INTRODUCTION  
Your new Vector MAXX 400 SST inverter is one in a series of the  
mostadvanced DC to AC inverters available today. With proper  
careandappropriate usage, it will give you years of dependable service in  
your car, truck, RV or boat.  
The MAXX 400 SST supplies 400 watts of continuous power, with a 800  
watt peak, in the form of two 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, including color TVs (up to 25"), TV/VCR combinations, laptop  
computers, camcorders, cellular phone, power tool chargers, lamps and  
many more. It also comes equipped with battery clips to handle higher  
amperage/load applications, such as; power tools, stereo amplifiers (up to  
275 watt RMS), 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)  
to improve inverter operation. Before introduction of soft-start, high start-  
up currents from large inductive loads could shut down the inverter. Three  
major features are incorporated in SST. First, gradual voltage ramp-  
upduring inverter start-up. This eliminates failed cold starts underload.  
Second, output that momentarily dips in voltage and quickly recovers. This  
eliminates most shutdowns from momentary overloads. Last, the inverter  
needs to be turned off then turned on to re-start the inverter when an  
overload that caused inverter shutdown is removed.  
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.

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  
reset of inverter circuits if it is switched OFF, then ON.

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.

3.2 THE MAXX SST 400 WATT OUTPUT WAVEFORM  
The AC output waveform of the MAXX 400 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.  
The modified sine wave produced by the MAXX 400 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)  
a
r
e
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.

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.  
6
 
6
Example: If a load is rated at 400 watts AC, the power source must be able  
to deliver: 400 divided by 10 = 40 amperes  
CAUTION: The MAXX 400 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 400 SST comes equipped with a 12 volt DC plug and 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)  
Connecting to Power Source Using 12 volt DC Plug:  
The 12 volt DC plug is suitable for operating the inverter at power outputs  
up to 175 watts. The tip of the plug is positive and the side contact is  
negative. Connect the MAXX 400 SST to the power source by inserting the  
12 volt DC plug firmly into the 12 volt DC socket of a vehicle or other DC  
power source.  
CAUTION: Connect directly to power source when operating above  
175 watts.  
NOTE: Most automobile 12 volt DC circuits use fuses rated at 15 to 20  
amps or greater. To operate at full 400 watts output, either use the  
battery clip cable (supplied) or directly wire to the power source with  
user-supplied wire and fuse. Caution: Reverse polarity connection will  
result in a blown fuse and may cause permanent damage to the inverter  
and will void the warranty.  
Connecting to a Power Source Using Provided Cables:  
If the inverter is to be used for extended periods at power levels above 175  
watts, direct connection to the power source is required. Use the provided  
cables to connect the MAXX 400 SST directly to the 12 volt power source  
using the following guidelines:  
1. Check to be sure the MAXX 400 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.  
 
7
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 #10 AWG wire if the inverter to power source connection is 12 feet or  
less. For longer cable lengths use #8 AWG wire. In either case, protect the  
positive (+) wire from shorts by installing a 50 Amp fuse or circuit breaker  
close to the DC power source (battery) terminal.  
1. Check to be sure the inverters 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 if the wire to the positive (+) terminal of the inverter.  
5. Connect a length of wire between the inverters 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 a 50 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 400 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 400 SST watts.  
The MAXX 400 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 by  
plugging them directly into an AC receptacle. These devices may  
damage the inverter. Do not use the inverter to recharge items that q  
can 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 400 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 surface,  
such as the ground, car floor or other 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 400 SST inverter.  
COOL - Ambient air temperature should be between 30 degrees F (-1  
degree C) non-condensing, and 105 degrees F (40 degrees 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  
 
9
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.  
OPERATING 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 400 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 400 watts or  
less. The inverter will shut down if it is overloaded. The overload must be  
removed before the inverter can be manually restarted by reseting the  
on/off switch. Resistive loads are the easiest for the MAXX 400 SST to run.  
However, larger resistive loads, such as electric stoves or heaters, usually  
require more wattage than the MAXX 400 SST can deliver. Inductive loads,  
such as TVs and stereos, require morecurrent 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 and reset the on/off switch.  
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 2 to 3 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  
10  
 
10  
every 2 to 3 hours 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 vehicles engine. The inverter  
will sound its alarm when DC voltage drops to 10.6 volt.  
The inverter may be used whether or not the vehicles 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. In most instances, the inverter can be left  
connected to the battery when not in use since it draws so little current  
when the power switch is in the ON position. However, if the vehicle is to  
remain unused for several days, disconnect the inverter from the battery.  
6.  
PROTECTIVE FEATURES OF THE INVERTER  
Your MAXX 400 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 400 SST automatically shuts down when  
input voltage drops to 10.0 volts. When the condition is corrected, the  
unit may be restarted.  
OVER VOLTAGE PROTECTION - The MAXX 400 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 fuse being blown.  
OVERLOAD PROTECTION - The inverter will automatically shut down  
when the continuous draw exceeds 400 watts.  
OVER TEMPERATURE PROTECTION - If the temperature inside the MAXX  
400 SST is too hot 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  
 
11  
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 400 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 400 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.

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  
Vector Technical Support for guidance. Based on experience, it is best to  
return the unit to Vector for repair. Vector Technical Support can be
