Operating Mode Switch.

Resetting Your Inverter/Charger 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
electrical system. To restore normal functioning:
Overload Reset: Switch operating mode switch to “DC 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
Output Circuit Breaker Reset: If tripped, remove a portion of the load, wait one minute and then press breaker button to reset.
Set Configuration DIP Switches
Using a small tool, set the Configuration DIP Switches (located on the front panel, see diagram) to optimize Inverter/Charger operation

Load Sharing
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
at this high charging occurs, the AC input circuit breaker could trip, resulting in the complete shut off of pass-though utility power.
To reduce the chance of tripping this breaker, the Inverter/Charger automatically limits the input current as described below.
Note: Load sharing is factory preset and is not affected by the position of the B2 and B1 DIP switch.
Charger-limiting takes effect the moment any 120V AC load is applied; charger output falls gradually from full output
at no 120V load passing through to no output at full load.
Select Equalize Battery Charge—OPTIONAL
This DIP Switch is momentarily engaged to B4 B3 B2 B1 Reset
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.
B4 B3 B2 B1
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.
Set Battery Charging Amps—OPTIONAL
Check specifications for your unit’s highB4 B3 B2 B1
and low-charging amp options. By setting
on high charging, your batteries will charge
at maximum speed and your 12V DC
system loads will be well-supplied. When
setting 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) Dial—OPTIONAL
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 unit detects a load, it automatically turns its inverter function on. Users
may choose the minimum load the Inverter/Charger will detect by adjusting the Battery Charge Conserver Dial (see diagram).
Using a small tool, turn the dial clockwise to lower the minimum load that will be detected, causing the inverter to turn on for
smaller loads. When the dial is turned fully clockwise, the inverter will operate even when there is no load. Turn the dial 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 dial is fully clockwise. However, based on the threshold load to which you’d like the inverter to respond, you should adjust the dial 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 feature an 8-conductor telephone style receptacle on the front panel for use with the remote control module (Tripp Lite model APSRM4,
included with this model). The remote module allows the Inverter/Charger to be mounted in a compartment or cabinet out of sight, while operated conveniently from within the cab or patient care area of the vehicle. See instructions packed with the remote control module.
Ignition Interlock Control function (optional): This function automatically disables (turns OFF) AC power
output from the Inverter/Charger when the vehicle’s ignition switch is placed in the “Engine Run” position.
This function will satisfy local codes and requirements concerning video monitors or TVs that are located
within a driver’s view by automatically turning them off when the engine is started.
Battery Selection
Select Auxiliary Battery Type
(if any)
Select “Deep Cycle” batteries to receive optimum performance from your Inverter/Charger. Do not use ordinary car or starting batteries or batteries rated in
Cold Cranking Amps (CCA). If the batteries you connect to the Inverter/Charger are not true Deep Cycle batteries, their operational lifetimes may be significantly
shortened. If you are using the same battery bank to power the Inverter/Charger as well as DC loads, your battery bank will need to be appropriately
sized (larger loads will require a battery bank with a larger amp-hour capacity) or the operational lifetimes of the batteries may be significantly shortened.
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. In
many cases, the vehicle battery may be the only one installed. Auxiliary batteries must be identical to the 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/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 and the support of your vehicle’s alternator if the engine is kept running.
• STEP 1: Determine Total Wattage Required
Add the wattage ratings of all equipment you will connect to your 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 determine 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.
• 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 exclusively from battery power before
you have to recharge your batteries with utility- or generator-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.
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
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).
NOTE! For Tripp Lite Inverter/Chargers providing 1250 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. 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.
270 Amp-Hours ÷ 55 Amps
Inverter/Charger Rating = 5 Hours Recharge
WARNING! Mount your Inverter/Charger BEFORE DC battery and AC power
connection. Failure to follow these instructions may lead to personal injury and/
or damage to the Inverter/Charger and connected systems.
Tripp Lite manufactures a variety of different Inverter/Chargers with a variety of different mounting options for use in vehicular or non-vehicular
applications. Tripp Lite recommends permanent mounting of your Inverter/Charger in any of the configurations illustrated below. User must
supply mounting hardware and is responsible for determining if the hardware and mounting surface are suitable to support the weight of the
Inverter/Charger. Contact Tripp Lite if you require further assistance in mounting your Inverter/Charger.
Horizontal Mount
Using the measurements from the diagram, install two user-supplied ¼" (6 mm) fasteners into a
rigid horizontal surface, leaving the heads slightly raised.

The polycarbonate cabinet and mounting feet of your Inverter/Charger are durable enough to allow for wall mounting as well (if your
vehicle compartment requires this configuration). For wall mounting, the control panel of the Inverter/Charger must face to the side and not
up or down.
Allow 2" minimum front and rear clearance for adequate ventilation.
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 2/0 gauge)
to fit your Inverter/Charger’s DC Input terminals. Shorter and heavier
Rear-Mounted DC Connectors
gauge cabling reduces DC voltage drop and allows for maximum
transfer of current. Your Inverter/Charger is capable of delivering peak
Maximum Recommended DC Cable Length:
wattage at up to 200% of its rated continuous wattage output for
brief periods of time. Heavier gauge cabling should be used when
Max Distance from Battery to Unit in Feet
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 efficient connection and to prevent
excessive heating at this connection. Insufficient tightening of the
terminals could void your warranty.
• 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/Charger model. All installations must comply with
national and local codes and ordinances.
• Connect Fuse: NEC (National Electrical Code) article 551 requires that you connect your Inverter/Charger’s positive DC Terminals directly
to a UL-listed fuse(s) and fuse block(s) within 18 inches of the battery. The fuse’s rating must equal or exceed the Minimum DC Fuse Rating
listed in your Inverter/Charger’s nameplate. See diagrams on page 9 for proper fuse placement.
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.
Your Inverter/Charger’s Nominal DC Input Voltage must match the voltage of your battery or batteries—12 Volts in most vehicular applications.
It is possible to connect your Inverter/Charger to the main battery within your vehicle’s electrical system. In most vehicles, the Inverter/Charger will be
connected 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/Charger, 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). 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. DoubleBoost™ Feature: 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.
OverPower™ Feature: 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 model, 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. Plug your equipment into the Inverter/Charger’s AC
receptacles. Any equipment you connect to it will benefit from your Inverter/Charger’s built-in ISOBAR® surge protection!
Before returning your Inverter/Charger 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/Charger to the dealer. Instead, call Tripp Lite at (773) 869-1234. A service
technician will ask for the Inverter/Charger’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/Charger to avoid damage during shipping. Do not use Styrofoam beads for packaging.**
Any damages (direct, indirect, special, incidental or consequential) to the Inverter/Charger incurred during shipment to Tripp Lite or an
authorized Tripp Lite service center is not covered under warranty. Inverter/Chargers 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/Charger is
within the warranty period, enclose a copy of your sales receipt. Return the Inverter/Charger 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.
Your Inverter/Charger 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.
Try these remedies for common Inverter/Charger problems before calling for assistance. Call Tripp Lite Customer Service at (773) 869-1234
before returning your unit for service.
