IMPORTANT CABLE INFORMATION:
Substantial power loss and reduced battery operating time results from inverters installed with cables that are
not able to supply full power. Symptoms of low battery power can result from cables that are either excessively
long or an insufficient gauge. Marine installations are also subjected to vibration and stresses that exceed those
of other mobile installations. Therefore, the installer/operator should be especially aware of the requirements to
maintain secure, tight, water-resistant electrical connections and to provide for strain relief for DC cables and
appliance wiring. Cable insulation must be the appropriate type for the environment.
• Read And Understand This Instruction Manual Before Using This Unit.

INTRODUCTION
Thank you for purchasing the VEC054D MAXX SSTTM Compact Power Inverter. Please read this Instruction
Manual carefully before use to ensure optimum performance and to avoid damage to this product.
This Power Inverter is configured with the latest Soft Start Technology (SST) and supplies continuous power
and peak watts in the form of 120 volt AC outlets to run most household or electronic appliances. Before
introduction of SST, high start-up currents from large inductive loads could shut down an inverter. SST
improves inverter operation by:
• Gradual voltage ramp-up during inverter start-up, eliminating failed cold starts under load.
• Output that momentarily dips in voltage and quickly recovers to allow large motorized loads to start, eliminating
most shutdowns from momentary overloads.
• A new technology that cools the power transistors more efficiently, and, combined with Soft Start, dramatically
increases reliability and life of the product.
Added safety features include automatic shutdown and a low battery alarm to prevent damage to your battery.
FEATURES
On the front panel are two LED indicators. The green LED indicates power and proper operation of the inverter;
the red LED indicates inverter shutdown from over-load or over-temperature condition, or abnormal input
voltages. The ON/OFF Switch turns the inverter ON and OFF. The switch can also be used to force reset of
inverter circuits by switching it OFF, then back ON again. All models also feature a port to attach a remote
control (sold separately).
120 volt AC power is supplied through three North American three-prong type outlets. The outlets can
accommodate either two- or three-pin AC plugs.

• AC short-circuit shutdown
• Low voltage audible alarm (sounds at 10.5 volts input)
• Low-voltage shutdown (activates at 10.0 volts DC)
• High-input voltage shutdown (activates at above 15.5 volts DC)
MAXX SST™ uses a 12 volt DC power source like those found in motor vehicles, or it can be operated using
multiple battery configurations with commercial battery chargers or solar battery chargers. For most heavy-duty
applications, a multiple battery configuration and the use of deep-cycle batteries is required.
When using multiple batteries, inverters can be operated from one of the vehicle 12 volt batteries, so there’s
always one battery with adequate charge to start an engine.
MAXX SST™ includes a high-surge capability. This is required to start heavy loads, such as motors and other
inductive devices.
PRINCIPLE OF OPERATION
The MAXX SST™ inverter converts 12 volt DC (direct current) from a vehicle battery or other 12 volt DC power
source to standard 120 volt AC (alternating current) household power.
It converts power in two stages (see the diagram below). In the first stage, the inverter raises the 12 volt DC
input to 145 volts DC. This MAXX SST™ inverter uses high-frequency conversion techniques that replace bulky
and heavy transformers found in older inverters. In the second (output) stage, the inverter converts the 145 volt
DC to 110/120 volt AC using multiple banks of metal-oxide semiconductor field-effect transistors (MOSFETs).
The unit’s solid-state circuitry ensures excellent overload protection and the ability to operate reactive loads
such as those found in inductive motors. In this stage, the inverter functions as a high-power bipolar switch,
alternately applying opposite polarity to the AC outlet HOT and NEUTRAL terminals.

The Power Inverter Output Waveform
The AC output waveform of the Power Inverter is known as “modified sine wave.” It is a waveform that has
characteristics similar to the sine wave shape of utility power. This type of waveform is suitable for most AC
loads, including linear and switching power supplies used in electronic equipment, transformers, and motors.
The modified sine wave produced by the Power Inverter has an RMS (root mean square) voltage of 115 volts,
which is the same as standard household power. Most AC voltmeters (both digital and analog) are sensitive to
the average value of the waveform rather than the RMS value. They are calibrated for RMS voltage under the
assumption that the waveform measured will be a pure sine wave. These meters will not read the RMS voltage
of a modified sine wave correctly. They will read about 20 to 30 volts low when measuring the output of the
inverter. For accurate measurement of the output voltage of this unit, use a true RMS reading voltmeter such as
a Fluke 179, Fluke 79 III series, Beckman 4410 or Triplett 4200.

