TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, EXPLOSION OR INJURY:

• Do not connect to AC distribution wiring

• Remove appliance plug from outlet strip or turn off inverter before
working on the appliance. Multiple outlet power strips with switches
and circuit breakers only interrupt power to the "hot" receptacle
terminals. The "neutral" terminals remain powered with respect to
the "ground" terminals

• Do not make any electrical connections or disconnections in areas
designated as IGNITION PROTECTED. This includes 12 volt DC plug
connections, and ring terminal connections

• This is not a toy - keep away from children

CAUTIONS

• Do not use with positive ground electrical systems (the majority of
modern automobiles, RVs, trucks and boats are negative ground).
Reverse polarity connection will result in a blown fuse and may cause
permanent damage to the inverter and will void warranty

• This inverter will not operate high wattage appliances or equipment
that produce heat, such as hair dryers, microwave ovens and toasters

• Grounding the Neutral will cause the inverter to shut down. Do not
operate this inverter if it is wet. Do not install in engine compartment ­install in a well ventilated area

• This inverter is not tested for use with medical devices.

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. 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.

1. INTRODUCTION

Your new Vector MAXX 750 SST inverter is one in a series of the most advanced
DC to AC inverters available. With proper care and appropriate usage, it will
give you years of dependable service in your car, truck, RV or boat.

The MAXX 750 SST supplies 750 watts of continuous power, with a 1500 watt
peak, in the form of three household-type outlets that are ready to deliver 110 volt
AC power whenever and wherever you need it! The heavy-duty inverter has
enough power to run most household or electronic appliances. It also comes
equipped with battery clips to handle higher amperage/load applications, such as
power tools, stereo amplifiers, vacuums, etc. Added safety features include automatic
shutdown and a low battery alarm to prevent damage to your battery.

This power inverter is configured with the latest Soft Start Technology (SST). Before
introduction of soft-start, high start-up currents from large inductive loads could
shut down the inverter. Soft start improves inverter operation. Three major features
incorporated in SST include: first, gradual voltage ramp-up during inverter start-up.
This eliminates failed cold starts under load. Second, output that momentarily dips in
voltage and quickly recovers to allow large motorized loads to start. This eliminates
almost all shutdowns from momentary overloads. Last, the inverter automatically
re-starts when an overload that causes inverter shutdown is removed. Previously,
manual reset was required.

This power inverter also incorporates a new cooling technology that directly benefits
our customers. The new design more efficiently cools the power transistors, and
combined with soft start, dramatically increases reliability and the life of the product.

2. CONTROLS, INDICATORS AND CONNECTORS

Figure 1 details the front panel of the inverter. The front panel provides two LED
indicators. A green LED shows proper operation when lit. The red LED shows inverter
shutdown from overload, over voltage or over temperature. Power is supplied through
two grounded standard North American outlets. Outlets accommodate either two or
three pin AC plugs. An ON/OFF switch turns the inverter circuitry ON and OFF. The
switch is used to force a reset of inverter circuits if it is switched OFF, then ON.

3. HOW YOUR VECTOR INVERTER WORKS

The inverter converts low voltage DC (direct current) from a battery or other power
source to standard 110 volt AC (alternating current) household power.

3.1 PRINCIPLE OF OPERATION

The inverter converts power in two stages. The first stage is a DC-to-DC conver­sion process that raises the low voltage DC at the inverter input to 145 volts DC.
The second stage is the actual inverter stage that converts the high voltage DC into
110 volts, 60 Hz AC.

The DC-to-DC converter stage uses modern high frequency power conversion
techniques that have replaced the bulky transformers found in less technological­ly-advanced models. The inverter stage uses advanced power MOSFET transistors
in a full bridge configuration. This ensures excellent overload capability and the
ability to operate reactive loads like small induction motors.

3.2 THE MAXX 750SST OUTPUT WAVEFORM

The AC output waveform of the MAXX 750 SST 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.

HIGH SPEED COOLING FAN

(+) DC POWER CONNECTION(–) DC POWER CONNECTION

The modified sine wave produced by the MAXX 750 SST inverter has an RMS
(root mean square) voltage of 110 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 87, Fluke 8060A, Fluke 77/99 series,
Beckman 4410, or Triplett 4200.

4. INSTALLATION

4.1 POWER SOURCE REQUIREMENTS

The power source must provide between 10.5 and 15.5 volts DC and must be
able to supply the necessary current to operate the load. The power source may
be a battery or a well-regulated DC power supply. To obtain a rough estimate of
the current (in amperes) the power source must deliver, simply divide the power
consumption of the load (in watts AC) by 10.