APPLIANCE POWER CONSUMPTION
MAXX SST™ inverters are ideal for powering:
• Lights
• TVs and TV/DVD (VCR) combinations units
• Radio receivers/transceivers and stereo systems
• Computers and peripheral equipment
• Refrigerator/freezers
• Small microwave ovens
• Household appliances
• Dry and/or wet/dry vacuums
• Heavy duty power tools & chargers
• Sump pumps, motors and other electric-powered equipment
Most electrical tools, appliances and audio/video equipment have labels that show the unit’s power
consumption in amps, watts, or both. To avoid inverter shutdown and possible damage to the inverter, avoid
exceeding the wattage rating of this unit. To obtain a rough estimate of the current (in amperes) the power
source must deliver where the power consumption of the tool or device is given in watts AC, simply divide the
power consumption of the load by 10.
Example: If a load is rated at 200 watts AC, the power source must be able to deliver: 200 divided by 10 = 20
amperes.
The inverter has built-in overload protection so that if you do exceed the inverter’s output capacity continuously,
the unit will automatically shut down. Once the excessive load is removed, the inverter can be restarted and
resume normal operation.
Note: To restart the inverter, turn it off, and then on again. The on/off Switch is located on the unit’s Front Panel
(refer to the “Control and Functions” section of this Instruction Manual).
The inverter powers resistive loads the easiest; however, larger resistive loads, such as electric stoves or
heaters, could draw more wattage than the inverter can deliver on a continuous basis.
CAUTIONS
Ensure that total continuous power consumption of all tools and/or appliances connected to the inverter (and in
use) does not exceed the inverter’s continuous watts rating. Also ensure that start-up wattage for inductive
loads does not exceed peak watts for more than a second.
Appliances such as microwave ovens will normally draw more than their rated current and could possibly
overload the inverter when operating simultaneously with other appliances. For example: A 600 watt
microwave oven draws approximately 940 watts.
The following chart shows the approximate amperage and corresponding wattage at 120 volts AC for various
common tools and appliances.

Note: Appliance specifications may vary from brand to brand. This table is offered only as a guide to approximate
power ratings. Check appliance manuals or product labeling for actual ratings. For continuous use at
maximum output, the MAXX SST™ inverter must be connected to a DC power supply capable of providing
at least 1/10th of the inverter’s continuous wattage rating.
The inverter will operate most AC loads within its power rating. Some induction motors used in refrigerators,
freezers, pumps and other motor-operated equipment, require very high surge currents to start them. The
inverter may not be able to start some of these motors even though their rated current draw is within
specifications for this power inverter.
If a motor refuses to start, observe the battery voltage using a DC voltmeter while trying to start the motor. If
the battery voltmeter drops below 11 volts while the inverter is attempting to start the motor, this may be why
the motor won’t start. Make sure the battery connections are tight and the battery (or batteries) is (are) fully-
charged. If the connections are good and the battery is charged, but the voltage still drops below 11 volts, you
may need to use a larger battery (or battery combination).
CAUTION
Rechargeable Devices
Certain rechargeable devices do not operate well from a modified sine wave inverter. They only operate properly
from a standard household outlet, which provides a pure sine wave. Therefore, the manufacturer recommends
that these types of devices be operated from a standard household outlet only, not from the inverter.
This problem does not occur with most battery-operated equipment. Most of these devices use a separate
charger or transformer that is plugged into an AC receptacle. This inverter is easily capable of running most
chargers and transformers.
OPERATING INSTRUCTIONS
Power Source Requirements
The inverter will operate from input voltages between 11 and 15 volts DC. If the voltage drops below 10.5 volts,
an audible low battery warning alarm will sound. The inverter will shut down if the input voltage drops below 10
volts DC. This built-in feature protects the battery from being completely discharged.
The inverter will also shut down if the input voltage exceeds 15.5 volts. This
protects the inverter against excessive input voltage. Although the inverter has built-in protection against over
voltage, it may still be damaged if the input voltage exceeds 15.5 volts.
Inductive loads, such as TVs and stereos, require more current to operate than do resistive loads with the same
wattage rating. Induction motors, as well as some TVs, may require two to six times their rated wattage to start
up. Because the MAXX SST™ inverters have a peak watt power rating, many such appliances and tools may be

safely operated. The equipment that needs the highest starting wattage are pumps and compressors that start
under load. This equipment can be safely tested. If an overload is detected, the inverters will simply shut down
until the overload situation is corrected. Use the front panel switch to turn OFF the inverter, then ON, to reset
the inverter.
CAUTIONS
Exceeding recommended voltage limits will void manufacturer’s warranty.
NEVER try to use the inverter with any 12 volt DC power source that uses a positive ground. (Most vehicles and
boats use negative ground systems.)
The DC power source must be a well-regulated DC power supply as typically found in vehicle and deep-cycle
marine batteries. The DC power source may also be two 12 volt batteries connected in parallel. On larger
applications the power source may be several batteries connected in parallel as shown in the following “Battery
Wiring” diagram.

Note: For typical heavy-duty uses, the manufacturer recommends a specified or equivalent ANL fuse be added as
close as possible to the power source (battery) positive terminal. The fuse amperage size must be
appropriate to allow simultaneous operation of all the AC appliances to be powered, with delay
characteristics that allow for the momentary high start-up current requirements of inductive loads. Use the
recommended fuse block (fuse holder) and fuse, or an electrical equivalent. For full rated output and motor
start-up surge output, ensure that the installation is configured to handle the full load. See the
“Specifications” section of this Instruction Manual.
Determining Battery Size
To determine the minimum battery size you will need to operate appliances from MAXX SST™ inverters, follow
these steps:
1. Determine the wattage of each appliance and/or tool you will need to simultaneously operate from the
inverter. To do this, read the labels on the equipment to be operated.
2. Estimate the number of hours the equipment will be in use between battery recharges.
3. Determine the total watt-hours of energy use, the total running time and the average power consumption.
Keep in mind that some appliances are not drawing the same power continuously. For example, a typical home-
use coffee maker draws 500 watts during brew time (approx. 5 minutes), but maintains the pot temperature at
only about 100 watts. Typical use of a microwave is only for a few minutes, sometimes at low power.
Runtime
The following graph is a set of curves that show how appliance load, in watts or in amperes, affects runtime.
These curves are only estimates of operating time, dependent upon:
• The condition of the batteries
• The state of charge on the batteries
• The amount of other DC appliances drawing current from the batteries
Three curves were developed for a battery of 50 Ampere Hours (AH) capacity, and three for multiple batteries in
parallel. The higher capacity curves are for 120 AH, 200 aH and 400 aH capacities. These large capacity
batteries clearly extend operating time at full load. To extend operating time in general, reduce the heavy
appliance load to a minimum. Remember, you are operating on stored energy and probably under power loss
conditions.

Note: All operating time curves assume permanent installation with the appropriate DC input wire (See the
“Specifications” section of this Instruction Manual) and a full charge on the batteries.