Example: If a load is rated at 750 watts AC, the power source must be able to deliver:
750 divided by 10 = 75 amperes

CAUTION: The MAXX 750 SST must be connected only to batteries with a nominal

output voltage of 12 volts. The unit will not operate from a 6 volt battery
and will sustain permanent damage if connected to a 24 volt battery.

4.2 CONNECTION TO POWER SOURCE

The MAXX 750 SST comes equipped with battery clip cables for connection to the
power source:

CAUTION: Do not use with positive ground electrical systems (the majority of modern

automobiles, RVs, and trucks are negative ground).

To operate at full 750 watts output, either use the battery clip cable (supplied) or
directly wire to the power source with user supplied wire and fuse. Use wire #8
AWG for lengths of four feet or less and #6 AWG for lengths to 10 feet.

CAUTION: Reverse polarity connection will result in a blown fuse and may cause

permanent damage to the inverter.

CONNECTING TO A POWER SOURCE USING PROVIDED CABLES:

Use the provided cables to connect the MAXX 750 SST directly to the 12 volt
power source using the following guidelines:

1. Check to be sure the MAXX 750 SST power switch is turned off and that

no flammable fumes are present.

2. Connect the black cable to the black post marked “(-)” on the back of the

inverter. Connect the battery clip to the negative terminal of the battery.

3. Connect the red cable to the red post marked “(+)” on the back of the

inverter. Connect the battery clip to the positive terminal of the battery.

4. Check to be sure that all connections between battery clips and terminals
are secure.

DIRECT HARDWIRING TO POWER SOURCE:

Use #8 AWG wire if the inverter to power source connection is 4 feet or less. For
longer cable lengths use #6 AWG wire for lengths up to 10 feet. In either case,
protect the positive (+) wire from shorts by installing a 150 Amp fuse or circuit
breaker close to the DC power source (battery) terminal.

1. Check to be sure the inverter’s power switch is turned off and that no

flammable fumes are present.

2. Identify the positive (+) and negative (-) DC power source (battery) terminals.

3. Install a fuse holder or breaker close to the positive (+) terminal of the

DC source (battery).

4. Connect a length of wire on one side of the fuse holder or circuit breaker.

Connect the other end of the wire to the Positive (+) terminal of the inverter.

5. Connect a length of wire between the inverter’s negative (-) terminal and
the DC power source negative (-) terminal.

6. Connect a short length of wire to the other terminal of the fuse holder or
circuit breaker. Mark it “POSITIVE” or “+”.

7. Connect the free end of the fuse or breaker wire to the positive terminal
of the DC power source (battery).

8. Insert an 150 amp fuse in the fuse holder.

9. Test the inverter by turning it on and plugging in a 100 watt lamp or

equipment.

10. If the inverter is not properly operating, then refer to the trouble-shooting
sections of this manual.

CAUTION: Loose connectors may cause overheated wires and melted insulation.

Check to make sure you have not reversed the polarity. Damage due to
reversed polarity is not covered by our warranty.

4.3 CONNECTION TO LOAD

The MAXX 750 SST is equipped with dual standard North American AC power
receptacles. Plug the cord from the equipment you wish to operate into the
AC receptacle(s). The green LED indicator lights to indicate that the inverter is
functioning. Make sure the combined load requirement of your equipment does
not exceed 750 watts.

The MAXX 750 SST 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!
CAUTION: RECHARGEABLE APPLIANCES-Certain rechargeable devices are designed

to be recharged only by plugging them directly into an AC receptacle.
These devices may damage the inverter. Do not use the inverter to
recharge items that can only be plugged directly into an AC receptacle.

This problem does not occur with the majority of battery-operated equipment.
Most of these devices use a separate charger or transformer that is plugged into
an AC receptacle. The MAXX 750 SST is easily capable of running most charg­ers and transformers.

4.4 PLACEMENT OF THE INVERTER

For best operating results, the inverter should be placed on a flat and/or solid
surface. A power cord measuring 3 feet (1.0 meter) has been provided for easy
positioning of the inverter. The inverter should only be used in locations that meet
the following criteria:

DRY - Do not allow water and/or other liquids to come into contact with the
MAXX 750 SST inverter.

COOL - Ambient air temperature should be between 30°F (-1°C) non-condensing,
and 105°F (40°C). Do not place the inverter on or near a heating vent or any
piece of equipment which is generating heat above room temperature. Keep the
inverter away from direct sunlight, if at all possible.

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. A fan is helpful if the inverter is operating at maximum power outputs
for extended periods of time. The unit will shut down if the internal temperature
exceeds operating temperatures. The unit will restart after it cools.

SAFE - Do not use the inverter near flammable materials or in any
locations that may accumulate flammable fumes or gases.