For example, as shown in the above graph, using a 400 A/h battery (batteries), if the average power usage will
be 1000 watts, the operating time will be about 150 minutes. A larger capacity battery will deliver more
operating time between recharges.
Note: The manufacturer recommends conservative estimates when selecting a battery. More amp hours will
deliver a reserve capacity, and a larger capacity battery will not be subject to deep discharges. Ideally, the
number of amp hours (A/h) you expect to use should be less than 50% of the battery’s rated capacity.
Protective Features
LOW BATTERY ALARM
An audible alarm will sound when the 12 volt DC power supply voltage drops down to 10.5 0.3 volts. This
indicates that the battery needs to be charged or there is an excessive voltage drop between the battery power
source and the inverter.
Notes: It is normal for the alarm to sound when the inverter is being connected to, or disconnected from, a 12
volt DC power source. This does not indicate a problem. However, if this alarm sounds continuously,
discontinue inverter operation and charge the battery before resuming operation. If the voltage drops to
10.0 volts DC, the inverter will automatically shut down. If the low voltage alarm sounds when the battery
is fully charged refer to the “Troubleshooting” section of this Instruction Manual).
CIRCUIT PROTECTION
The inverter has electronic circuit protection against overload or short circuit conditions.
CAUTION
If turning the ON/OFF Switch OFF then ON again does not reset the inverter, DO NOT ATTEMPT TO OPEN THE
INVERTER. Opening the inverter for any reason will void the warranty. The unit must be returned to Vector
Manufacturing for testing and repair by professional factory technicians.
INSTALLATION
MAXX SST™ inverters will provide you with continuous electrical power when powered by a 12 volt DC source,
such as a vehicle battery or a multiple battery configuration (see the diagram under “Battery Configuration,”
page 6). This manual does not describe all of the possible configurations.
Operating Environment
Do not locate inverters in an area, room or compartment where explosives or flammable fumes might be
present, such as engine rooms, engine compartments, and boats or small, unvented battery compartments.
To avoid possible dangerous conditions, the inverters must be located where:
1. The unit is kept dry;
2. Air temperature is between 30°F (–1°C), non-condensing, and 105° F (40°C);
8
Download from Www.Somanuals.com. All Manuals Search And Download.
3. At least three inches of clearance from other objects is maintained for cooling airflow;
4. The unit is not exposed to direct heat, sunlight or to explosive or flammable fumes; and
5. The unit is as close to the DC power source as possible.
Never connect the chassis ground wire from the inverter to the DC negative input.
• CHECK to ensure that the combined loads of the appliances being powered by the inverter DO NOT continuously
exceed the inverter’s wattage rating.
• NEVER place items on or over the inverter during operation.
MAXX SST™ inverters generate heat during operation and must be placed where cool air can circulate to the
internal fan, and hot air can be removed.
For optimum operation, the inverter should be placed or mounted on a flat
surface; ideally, a normally cool metal surface to help diffuse the heat that is generated. Two cables (see the
diagram on page 8) are not supplied, but will be required to allow for full power operation and to provide
flexibility in positioning the inverter.
Marine Applications
In all marine applications, DO NOT install the inverter below or near the waterline, and keep the inverter away
from moisture and water.
Use ONLY non-corrosive marine fasteners and fittings for installation. Only connect the inverter’s DC input to
existing wiring (which must be approved for marine use) at the appropriate gauge, cable and length (see the
“Specifications” section). For cable lengths exceeding 6 feet from inverter to batteries, call Vector for additional
installation information. The cable, fuse holder and fuse (not supplied) can be purchased at an electrical supply
company. The fuse holder and fuse are a specified amperage rating (see Specifications, page 16). Call Vector
Technical Support toll-free at 1-800-544-6986 with any questions.
Installation Procedures
When wiring the inverter to a 12 volt DC power source, ensure that polarity is correct. Reversed polarity will
blow a fuse and may cause permanent damage to the inverter. Review diagrams on page 3, if necessary, to
identify the location of the DC terminals.
Note: The manufacturer’s warranty does NOT cover damage due to reversed polarity.
Quick Operational Test or Emergency Use
You will need:
• A heavy-duty jumper cable set of the specified AWG wire rating (see the “Specifications” section of this
Instruction Manual)
• A fully-charged automobile battery
• A common slip joint plier for loosening and tightening terminal nuts
PROCEDURE
1. Unscrew nuts in input terminal block.
2. Identify the positive and negative terminals on the 12 volt DC battery (or other 12 volt DC power source) and
identify the positive and negative terminals on the inverter.
3. Using a set of heavy-duty jumper cables, attach the red cable to the inverter’s positive (+) terminal and the
black cable to the inverter’s negative (–) terminal.
4. Connect the clamps on the other ends of the jumper cables to the corresponding positive (+) and negative
(–) terminals on the 12 volt DC vehicle battery (or other 12 volt DC power source). There may be some
minor sparking.
5. Turn the inverter ON/OFF Switch ON.
6. Plug in a lamp with a 100 watt light bulb and switch the lamp on. If the lamp works normally, the inverter is
functioning properly and you can proceed to a permanent installation or continue to use the inverter with low
wattage appliances. If the lamp does not light or does not work correctly:
A. Check all connections and tighten any that may be loose.
B. Ensure that the source battery has adequate charge.
C. If steps A and B do not correct the problem, refer to the “Service Information” section of this Instruction
Manual for assistance.

Permanent Installation
For permanent installation to heavy-duty battery power you will need:
• Two cables (as indicated in the “Specifications” section)
• Terminals to fit cable ends and stud terminals to inverter
• Hardware and battery connector to connect cables to the battery bank
• A single length of AWG cable multi-stranded, flexible, insulated cable (as indicated in the “Specifications” section
of this Instruction Manual) for chasis ground connection
• A holder and fuse (see the “Specifications” section of this Instruction Manual)
• Mounting screws, bolts and nuts for mounting the inverter and fuse holder
• A drill for mounting the inverter and fuse holder
• Lead-tin solder, flux, propane torch and an igniter for the torch
• Wire stripper/cutting tool
PRELIMINARY STEPS
The inverter has four slots in its mounting bracket that allow the unit to be fastened against a bulkhead, floor,
wall or other flat surface. Ideally, the mounting surface should be cool to the touch. It is more efficient to use
longer AC wiring than DC wiring, so install the inverter as close as possible to the 12 volt DC power source.
Vector inverters should be operated in horizontal position; if it is to be mounted on a wall, mount it horizontally
so that indicators, switches, outlets and terminal blocks on the front panel are visible and accessible.
1. If inverter is to be installed in a vehicle, it is recommended that the unit be shock mounted to either the floor
(in a clear, safe area) or on a secure flat surface.
2. Locate a convenient place to mount the inverter and fuse holder.
3. Perform a test routing of the proposed cable length, but don’t do any cutting at this time (refer to the
diagram in the “Battery Configuration” section of this Instruction Manual).
4. Be sure that the positive (+) and negative (–) cables to the battery do not exceed six feet.
5. Using an appropriate AWG cable (see the diagram on page 7), reposition the inverter and fuse holder if
necessary.
6. After you have performed the above preliminary installation steps, proceed with the actual inverter
installation.
Contact the manufacturer for any further installation information or questions.
Note: This procedure is for using locally purchased supplies. If a Vector Cable Set is used, follow the directions
included with that set.
PERMANENT INSTALLATION PROCEDURE
The cables between the power source and inverter should be set up as illustrated in the diagram in the “Battery
Configuration” section of this Instruction Manual. Unscrew terminal nuts before beginning permanent
installation. Proceed with DC cable and fuse installation as follows:
1. Ensure the inverter’s ON/OFF Power Switch is in the OFF position.
2. Using tools and hardware, mount the inverter to a flat surface.
3. Ensure that mounting hardware does not touch any fuse holder or fuse contacts. Ensure that fuse is removed
from its holder.
4. Measure the cable twice before cutting the cable.
5. Cut one cable length to connect the negative (–) battery terminal to the inverter’s negative terminal, leaving a
little slack in the cable.
6. Cut another cable to connect the positive (+) battery terminal to one side of fuse holder, leaving a little slack.
7. Cut the final cable to connect the other side of fuse holder to the inverter’s positive (+) terminal.
8. Strip the end insulation of all three cables to 1-inch (2.45 cm).
9. Sweat-solder end ends of all cables. For safety, do this in an open space because it may require the use of a
propane torch.
10. Connect one end of the negative (–) cable to a ring terminals* going to the battery(ies).
11. Connect the short end of the positive (+) cable to a ring terminals* going to the battery(ies).
12. Crimp or clamp ring terminals of the negative (–) and positive (+) cables (going to the battery), but do not
connect the battery yet.