5. OPERA

TING TIPS

5.1 RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT

Most electrical tools, appliances and audio/video equipment have labels that
indicate the power consumption in amps or watts. Be sure that the power
consumption of the item you wish to operate is rated at 750 watts or less

(If the power consumption is rated in amps AC, simply multiply by the AC volts
(110) to determine the wattage). The inverter has overload protection, so it is safe
to try to operate equipment rated at 750 watts or less. The inverter will shut down
if it is overloaded. The overload must be removed before the inverter will restart.
Resistive loads are the easiest for the MAXX 750 SST to run. However, larger
resistive loads, such as electric stoves or heaters, usually require more wattage
than the MAXX 750 SST can deliver on a continuous basis. Inductive loads, such
as TV’s and stereos, require more current to operate than do resistive loads of the
same wattage rating. Induction motors, as well as some televisions, may require
2 to 6 times their wattage rating to start-up. The most demanding in this category
are those that start under load, such as compressors and pumps. Testing is the only
definitive way to determine whether a specific load can be started and how long
it can run. The unit will simply shut down if it is overloaded. To restart the unit after
a shutdown due to overloading, remove the overload.

CAUTION: This inverter will not operate high wattage appliances or equipment that

produce heat, such as hair dryers, microwave ovens, and toasters.

5.2 BATTERY OPERATING TIME

With a typical vehicle battery, a minimum operating time of 1 to 2 hours can be
expected. In most instances, 5 to 10 hours of operating time is achievable. However,
Vector recommends that the operator start the vehicle every hour to recharge the
battery system. This will guard against any unexpected shut-down of the equipment
and will ensure that there is always sufficient battery capacity to start the vehicle’s
engine. The inverter will sound it’s alarm when DC voltage drops to 10.6 volt.

The inverter may be used whether or not the vehicle’s engine is running. However,
the inverter may not operate while the engine is starting since the battery voltage
can drop substantially during cranking. The inverter draws less than 0.4 ampere
from the battery when it is not supplying power to a load and switch is in the ON
position. In most instances, the inverter can be left connected to the battery when
not in use since it draws so little current. However, if the vehicle is to remain
unused for several days, disconnect the inverter from the battery.

6. PROTECTIVE FEA

TURES OF THE INVERTER

Your MAXX 750 SST monitors the following potentially hazardous conditions:
LOW BATTERY VOLTAGE - This condition is not harmful to the inverter but could

damage the power source. An audible alarm will sound when input voltage drops
to 10.6. The MAXX 750 SST automatically shuts down when input voltage drops
to 10.0 volts. When the condition is corrected, the unit may be restarted.

9

OVER VOLTAGE PROTECTION - The MAXX 750 SST will automatically shut down
when the input voltage exceeds 15.5 volts DC.

SHORT CIRCUIT PROTECTION - Reverse polarity or a short circuit condition will
usually result in an external or internal fuse being blown.

OVERLOAD PROTECTION - The inverter will automatically shut down when the
continuous draw exceeds 750 watts. When the overload is removed the inverter
will self-start.

OVER TEMPERATURE PROTECTION - If the temperature inside the MAXX 750 SST
is too high to operate, the unit will automatically shut down. Allow the unit to cool
for at least 15 minutes before restarting after a heat-related shutdown. Unplug
unit while cooling.

LOW BATTERY ALARM - An alarm will sound when the voltage from the battery
drops to 10.6 volts. This is an indication that the battery needs to be recharged.
The user should stop operation of the electronic device at this time, since the
inverter will shut down automatically shortly thereafter, when the battery voltage
drops to 10 volts. Start your engine to recharge the battery.

If the low voltage alarm sounds when the battery is fully charged, follow the steps
for solving lack of output power in the Troubleshooting Guide. The alarm will
sound when the inverter is overloaded, in thermal shutdown, or if there is an
excessive voltage drop between the battery and inverter.

NOTE: It is normal for the alarm to sound while the unit is being connected to,

or disconnected from, the power source. This is not indicative of a problem.

7. COMMON PROBLEMS

“BUZZING” SOUND IN AUDIO SYSTEMS:
Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from

their speakers when operated from the MAXX 750 SST 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 Vector MAXX 750 SST 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 that the antenna feeding the television provides an adequate
(“snow free”) signal and that high quality, shielded antenna cable is used

9. FUSE REPLACEMENT

If external fuses blow, (or breakers trip), then there is a short or overload in the DC
wiring. Find and fix the problem before replacing the fuses (or resetting the breaker).
After fuse replacement, reconnect the inverter.

This power inverter is equipped with multiple internal fuses. Normally, these fuses
will not blow unless there is a serious problem inside the unit. Internal fuses are
replaceable, however, only electronically knowledgeable people should attempt fuse
replacement. If the unit is damaged during fuse replacement, the warranty may be
voided. Vector recommends contacting Technical Support for guidance. Based on
experience, it is best to return the unit to Vector for repair. Vector Technical Support