tighten the retaining nut.
15. Connect the other (long) end of the (+) positive cable to one terminal of the heavy-duty fuse holder.
16. Connect the other conductor of the heavy-duty fuse holder to the (short) positive (+) battery terminal.
17. Connect the other end of the (–) negative cablewith the ring terminal to the negative (–) battery terminal.
18. Connect an insulated wire (at least #12 AWG) between the chassis grounding screw on the inverter’s case
and a solid electrical ground to minimize possible electrical noise in TVs and radios. Do not connect this
wire to the negative DC input terminal.
19. Ensure that all electrical connections have been tightened.
20. Ensure that the inverter’s on/ofF Switch is in the off position.
21. Insert the fuse into the fuse holder. There may be some sparking.
22. Ensure the 12 volt DC power source has an adequate charge.
23. Turn the inverter ON and apply a test load to the 120 volt AC outlets.
* Ring terminals are not included and must be supplied by user.
If, after following all of the above steps, the inverter does not perform properly, the source voltage may be too
low or the cables may be too long (or the gauge too light). Having checked and, if necessary, corrected these
conditions, refer to the “Service Information” section of this Instruction Manual for assistance if problems
persist.
Connection To Load
The Power Inverter is equipped with standard North American three-prong type outlets. Plug the cord from the
equipment you wish to operate into the AC outlet(s). Make sure the combined load requirement of your
equipment does not exceed maximum continuous power.
The Power Inverter is engineered to be connected directly to standard electrical and electronic equipment in the
manner described above. Do not connect the Power Inverter to household or RV AC distribution wiring. Do not
connect the Power Inverter to any AC load circuit in which the neutral conductor is connected to ground (earth)
or to the negative of the DC (battery) source.
WARNING
Do not connect to AC distribution wiring!
Operating Tips
For best operating results, the inverter should be placed on a stable, flat surface. The inverter should only be
used in locations that meet the following criteria:
DRY — Do not allow water or other liquids to come into contact with the inverter.
COOL — Surrounding air temperature should be between –0°C and 40°C — ideally between 15°C and 25°C
(60-80°F). Keep the inverter away from direct sunlight, when possible.
WELL-VENTILATED — Keep the area surrounding the inverter clear to ensure free air circulation around the
unit. Do not place items on or over the inverter during operation. The unit will shut down if the internal
temperature gets too hot.
SAFE — Do not use the inverter near flammable materials or in any locations that may accumulate flammable
fumes or gases. This is an electrical appliance that can briefly spark when electrical connections are made or
broken.
Notes on Using the Remote Control (sold separately)
For ease of use, Vector offers (as a separate item) a Remote Control specifically designed for this line of MAXX
SST inverters. The inverter ON/OFF Switch must be in the OFF position when connecting the Remote Control to
the unit or the Remote Control will not operate. Once the unit has been turned ON using the Remote Control,
inverter operation will continue to be controlled through the Remote Control. Turn the inverter OFF before
disconnecting the Remote Control.
For more information about attaching and using the Remote Control, please refer to the Remote Control User’s
Manual.

TROUBLESHOOTING
Common Audio/Visual Problems
Problem
Solution
“Buzzing” sound in audio Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from
systems
their speakers when operated from the Power Inverter. This occurs because the
power supply in the electronic device does not adequately filter the modified sine
wave produced by the inverter. The only solution to this problem is to use a higher
quality sound system that incorporates a higher quality power amplified supply.
Television Interference
The Inverter is shielded to minimize interference with TV signals. However, in
some instances, some interference may still be visible, particularly with weak TV
signals. Try the following corrective measures:
• Position the inverter as far as possible from the television, the antenna and the
antenna cables. Use an extension cable, if necessary.
• Adjust the orientation of the inverter, the antenna cables and the TV power cord
to minimize interference.
• Make sure the antenna feeding the television provides an adequate (“snow
free”) signal and that high quality, shielded antenna cable is used.
• Do not use the inverter to operate high-power appliances or tools at the same
time you are using it to operate the TV.
• Make sure the inverter’s case is properly grounded (refer to the “Permanent
Installation Procedure” section of this Instruction Manual).
Resetting the Unit
After over-voltage or thermal automatic shutdown, the VEC054D will reset automatically. To reset all other units,
turn the ON/OFF Power Switch to the “OFF” position, then back “ON.”
